General Description
PC89x54A is a single-chip 8-bit microcontroller with the instruction sets fully compatible with
industrial-standard 80C51 series microcontroller.
There is 16 Kbytes flash memory embedded for application program. A 47 Kbytes
data flash
is
shared by both In-System Programming code and In-Application-Programming code.
In-System-Programming and In-Application-Programming allow the users to download new code
or data while the microcontroller sits in the running state.
There are 1280 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.
MPC89x54A 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
MPC89x54A
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 the Low-Voltage-Reset
