The ATMEGA644P-20AQR is an 8-bit AVR microcontroller from Microchip Technology's ATmega family. It features 64KB of in-system self-programmable Flash memory, 4KB of internal SRAM, and 2KB of EEPROM. The device operates at a maximum clock speed of 20MHz, delivering up to 20 MIPS throughput.
This microcontroller includes a rich set of peripherals: two 8-bit timer/counters, one 16-bit timer/counter, six PWM channels, an 8-channel 10-bit ADC, and serial connectivity via I²C, SPI, and two USART interfaces. It also integrates a brown-out detect/reset, power-on reset, and a watchdog timer.
The device is housed in a 44-pin TQFP package with a 10x10mm body and is rated for surface mount assembly. It supports an operating temperature range of -40°C to 105°C and a supply voltage from 2.7V to 5.5V, making it suitable for industrial and extended-temperature applications.
The supply voltage range is 2.7V to 5.5V.
It is available in a 44-TQFP package (10x10mm) for surface mount assembly.
The operating temperature range is -40°C to 105°C.
It is listed as ROHS3 Compliant, though this is unverified.
It has 64KB of Flash program memory.
It supports I²C, SPI, and UART/USART interfaces.
There are 32 I/O pins.
