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. Enhanced 8-bit Microcontroller with 64KB Flash Memory AT89C51AC3 |
