8-bit Micro-controller

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.
