General Description
The SM89T16R1 is a high speed (4 clocks / machine cycle) single-chip 8-bits microcontroller manufactured in an advanced CMOS process with on chip flash memory. It supports a derivative of the 80C51 microcontroller family. The SM89T16R1 has the same instructions set as the 80C51. The SM89T16R1 contains a 64KB on chip program flash, a volatile 1280 x 8 bits data RAM, four 8-bits I/O ports, one 4-bits I/O port, two 16-bits timer/event counters, and an additional 16-bits timer coupled to capture and compare latches, a two-priority-level, nested interrupt structure, two pulse-width- modulation outputs, two UART and two DPTR, an on-chip oscillator and timing circuit. For system that requires extra capability the SM89T16R1 can be expanded using standard TTL compatible memory and logic. In addition, The SM89T16R1 has two software selectable modes of power saving - IDLE mode and POWER-DOWN mode. The IDLE mode freezes the CPU while allowing the RAM, timer, serial ports, and interrupt system to continue functioning. The POWER-DOWN mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative. The Power Management Mode (PMM) is useful for portable or battery-powered applications. This feature allows software to select a lower speed clock as the main time base.

Names and Functions
Power supply: +3.3V and +5V power supply pin during normal operations and power saving modes. Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to them become floating and can be used as high- impedance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external program and data memory. In this application, it uses strong internal pull-ups when emitting 1s. Port Pin Alternative function P0.0 AD0 P0.1 AD1 P0.2 AD2 P0.3 AD3 P0.4 AD4 P0.5 AD5 P0.6 AD6 P0.7 AD7 Port 1: An 8-bits bidirectional I/O port with internal pull-ups on all pins. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Alternate function of SM89T16R1 include: Port Pin Alternative function P1.0 T2: TIMER2 clock output P1.1 T2EX: TIMER2 reload/capture DIR. P1.2 RxD1: UART1 input P1.3 TxD1: UART1 output P1.4 PWM0: PWM channel 0 output INT2: rising edge trigger P1.5 PWM1: PWM channel 1 output #INT3: falling edge trigger P1.6 INT4: rising edge trigger P1.7 #INT5: falling edge trigger Reset: A high on this pin for two machine cycles while the oscillator is running resets the device. An internal resistor to VSS permits a power-on reset using only an external capacitor to VCC. Port 2: Port 2 is an 8-bits bidirectional I/O port with internal pull-ups. Port 2 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 2 pins that are externally being pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that uses 16-bits addresses (MOVX @DPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memory that uses 8-bits addresses (MOV @Ri), port 2 emits the contents of the P2 special function register. Port Pin Alternative function P2.0 A8 P2.1 A9 P2.2 A10 P2.3 A11 P2.4 A12/ADC0 P2.5 A13/ADC1 P2.6 A14/ADC2 P2.7 A15/ADC3

Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are externally being pulled low will source current because of the pull-ups. (See DC Electrical Characteristics: IIL). Port 3 also serves the special features.

In normal operation, ALE is emitted twice every machine cycle, and can be used for external timing or clocking. Note that one ALE pulse is skipped during each access to external data memory. Setting SFR SCONF.0 can disable ALE. With this bit set, ALE will be active only during a MOVX instruction. X32OUT: The 32.768KHz crystal output for RTC function. Program Store Enable: The read strobe to external program memory. When executing code from the external program memory, #PSEN is activated twice each machine cycle, except that two #PSEN activations are skipped during each access to external data memory. #PSEN is not activated during fetches from internal program memory. X32IN: The 32.768KHz crystal input for RTC function. External Access Enable: #EA must be externally held low to enable the device to fetch code from external program memory locations. If #EA is held high, the device executes from internal program memory. Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator circuits. Crystal 2: Output from the inverting oscillator amplifier.

