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.
