ATMEGA644V

The ATMEGA644V is designed as one kind of low-power CMOS 8-bit microcontroller device that achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. And this device based on the AVR enhanced RISC architecture. Also it is manufactured using Atmel's high-density nonvolatile memory technology.

Features of the ATMEGA644V are:(1)135 Powerful Instructions Most Single Clock Cycle Execution; (2)32 x 8 General Purpose Working Registers; (3)Fully Static Operation; (4)Up to 16 MIPS Throughput at 16 MHz; (5)On-Chip 2-cycle Multiplier; (6)Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode; (7)Four 16-bit Timer/Counter with Separate Prescaler, Compare- and Capture Mode; (8)Real Time Counter with Separate Oscillator; (9)Programmable Serial USART; (10)Master/Slave SPI Serial Interface; (11)Universal Serial Interface with Start Condition Detector; (12)Programmable Watchdog Timer with Separate On-chip Oscillator; (13)On-chip Analog Comparator; (14)Interrupt and Wake-up on Pin Change.etc. If you want to know more information about the ATMEGA644V, please download the datasheet in www.seekic.com or www.chinaicmart.com .
