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

1997 Jun 05
DESCRIPTION
The 89C535/89C536/89C538 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 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.
