SM5964A 8-Bit Micro-controller With 64KB ISP Flash & TWSI & PWM & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.3 SM5964A 10/2006 4 Pin Description MNEMONIC PDIP 40 pin PQFP 44 Pin PLCC 44 pin Names and Functions VDD 40 38 44 Power supply: +3.3V 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. 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 SM5964A include: Port Pin Alternative function P1.0 T2: TIMER2 clock output P1.1 T2EX:TIMER2 reload/capture DIR. P1.2 PWM0:PWM channel 0 output P1.3 PWM1:PWM channel 1 output P1.6 SCL:TWSI bus clock P1.7 SDA:TWSI bus data 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. P3.0 – P3.7 10,11,12,13 14,15,16,17 5,7,8,9, 10,11,12,13 11, 13,14,15, 16,17,18,19 Port 3: Port 3 is an 8-bits bidirectional I/O port with internal pull-ups. 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. Port Pin Alternative function P3.0 RxD UART input P3.1 TxD UART output P3.2 #EX0 external interrupt 0 P3.3 #EX1 external interrupt 1 P3.4 T0: Timer 0 external input P3.5 T1: Timer 1 external input P3.6 #WR External data memory write strobe P3.7 #RD External data memory read strobe |
