General Description
MPC89x52A is a single-chip 8-bit microcontroller with the instruction sets fully compatible with
industrial-standard 80C51 series microcontroller.
There is 8 Kbytes flash memory embedded for application program, 7 Kbytes 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.
There are 512 bytes on-chip RAM embedded that are provided to implement wide field
applications. The user can configure the device to run in 12 clocks per machine cycle, or 6
clocks per machine cycle to achieve twice performance.
MPC89x52A is built with four 8-bit I/O ports, one 4-bit I/O ports, three 16-bit timer/counters, an
eight-source, four-priority-level interrupt structure, an enhanced UART and on-chip crystal oscillator. It
was fabricated in advanced embedded flash CMOS technology.
Excellent flash-endurance, flash-retention, and code-protecting security make MPC89x52A as an
excellent microcontroller.
If the supply voltage of the device is lower than 3.7V/2.4V (Operate in the 5V/3V).The device can
automatically go to reset, and we have named it the Low-Voltage-Reset.
