The ATMEGA644P-20MQR is an 8-bit AVR microcontroller from Microchip Technology based on the AVR enhanced RISC architecture. It features 64KB of Flash program memory, 4KB of SRAM, and 2KB of EEPROM, providing ample storage for embedded control applications. The device operates at a maximum speed of 20 MHz, delivering up to 20 MIPS throughput.
With 32 general-purpose I/O lines, the microcontroller supports connectivity via I²C, SPI, and UART/USART interfaces. It includes an 8-channel 10-bit analog-to-digital converter (ADC) and six PWM channels, along with peripherals such as brown-out detection, power-on reset, and watchdog timer. The operating voltage range is 2.7V to 5.5V, and the temperature range is -40°C to 105°C.
The device is offered in a 44-VFQFN exposed pad package (44-VQFN, 7x7 mm) for surface mount assembly. This combination of features makes it suitable for a wide range of embedded systems requiring low power consumption and high performance.
