MG87FE/MG87FL52,pdf datasheet

MG87FE/L52 is a single-chip 8 bits microcontroller with the instruction sets fully compatible with industrial-standard 80C51 series microcontroller. 8K bytes flash memory and 256 bytes RAM has been embedded to provide wide field application. In-System-Programming and In-Application-Programming allow the users to download new code or data while the microcontroller sits in the application. This device executes one machine cycle in 6 clock or 12 clock cycles. MG87FE/L52 has 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, on-chip crystal oscillator.
Excellent flash-endurance, flash-retention, and code-protecting security make MG87FE/L52 as an excellent micro-controller.
