89C538 Datasheet CMOS single-chip 8-bit microcontrollers with FLASH program memory

Manufacturer: NXP Semiconductors

General 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.
