The 89C536/89C538 are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family. The devices 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.
This document is a preliminary specification datasheet for the Philips 89C536/89C538 family of single-chip 8-bit microcontrollers. These devices are derivatives of the 80C51 family and feature an advanced CMOS process with non-volatile FLASH program memory (16k bytes for the 89C536 and 64k bytes for the 89C538) and 512 bytes of RAM data memory.
The operating temperature range for these specific part numbers is 0 to +70 degrees Celsius.
The devices have 512 bytes of RAM data memory.
The P89C536NBB model contains 16k bytes of FLASH EPROM program memory.
