Product Summary

The MPC82E54AE2 is a single-chip 8-bit micro-controller with instruction sets fully compatible with industrial-standard 80C51 series microcontroller. There is an excellent MCU kernel built in the MPC82E54AE2 compared to general 80C51 MCUs those take twelve oscillating cycles to finish an instruction, and this unique device could take only one oscillating cycle to finish one instruction. The MPC82E54AE2 is really the most efficient MCU adapted for simple control, such as: electronic scales, remote controller, security encoder/decoder, and user interface controller.
