DESCRIPTION

The 8XC528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC528 has the same instruction set as the 80C51. Three versions of the derivative exist: ROM

multi-source, two-priority-level, nested interrupt structure, two serial interfaces (UART and I2C-bus), and on-chip oscillator and timing circuits. In addition, the 8XC528 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.

FEATURES

8 ROM (83C528) ROMless (80C528) RAM Memory addressing capability 64k ROM and 64k RAM Three 16-bit counter/timers On-chip watchdog timer with oscillator Full duplex UART I2C serial interface Four 8-bit I/O ports

in a separate data sheet) This device provides architectural enhancements that make it applicable in a variety of applications in consumer, telecom and general control systems, especially in those systems which need large ROM and RAM capacity on-chip. The 8XC528 contains 8 ROM 8 RAM, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the a 16-bit timer (identical to the timer 2 of the 80C52), a watchdog timer with a separate oscillator, a
