NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section of this specification is not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS  unless otherwise noted.



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:
*83C528 - 32k bytes mask programmableROM
*80C528 - ROMless version of the83C528
*87C528 - 32k bytes EPROM (described In a separate data sheet)
80C528 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 a 32k * 8 ROM(83C528), a 512 * 8 RAM, four 8-bit I/Oports, two 16-bit timer/event counters(identical to the timers of the 80C51), a 16-bittimer (identical to the timer 2 of the 80C52), a watchdog timer with a separate oscillator, amulti-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 softwareselectable 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.
