Description
The AT89C51AC3 is a high performance Flash version of the 80C51 single chip 8-bit
microcontrollers.
In X2 mode a maximum external clock rate of 20 MHz reaches a 300 ns cycle time.
Besides the AT89C51AC3 provides 64K Bytes of Flash memory including In-System
Programming (ISP) and IAP, 2K Bytes Boot Flash Memory, 2K Bytes EEPROM and
2048 byte ERAM.
Primary attention is paid to the reduction of the electro-magnetic emission of
AT89C51AC3.
