PHILIPS 89C535/89C536/89C538 CMOS single-chip 8-bit microcontrollers with FLASH program memory handbook

Update: 30 September, 2023

89C535/89C536/89C538 are single-chip 8-bit microcontrollers manufactured by Philips 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 89C535/89C536/89C538 contain a non-volatile FLASH EPROM program memory (8K bytes in 89C535, 16k bytes in the 89C536, and 64k bytes in the 89C538). The devices have 512 bytes of RAM data memory.
