Description

AT89C51RD2/ED2 is high performance CMOS Flash version of the 80C51 CMOS sin-

gle chip 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 V_CCpin.
