89C536 Datasheet - NXP

89C536 - 80C51 8-bit microcontroller family 16K/64K/512 FLASH

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 devices also have four 8-bit I/O ports, three 16-bit timer/event counters, a multi-s.