The IDLE MODE supply current is measured with all output pins disconnected; XTAL1 driven with tr = tf = 5ns; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;/EA= Port0=VCC. 3. The POWER-DOWN MODE supply current is measured with all output pins disconnected; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect; /EA= Port0=VCC. 4. Port 1, 2, 3, and 4 sources a transition current when they are being externally driven from HIGH to LOW. The transition current reaches its maximum value when VIN is approximately 2V. 5. Capacities loading on port 0 and 2 may cause spurious noise to be superimposed on VOL of ALE and port 1, 3, and 4. The noise is due to external bus capacitance discharging into port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations. In the worst cases (capacities loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt trigger STROBE input.

Function Description
The SM89T16R1 is a High-Speed (4 clocks/machine cycle) stand-alone high-performance microcontroller designed for use in 3V/5V application, such as LCD monitor, instrumentation, or high-end consumer applications. In addition to the 80C51 standard functions, the device provides a number of dedicated hardware functions for these applications. The SM89T16R1 is a control-oriented CPU with on-chip program and data memory. It can be extended with external data memory up to 64K bytes. For system requiring extra capability, the SM89T16R1 can be enhanced by using external memory and peripherals. The SM89T16R1 has two software selectable modes of saving power consumption-IDLE and POWER-DOWN. The IDLE mode freezes the CPU while allowing the RAM, timer, serial ports and interrupt system to continue functioning. The POWER-DOWN mode save the RAM contents but freezes the oscillator causing all other chip functions to be inoperative. The POWER-DOWN mode can be terminated by H/W reset, or by any one of the six external interrupt or RTC function.
CPU
The CPU of SM89T16R1 is High-Speed 80C51. The structure of this CPU is shown as FIGURE 12. It contains Instruction Register (IR), Instruction Decoder, Program Counter (PC), Accumulator (ACC), B Register, and control logic. This CPU provides an 8-bits bi-direction bus to communicate with other blocks in the chip. The address and data are transferred through on the same 8-bits bus.

CPU Timing
The machine cycle consists of a sequence of 4 states, numbered S1 through S4. Only one-oscillator periods for each state time. Thus a machine cycle takes 4 oscillator periods. FIGURE 13 Shows relationships between oscillator, phase, and S1-S4.

Figure 13 Sequences and Phases
FIGURE 14 shows the fetch / execute sequences in states and phases for various kinds of instructions. Normally the program fetches are generated during each machine cycle, even if the instruction being executed doesn't require it. If the instruction being executed doesn't need more code bytes, the CPU simply ignores the extra fetch, and the PROGRAM COUNTER is incremented accordingly. Due to the reduced time for each instruction execution, both of the clocks edges are used for internal timing. Hence it is important that the duty cycle of the clock be as close to 50% as possible to avoid timing conflicts. The SM89T16R1 dose one op-code fetch per machine cycle. Therefore, in most of the instructions, the number of machine cycles needed to execute the instruction is equal to the number of bytes in the instruction. Of the 256 available op-codes, 128 of them are signal cycle instruction. See Figure14 shows the different cycle (A-D) instruction timing.

In standard 8032, the MOVX instructions take two machine cycles to execute. However in the SM89T16R1, the user has a facility to stretch the duration of this instruction from 2 machines cycle to 9 machines. The /RD and /WR strobe lines are also proportionately elongated. This gives the user flexibility in accessing both fast and slow peripherals without the use of external circuitry and with minimum software overhead. See FIGURE 15

