General Description

MPC89x515A  is  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.    

MPC89x515A  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 MPC89x515A 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.
