4 / 35 page SyncMOS Technologies International, Inc. SM89T16R1 8-Bits Micro-controller With 64KB Flash ROM & 1KB RAM & Two UART & RTC & ADC & PWM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.1 SM89T16R1 08/2006 4 Pin Description MNEMONIC DIP 40 pin PQFP 44 Pin PLCC 44 pin Names and Functions VDD 40 38 44 Power supply: +3.3V and +5V power supply pin during normal operations and power saving modes. P0.0 – P0.7 39,38,37,36 35,34,33,32 37,36,35,34 33,32,31,30 43,42,41,40 39,38,37,36 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 P1.0 – P1.7 1,2,3,4, 5,6,7,8 40,41,42,43, 44,1,2,3 2,3,4,5, 6,7,8,9 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 RST 9 4 10 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. P2.0 – P2.7 21,22,23,24, 25,26,27,28 18,19,20,21 22,23,24,25 24,25,26,27, 28,29,30,31 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.