Dual UART
Serial Port in the SM89T16R1 is a full duplex port. The SM89T16R1 provides the user with additional features such as the Frame Error Detection and the Automatic Address Recognition. The serial ports are capable of synchronous as well as asynchronous communication. In Synchronous mode the SM89T16R1 generates the clock and operates in a half duplex mode. In the asynchronous mode, full duplex operation is available. This means that it can simultaneously transmit and receive data. The transmit register and the receive buffer are both addressed as SBUF Special Function Register. However any write to SBUF will be to the transmit register, while a read from the receive buffer register. The serial port can operate in four different modes as described below.
Mode 0
This mode provides synchronous communication with external devices. In this mode serial data is transmitted and received on the RxD line. TxD is used to transmit the shift clock. The TxD clock is provided by the SM89T16R1 whether the device is transmitting or receiving. This mode is therefore a half duplex mode of serial communication. In this mode, 8 bits are transmitted or received per frame. The LSB is transmitted / received first. The baud rate is fixed at 1/12 or 1/4 of the oscillator frequency. This baud rate is determined at the SM2 bit (SCON.5). When this bit is set to 0, then the serial port runs at 1/12 of the clock. When set to 1, the serial port runs at 1/4 of the clock. This additional facility of programmable baud rate in mode 0 is the only difference between the standard 8051 and the SM89T16R1. The function block diagram is shown below. Data enters and leaves the Serial port on the RxD line. The TxD line is used to output the shift clock. The shift clock is used to shift data into and out of the SM89T16R1 and the device at the other end of the line. Any instruction that causes a write to SBUF will start the transmission. The shift clock will be activated and data will shifted out on the RxD pin till all 8 bits are transmitted. If SM2 = 1, then the data on RxD will appear 1 clock period before the falling edge of shift clock on TxD. The clock on TxD then remains low for 2 clock periods, and then goes high again. If SM2 = 0, the data on RxD will appear 3 clock periods before the falling edge of shift clock on TxD. The clock on TxD then remains low for 6 clock periods, and then goes high again. This ensures that at the receiving end the data on RxD line can either be clocked on the rising edge of the shift clock on TxD or latched when the TxD clock is low. The TI flag is set high following the end of transmission of the last bit. The serial port will receive data when REN is 1 and RI is zero. The shift clock (TxD) will be activated and the serial port will latch data on the rising edge of the shift clock. The external device should therefore present data on the falling edge on the shift clock. This process continues till all the 8 bits have been received. The RI flag is set following the last rising edge of the shift clock on TxD. This will stop reception, till the RI is cleared by software.

Mode 1
In mode 1, the full duplex asynchronous mode is used. Serial communication frames are made up of 10 bits transmitted on TxD and received on RxD. The 10 bits consist of a start bit (0), 8 data bits (LSB first), and a stop bit (1). On receive; the stop bit goes into RB8 in the SFR SCON. The baud rate in this mode is variable. The serial baud can be programmed to be 1/16 or 1/32 of the Timer 1 overflow. Since the Timer 1 can be set to different reload values, a wide variation in baud rates is possible. Transmission begins with a write to SBUF. The serial data is brought out on to TxD pin following the first rollover of divide by 16 counter. The next bit is placed on TxD pin following the next rollover of the divide by 16 counter. Thus the transmission is synchronized to the divide by 16 counter and not directly to the write to SBUF signal. After all 8 bits of data are transmitted the stop bit is transmitted. The TI flag is set after the stop bit has been put out on TxD pin. This will be at the 10th rollover of the divide by 16 counter after a write to SBUF. Reception is enabled only if REN is high. The serial port actually starts the receiving of serial data, with the detection of the falling edge on the RxD pin; the 1-to-0 detector continuously monitors the RxD line, sampling it at the rate of 16 times the selected baud rate. When a falling edge is detected, the divide by 16 counter is immediately reset. This helps to align the bit boundaries with the rollovers of the divide by 16 counter. The 16 states of the counter effectively divide the bit time into 16 slices. The bit detection is done on a best of three bases. The bit detector samples the RxD pin, at the 8th, 9th and 10th counter states. By using a majority 2 or 3 voting system, the bit value is selected. This is done to improve the noise rejection feature of the serial port. If the first bit detected after the falling edge of RxD pin is not 0, then this indicates an invalid start bit, and the reception is immediately aborted. The serial port again looks for a falling edge in the RxD line. If a valid start bit is detected, then the rest of the bits are also detected and shifted into the SBUF. After shifting in 8 data bits, there is one more shift to do, after which the SBUF and RB8 are loaded and RI is set. However certain conditions must be met before the loading and setting of RI can be done. RI must be 0 and Either SM2 = 0, or the received stop bit = 1. If these conditions are met, then the stop bit goes to RB8; the 8 data bits go into SBUF and RI is set. Otherwise the received frame may be lost. After the middle of the stop bit, the receiver goes back to looking for a 1-to-0 transition on the RxD pin.

