11 / 76 page  1997 Dec 15 11 Philips Semiconductors Product specification 8-bit microcontrollers P83C524; P80C528; P83C528 7.2 Pin description Table 1 Pin description for P83C524, P80C528 and P83C528; see note 1 SYMBOL PIN DESCRIPTION SOT 129-1 SOT 187-2 SOT 307-2 P1.0 −P1.7 1 to 8 2 −9 (1 n.c.) 1 −3, 40 −44 (39 n.c.) Port 1: 8-bit quasi-bidirectional I/O Port. Port 1 can sink/source one TTL (= 4 LSTTL) input. It can drive CMOS inputs without external pull-ups, except P1.6 and P1.7 which have open drain outputs. Port 1 alternative functions: T2 1240 P1.0 Timer/event counter 2 external event counter input (falling edge triggered) T2EX 2 3 41 P1.1 Timer/event counter 2 capture/reload trigger or external interrupt 2 input (falling edge triggered) SCL 7 8 2 P1.6 I2C-bus Serial Port clock line SDA 8 9 3 P1.7 I2C-bus Serial Port data line. RST 9 10 4 RESET: a HIGH level on this pin for two machine cycles while the oscillator is running, resets the device. An internal pull-down resistor permits power-on reset using only a capacitor connected to VDD. After a WDT overflow this pin is pulled HIGH while the internal reset signal is active. P3.0 −P3.7 10−17 11, 13 −19 (12 n.c.) 5, 7 −13 (6 n.c.) Port 3: 8-bit quasi-bidirectional I/O Port with internal pull-ups. Port 3 can sink/source one TTL (= 4 LSTTL) input. It can drive CMOS inputs without external pull-ups. Port 3 alternative functions: RXD/data 10 11 5 P3.0 Serial Port data input (asynchronous) or data input/output (synchronous) TXD/clock 11 13 7 P3.1 Serial Port data output (asynchronous) or clock output (synchronous) INT0 12 14 8 P3.2 external interrupt 0 or gate control input for timer/event counter 0 INT1 13 15 9 P3.3 external interrupt 1 or gate control input for timer/event counter 1 T0 14 16 10 P3.4 external input for timer/event counter 0 T1 15 17 11 P3.5 external input for timer/event counter 1 WR 16 18 12 P3.6 external data memory write strobe RD 17 19 13 P3.7 external data memory read strobe. The generation or use of a Port 3 pin as an alternative function is carried out automatically by the P83C528 provided the associated Special Function Register (SFR) bit is set HIGH. XTAL2 18 20 14 Crystal input 2: output of the inverting amplifier that forms the oscillator. This pin left open-circuit when an external oscillator clock is used (see Figures 22 and 23). |
