Description
The ATMEGA644P-20AUR is a 8-bit low-power high-performance CMOS Microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega644P achieves throughputs approaching 1 MIPS per MHz allowing the system designed to optimize power consumption versus processing speed. The ATmega644P provides the following features 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 timer/counters with compare modes, 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 standard 1149.1 compliant JTAG test interface, also used for accessing the on-chip debug system and programming and six software selectable power saving modes.
- Advanced RISC architecture, fully static operation and up to 20MIPS throughput at 20MHz
- High endurance non-volatile memory segments
- Write/erase cycles of 10000 flash/100000 EEPROM
- Boundary-scan capabilities according to the JTAG standard
- Extensive on-chip debug support
- Programming of flash, EEPROM, fuses and lock bits through the JTAG interface
- Real time counter with separate oscillator
- Two 8-bit timer/counters with separate prescalers and compare modes
- Byte-oriented two-wire serial interface
- Two programmable serial USART
- Serial peripheral interface (SPI)
- Programmable watchdog timer with separate on-chip oscillator
- Power-on reset and programmable brown-out detection
- Internal calibrated RC oscillator
- External and internal interrupt sources