Mode 2
This mode uses a total of 11 bits in asynchronous full-duplex communication. The functional description is shown in the figure below. The frame consists of one start bit (0), 8 data bits (LSB first), a programmable 9th bit (TB8) and a stop bit (0). The 9th bit received is put into RB8. The baud rate is programmable to 1/32 or 1/64 of the oscillator frequency, which is determined by the SMOD bit in PCON SFR. Transmission begins with a write to SBUF. The serial data is brought out on to TxD pin following the first rollover of the divide by 16 counter. Thus the transmission is synchronized to the divide by 16 counter, and not directly to the write to SBUF signal. After all 9 bits of data are transmitted the stop bit is transmitted. The TI flag is set after the stop bit has been put out on TxD pin. This will be at the 11th rollover of the divide by 16 counter after a write to SBUF. Reception is enabled only if REN is high.

Mode 3
This mode is similar to Mode 2 in all respects; expect that the baud rate is programmable. The user must first initialize the Serial related SFR SCON before any communication can take place. This involves selection of the Mode and Baud rate. The Timer 1 should also be initialized if modes 1 and 3 are used. In all four modes, transmission is started by any instruction that uses SBUF as a destination register. Reception is initiated in Mode 0 by the condition RI = 0 and REN = 0. This will generate a clock on the TxD pin and shift in 8 bits on the RxD pin. Reception is initiated in the other modes by the incoming start bit if REN = 1. The external device will start the communication by transmitting the start bit.
Pulse Width Modulation (PWM)
The PWM output pins are P1.4 and P1.5. The PWM clock is {Fosc/ (2xDivider)}, the PWM output frequency is {(PWM clock)/32} at 5 bits resolution and {(PWM clock)/256} at 8 bits resolution. The PWM SFR is shown as below:

Power Saving Mode
The SM89T16R1 has several features that help the user to control the power consumption of the device. The powers saving features are basically the Power Down mode, Economy mode and the Idle mode of operation.
Idle Mode
The user can put the device into idle mode by writing 1 to the bit PCON.0. The instruction that sets the idle bit is the last instruction that will be executed before the device goes into Idle Mode. In the Idle Mode, the clock to the CPU is halted, but not to the Interrupt, Timer and Serial port blocks. This forces the CPU state to be frozen; the Program counter, the Stack Pointer, the Program Status Word, the Accumulator and the other registers hold their contents. The ALE and PSEN pins are held high during the idle state. The port pins hold the logical states they had at the time idle was activated. The idle mode can be terminated in two ways. Since the interrupt controller is still active, the activation of any enabled interrupt can wake up the processor. This will automatically clear the idle bit, terminate the idle mode, and the Interrupt Service Routine (ISR) will be executed. After the ISR, execution of the program will continue from the instruction that put the device into idle mode. The Idle mode can also be exited by activating the reset. The device can be put into reset either applying a high on the external RST pin or a Power on reset condition. The external reset pin has to be held high for at least two machine cycles to be recognized as a valid reset. In the reset condition the program counter is reset to 0000H and all the SFRs are set to the reset condition. Since the clock is already running there is no delay and execution start immediately. When the SM89T16R1 is exiting from an idle mode with a reset, the instruction following the one that put the device into idle mode is not executed. So there is no danger of unexpected writes.

