Device Overview

Summary

High performance flash version of the 80C51 8-bit microcontrollers. It contains a 32-KB flash memory block for program and data.

Flash memory can be programmed either in parallel or serial mode using ISP or software. The programming voltage is internally generated from the standard VCC pin.

This device retains all features of the 80C52 with 256 bytes of internal RAM, a 10-source 4-level interrupt controller, and three timer/counters.
