Hot-selling and scarce MPC82E54AS 8-bit micro-controller SOP20 spot stock

Product Descriptions

MPC82x54A 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 this device 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.

There is 15.5 Kbytes flash memory embedded which could be used as program or data. Also the  In-System  Programming and  In-Application  Programming mechanisms are supported. The data endurance of the embedded flash gets over 20,000 times, and 21 years data retention is guaranteed.
