General Description
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.
The operation frequency reaches at 24 MHz. An user can apply a crystal oscillator for the
oscillating source, or alternatively uses the built in 6 MHz RC oscillator to save system cost.
The built in high performance 10-bit Analog-to-Digital Converter make it easy to sensing the
environment or implement a set of scan keys in low cost.
The UART and SPI interfaces make the device convenient to communicate with the peripheral
component: talking to a personal computer via RS-232 port, or communicating with a serial
memory.
The Pulse-Width-Modulator (PWM) mode in Programmable Counter Array (PCA) makes the
device to drive the peripheral step motor or LED in least cost.
The MPC82x54A is really the most efficient MCU adapted for simple control, such as:
electronic scales, remote controller, security encoder/decoder, and user interface controller.
