MPC89E52A is a single-chip 8-bit micro-controller with the instruction sets, which is fully

compatible with industrial-standard 80C51 series microcontroller.

There is 8K bytes flash memory embedded for application program, 7K bytes data flash

shared by In-System Programming code, and In-Application-Programming code.

In-System-Programming and In-Application-Programming allows the users to download new

code or data while the microcontroller sits in the running state.
