80C51 8-bit microcontroller family

4K/128 OTP/ROM/ROMless, 8 channel 8 bit A/D, watchdog timer

Product specification

80C550/83C550/87C550

DESCRIPTION

The Philips 8XC550 is a high-performance microcontroller fabricated

with Philips high-density CMOS technology. This Philips CMOS

technology combines the high speed and density characteristics of

HMOS with the low power attributes of CMOS. Philips epitaxial

substrate minimizes latch-up sensitivity. The CMOS 8XC550 has the

same instruction set as the 80C51.

The 8XC550 contains a 4k × 8 EPROM (87C550)/ROM

(83C550)/ROMless (80C550 has no program memory on-chip), a

128 × 8 RAM, 8 channels of 8-bit A/D, four 8-bit ports (port 1 is input

only), a watchdog timer, two 16-bit counter/timers, a seven-source,

two-priority level nested interrupt structure, a serial I/O port for either

multi-processor communications, I/O expansion or full duplex UART,

and an on-chip oscillator and clock circuits.

In addition, the 8XC550 has two software selectable modes of

power reduction—idle mode and power-down mode. The idle mode

freezes the CPU while allowing the RAM, timers, serial port, and

interrupt system to continue functioning. The power-down mode

saves the RAM contents but freezes the oscillator, causing all other

chip functions to be inoperative.
