P89C536 Datasheet 80c51 8-bit Microcontroller Family 16k/64k/512 Flash

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS 89C536/89C538 80C51 8-bit microcontroller family 16K/64K/512 FLASH Preliminary specification Supersedes data of 1997 Dec 02 IC20 Data Handbook 1998 Apr 24 Philips Semiconductors Philips.

General Description

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-source, two-priority-level, nested interrupt structure, UART and on-chip oscillator and timing circuits.

Key Features

  • 80C51 Central Processing Unit.
  • 16k × 8 (89C536) or 64k × 8 (89C538), FLASH EPROM Program Memory.
  • 512 × 8 RAM, externally expandable to 64k × 8 Data Memory.
  • Three 16-bit counter/timers.
  • Up to 3 external interrupt request inputs.
  • 6 interrupt sources with 2 priority levels.
  • Four 8-bit I/O ports.
  • Full-duplex UART.
  • Power control modes.
  • Idle mode.
  • Power down mode, with wakeup from power down using ext.
