AT89C51RD2
AT89C51ED2
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
CC
pin.
