MEGAWIN

General Description
The MG86FE/L508 is a single-chip microcontroller based on a high performance 1-T architecture 80C51 CPU that executes instructions in 1~6 clock cycles (about 6~7 times the rate of a standard 8051 device), and has an 8051 compatible instruction set. Therefore at the same performance as the standard 8051, the MG86FE/L508 can operate at a much lower speed and thereby greatly reduce the power consumption.
The MG86FE/L508 has 8K bytes of embedded Flash memory for code and data. The Flash memory can be programmed either in serial writer mode (via ICP, In-Circuit-Programming) or in ISP (In-System Programming) mode. And, it also provides the In-Application Programming (IAP) capability. ICP and ISP allow the user to download new code without removing the microcontroller from the actual end product; IAP means that the device can write non-volatile data in the Flash memory while the application program is running. There needs no external high voltage for programming due to its built-in charge-pumping circuitry.
