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 80C65.
