Product Summary

The AT89C51ED2-UM is an 8-bit microcontroller. It contains a 64－Kbyte Flash memory block for code and for data. The 64－Kbytes Flash memory can be programmed either in parallel mode or in serial mode with the ISP capability or with software. The programming voltage is internally generated from the standard VCC pin. The AT89C51ED2-UM retains all of the features of the Atmel 80C52 with 256 bytes of internal RAM, a 9－source 4－level interrupt controller and three timer/counters. The AT89C51ED2-UM provides 2048 bytes of EEPROM for nonvolatile data storage. In addition, the AT89C51ED2-UM has a Programmable Counter Array, an XRAM of 1792 bytes, a Hardware Watchdog Timer, SPI interface, Keyboard, a more versatile serial channel that facilitates multiprocessor communication (EUART) and a speed improvement mechanism (X2 Mode).
