IC89C54/58/64 CMOS SINGLE CHIP 8-BIT MICROCONTROLLER with 16/32/64-Kbytes of FLASH FEATURES • 80C52 based architecture • 16K/32K/64K Byte Flash Memory with fast- pulse programming algorithm • 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 Program Memory and 64K Data Memory • 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 • Packages available: – 40-pin DIP – 44-pin PLCC – 44-pin PQFP GENERAL DESCRIPTION IC89C54, IC89C58, IC89C64 are members of ICSI embedded microcontroller family. The IC89C54/58/64 uses the same powerful instruction set, has the same architecture, and is pin-to-pin compatible with standard 80C52 controller devices. IC89C54/58/64 are just changed internal Flash size, other features are same as standard IC89C52. The IC89C54/58/64 contains a 16K/32K/64K x 8 Flash; a 256 x 8 RAM; 32 I/O lines for either multi-processor communications; I/O expansion or full duplex UART; three 16-bit timers/counters; an eight-source, two-priority-level, nested interrupt structure; and on chip oscillator and clock circuit. The IC89C54/58/64 can be expanded using standard TTL compatible memory. Figure 1.
