INTEGRATED CIRCUITS 89C536/89C538 80C51 8-bit microcontroller family 16K/64K/512 FLASH Preliminary specification Supersedes data of 1997 Dec 02 IC20 Data Handbook 1998 Apr 24 Philips Semiconductors Philips Semiconductors Preliminary specification 80C51 8-bit microcontroller family 16K/64K/512 FLASH 89C536/89C538 DESCRIPTION The 89C536/89C538 are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family.
All the devices have the same instruction set as the 80C51.
The devices also have four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, two-priority-level, nested interrupt structure, UART and on-chip oscillator and timing circuits.
For systems that require extra data memory capability up to 64k bytes, each can be expanded using standard TTL-compatible memories and logic.
The 89C536/89C538 contain a non-volatile FLASH program memory (16k bytes in the 89C536, and 64k bytes in the 89C538).
The devices have 512 bytes of RAM data memory.
FEATURES • 80C51 Central Processing Unit • 16k × 8 (89C536) or 64k × 8 (89C538), FLASH EPROM Program Memory • 512 × 8 RAM, externally expandable to 64k × 8 Data Memory • Three 16-bit counter/timers • Up to 3 external interrupt request inputs • 6 interrupt sources with 2 priority levels • Four 8-bit I/O ports • Full-duplex UART • Power control modes – Idle mode – Power down mode, with wakeup from power down using external interrupt • 44-pin PLCC and QFP packages ORDERING INFORMATION PART NUMBER P89C536NBA A P89C536NBB B P89C538NBA A P89C538NBB B MEMORY SIZE 16k bytes 16k bytes 64k bytes 64k bytes TEMPERATURE RANGE (°C) AND PACKAGE 0 to +70, 44-pin Plastic Leaded Chip Carrier 0 to +70, 44-pin Plastic Quad Flat Package 0 to +70, 44-pin Plastic Leaded Chip Carrier 0 to +70, 44-pin Plastic Quad Flat Package FREQ.