The Power Down Wake Up (PDWU) function
The device can be put into Power Down mode by writing 1 to bit PCON.1. The instruction that does this will be the last instruction to be executed before the device goes into Power Down mode. In the Power Down mode, all the clocks are stopped and the device comes to a halt. All activity is completely stopped and the power consumption is reduced to the lowest possible value. In this state the ALE and PSEN pins are pulled low. The port pins output the values held by their respective SFRs. The SM89T16R1 will exit the Power Down mode with a reset or by a RTC (Real Time Clock) interrupt or by an external interrupts pin enabled as level detects. 1. An external reset can be used to exit the Power Down state. The high on RST pin terminates the Power Down mode, and restarts the clock. The program execution will restart from 0000H. 2. An external interrupt pin and RTC interrupt can be used to exit the Power Down state when the external interrupt or RTC interrupt actives and provided the corresponding interrupt is enabled, while the global enable (EA) bit is set and the external input has been set to a level detect mode or RTC interrupt set. If these conditions are met, then the low level on the external pin or RTC interrupt re-starts the oscillator. Then device executes the interrupt service routine for the corresponding external interrupt or RTC interrupt. After the interrupt service routine is completed, the program execution returns to the instruction after the one that put the device into Power Down mode and continues from there.

Power Management Mode (PMM)
Power Management Mode offers a complete scheme of reduced internal clock speeds that allow the CPU to run software but to use substantially less power. Normally, during default operation, the SM89T16R1 uses 4 clocks per machine cycle. Thus the instruction cycle (machine cycle clock) rate is clock/4. At 16 MHz crystal speed, the instruction cycle speed is 4 MHz. In Power Management Mode (PMM) the instruction cycle (machine cycle clock) rate is clock/1024. At same 16 MHz crystal speed, the instruction cycle speed is 15.6 KHz. The operation current is down from 20mA to 5mA. See Table 5.

Economy Mode
The power consumption of microcontroller relates to operating frequency. The SM89T16R1 offers an Economy mode to reduce the internal clock rate dynamically without external components. By default, one machine cycle needs 4 clocks. In Economy mode, software can select 4, 64, or 1024 clocks per machine cycle. It keeps the CPU operating a acceptable speed but eliminates the power consumption. In the Idle mode, the clock of the core logic is stopped, but all clocked peripherals such as timer are still running at a rate of clock/4. In the Economy mode, all clocks peripherals run at the same reduced clocks rate as in core logic. So the Economy mode may provide lower power consumption than Idle mode. Software invokes the Economy mode by setting the appropriate bits in the SFRs. Setting the bits CD0 (PMR.6), CD1 (PMR.7) decides the instruction cycle rate as below:

Test Internal RC oscillator and External crystal switching EXIF ($91H)
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 IE5 IE4 IE3 IE2 XT/~RG IE5: When set to `1', external interrupt 5 flag. IE4: When set to `1', external interrupt 4 flag. IE3: When set to `1', external interrupt 3 flag. IE2: When set to `1', external interrupt 2 flag. XT/~RG: When set to `1', the MCU used External Crystal. When clear to `0', the MCU used Internal RC Oscillator This selection of instruction rate is going to take effect after a delay of one instruction cycle. Switching to divide by 64 or 1024 mode must first go from divide by 4 modes. This means software cannot switch directly between clock/64 and clock/1024 mode. The CPU has to return clock/4 mode first, then go to clock/64 or clock/1024 mode. The SM89T16R1 allows the user to use internal RC oscillator instead of external crystal. Setting the XT/~RG bit (EXIF.3) selects the crystal or RC oscillator as the clock source. When invoking RC oscillator in Economy mode, software may set the XTOFF bit to turn off the crystal amplifier for saving power. The CPU would run at the clock rate of approximately 2-4 MHz divided by 4, 64 or 1024. The RC oscillator is not precise so that cannot be invoked to the operation that needs the accurate time-base such as serial communication. If crystal amplifier is disabled and RC oscillator is present clock source, software must first clear the XTOFF bit to turn on crystal amplifier before switch to crystal operation.
