Hot-selling and scarce P80C652EBA CMOS single-chip 8-bit microcontrollers PLCC spot stock

Product Descriptions

The P80C652/83C652 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The80C652/83C652 has the same instruction set as the 80C51 . Three versions of the derivative exist:

83C652 — 8k bytes mask programmable ROM

80C652 — ROMless version

87C652 — EPROM version (described in a separate chapter)

This device provides architectural enhancements that make it applicable in a variety of applications for general control systems. The 8XC652 contains a non-volatile8k ×8 read-only program memory, a volatile256 ×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 I2 C interface, UART and on-chip oscillator and timing circuits. For systems that require extra capability, the8XC652 can be expanded using standard TTL compatible memories and logic.​

The device also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instructions:49 one-byte,45 two-byte and 17 three-byte. With a 16(24)MHz crystal, 58% of the instructions are executed in 0.75(0.5)µs and 40% in 1.5(1)µs. Multiply and divide instructions require 3(2)µs.
