8-bit microcontroller with A/D converter and 64-Kbyte Flash. 2-Kbyte RAM, 2-Kbyte EEPROM, SPI. Power Fail Detect (no need for external brown- out). Pinout compatible with T89C51AC2.
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.
