Overview
IS89C52 IS89C52 CMOS SINGLE CHIP 8-BIT MICROCONTROLLER with 8-Kbytes of FLASH ISSI NOVEMBER 1998 GENERAL DESCRIPTION ISSI® ® FEATURES • 80C51 based architecture • 8-Kbytes of on-chip Reprogrammable Flash Memory • 256 x 8 RAM • Three 16-bit Timer/Counters • Full duplex serial channel • Boolean processor • 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 • Eight interrupt sources • Most instructions execute in 0.
3 µs • CMOS and TTL compatible • Maximum speed: 40 MHz @ Vcc = 5V • Industrial temperature available • Packages available: – 40-pin DIP – 44-pin PLCC – 44-pin PQFP The ISSI IS89C52 is a high-performance microcontroller fabricated using high-density CMOS technology.
The CMOS IS89C52 is functionally compatible with the industry standard 80C51 microcontrollers.
The IS89C52 is designed with 8-Kbytes of Flash memory, 258 x 8 RAM; 32 programmable I/O lines; a serial I/O port for either multiprocessor communications, I/O expansion or full duplex UART; three 16-bit timer/counters; an eight-source, two-priority-level, nested interrupt structure; and an on-chip oscillator and clock circuit.
The IS89C52 can be expanded using standard TTL compatible memory.
