Description

The P80C652/83C652 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 80C652/83C652 has the same instruction set as the 80C51. Three versions of the derivative exist:

83C652 - 8k bytes mask programmable ROM

80C652 - ROMless version87C652 - EPROM version (described in a separate chapter)

P80C652/83C652 provide architectural enhancements that make it applicable in a variety of applications for general control systems. The 8XC652 contains a non-volatile 8k * 8 read-only program memory, a volatile 256 * 8 read/write data memory, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51), a multi-source, two-priority-level, nested interrupt structure, an I2C interface, UART and on-chip oscillator and timing circuits. For systems that require extra capability, the 8XC652 can be expanded using standard TTL compatible memories and logic.
