ATMEL ATMEGA644-20MU 微控制器, 8位, 低功率高性能, ATmega, 20 MHz, 64 KB, 4 KB, 44 引脚, VQFN
The is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 64kB ISP flash memory with read-while-write capabilities, 2kB EEPROM, 4kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, real time counter, three flexible timers/counters with compare modes and PWM, 2 USARTs, byte oriented 2-wire serial interface, 8-channel/10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, JTAG IEEE 1149.1 compliant test interface for on-chip debugging and six software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock-cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.
