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 89C536/89C538 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 89C536/89C538 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.
