IC89C52(51)A

CMOS SINGLE CHIP

8-BIT MICROCONTROLLER

with 8(4)-Kbytes of FLASH

FEATURES

GENERAL DESCRIPTION

The ICSI IC89C52(51)A is a high-performance micro-

controller fabricated with high-density CMOS technology.

The CMOS IC89C52A is functionally compatible with the

NMOS Intel 8052(51), Philips’ 80C52(51) micro controller.

• 80C52(51) based architecture

• 8(4)-Kbytes Flash memory with fast-pulse

programming algorithm and software protection

• 256 x 8 RAM (128x8 RAM)

• Three (Two)16-bit Timer/Counters

• Full duplex serial channel

• Boolean processor

The IC89C52(51)A contains a 8K (4K) x 8 Flash; a 256

x 8 RAM (128 x 8 RAM); 32 I/O lines for either multi-

processor communications; I/O expansion or full duplex

UART; three (two) 16-bit timers/counters; a six-source

(five-source), two-priority-level, nested interrupt structure;

and on chip oscillator and clock circuit. The IC89C52(51)

AcanbeexpandedusingstandardTTLcompatiblememory.

• Four 8-bit I/O ports, 32 I/O lines

• Memory addressing capability

– 64K ROM and 64K RAM

• Program memory lock

– Lock bits (3)

• Power save modes:

– Idle and power-down
