a single-chip 8-bit
microcontroller with the
instruction sets fully compatible with industrial-standard
80C51 series microcontroller.
There is 63 Kbytes flash memory
embedded for application program, which is shared with In-System Programming
code. In-System-Programming allows
the users to
download new code 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.
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.
flash-retention, and code-protecting security make MPC89x515A as an excellent
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.
