General Description

The 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

The 87C552 has the same instruction set as the 80C51.

The 87C552 contains a 8k × 8 non-volatile EPROM, a 256 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and pare latches, a 15-source, four-priority-level, nested interrupt structure, an 8-input ADC, a dual DAC pulse width modulated interface, two serial interfaces (UART and I2C-bus), a “watchdog” timer and on-chip oscillator and timing circuits.

Key Features

  • 80C51 central processing unit.
  • 8k × 8 EPROM expandable externally to 64k bytes.
  • An additional 16-bit timer/counter coupled to four capture registers and three compare registers.
  • Two standard 16-bit timer/counters.
  • 256 × 8 RAM, expandable externally to 64k bytes.
  • Capable of producing eight synchronized, timed outputs.
  • A 10-bit ADC with eight multiplexed analog inputs.
  • Fast 8-bit ADC option.
  • Two 8-bit resolution, pul.
