General Description
MPC89x51A is a single-chip 8-bits micro-controller with the instruction sets fully compatible with
industrial-standard 80C51 series microcontroller.
There is 4 Kbytes flash memory embedded for application program, 11 Kbytes
data flash
shared
by
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 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.
MPC89x51A is built with four 8-bits I/O ports, one 4-bits I/O ports, three 16-bits 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
MPC89x51A
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.
