AT89C51AC3-RLTUM 带有64K系统内可编程FLash存储器VQFP-44封装 Flash (Kbytes) 64 ISP UART Self Program Memor API EEPROM (Kbytes) 2 RAM (Bytes) 2304 F.max (MHz) 60 Vcc (V) 3-5.5 I/O Pins 32 UART 1 16-bit Timers 3 Watchdog Yes SPI Yes ADCYes Packages LQFP 64 LQFP 44 PLCC 52 PLCC 44 Pb-Free Packages LQFP 64 LQFP 44 PLCC 52 PLCC 44 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.
