The ATMEGA644PV-10PU is a low-power 8-bit CMOS AVR RISC-based Microcontroller. By executing powerful instructions in a single clock cycle, the ATmega644P achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The ATmega644P provides 64kB of in-system programmable flash with read-while-write capabilities, 2kB EEPROM, 4kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, Real Time Counter (RTC), three flexible timers/counters with compare modes and PWM, 2 USARTs, a byte oriented 2-wire Serial Interface, a 8- channel, 10-bit ADC with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test interface.

• Advanced RISC architecture
• Power-on reset and programmable brown-out detection
• Internal calibrated RC oscillator
• External and internal interrupt sources
• Six sleep modes - idle, ADC noise reduction, power-save, power-down, standby and extended standby
• 131 Powerful instructions-most single clock cycle execution
• 32 x 8 General purpose working registers
• Fully static operation
• Up to 20MIPS throughput at 20MHz
• On-chip 2-cycle multiplier

• JTAG (IEEE std. 1149.1 compliant) interface
• Programmable watchdog timer with separate on-chip oscillator
• On-chip analog comparator
• Interrupt and wake-up on pin change
• Two 8-bit timers/counters with separate prescalers and compare modes
• One 16-bit timer/counter with separate prescaler, compare mode and capture mode
• Real-time counter with separate oscillator
• Six PWM channels
• Two programmable serial USART
• Master/Slave SPI serial interface
