3 / 24 page 1996 Nov 25 3 Philips Semiconductors Product specification 8-bit microcontroller with I2C-bus interface PCF84C00 1 FEATURES • Manufactured in silicon gate CMOS process • 8-bit CPU, RAM, I/O in a single 28-lead or 56-lead package • ‘Piggy-back’ and ROM-less versions, external program memory • 256 × 8 RAM • 20 quasi-bidirectional I/O port lines • Two test inputs, one of which is also the external interrupt input • Three single-level vectored interrupts: – external – timer/event counter –I2C-bus • I2C-bus interface for serial data transfer on two lines (serial I/O data via an existing port line and clock via a dedicated line) • 8-bit programmable timer/event counter • Clock frequency range: 100 kHz to 10 MHz • Over 80 instructions (similar to those of the MAB8048) all of 1 or 2 cycles • Single supply voltage (2.5 to 5.5 V) • Stop and Idle modes • Power-on reset circuit • Operating temperature range: −40 to +85 °C. 2 GENERAL DESCRIPTION This data sheet details the specific properties of the PCF84C00. The shared properties of the PCF84CxxxA family of microcontrollers are described in the “PCF84CxxxA family” data sheet, which should be read in conjunction with this publication. The PCF84C00 has 20 quasi-bidirectional I/O lines, an I2C-bus serial interface, a single-level vectored interrupt structure, an 8-bit timer/event counter and on-chip clock oscillator and clock circuits. This efficient controller also performs well as an arithmetic processor. It has facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set is similar to the MAB8048 and is a sub-set of that listed in the “PCF84CxxxA family” data sheet. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION PCF84C00B − Non-standard 28-lead ‘piggy-back’ package with 28-pin EPROM socket on top. Bottom ‘footprint’ and pinning as DIP 28, version SOT117-1. The SOT117-1 information provided in Chapter “Package Outlines” is correct in these respects, but not for the physical size of the PCF84C00B, which is larger than the SOT117-1 package. − PCF84C00T VSO56 Plastic very small outline package; 56 leads. SOT 190-1 |
