DESCRIPTION
The Philips 8XC453 is an I/O expanded single-chip microcontroller fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes latch-up sensitivity.
The 8XC453 is a functional extension of the 87C51 microcontroller with three additional I/O ports and four I/O control lines. The 8XC453 is available in 68-pin LCC packages. Four control lines associated with port 6 facilitate high-speed asynchronous I/O functions.
The 87C453 includes an 8k × 8 EPROM, a 256 × 8 RAM, 56 I/O lines, two 16-bit timer/counters, a seven source, two priority level, nested interrupt structure, a serial I/O port for either a full duplex UART, I/O expansion, or multi-processor communications, and on-chip oscillator and clock circuits.
