The Microchip Technology ATMEGA644P-20AQ is an 8-bit AVR microcontroller based on the enhanced RISC architecture. It operates at a maximum speed of 20MHz, delivering up to 20 MIPS throughput. The device integrates 64KB of in-system self-programmable Flash memory, 4KB of SRAM, and 2KB of EEPROM with high endurance (10,000 write/erase cycles for Flash and 100,000 for EEPROM). Data retention is rated at 20 years at 85°C and 100 years at 25°C.
Peripherals include two 8-bit and one 16-bit timer/counters, six PWM channels, an 8-channel 10-bit ADC, and a real-time counter. Connectivity options include I2C, SPI, and two USART interfaces. The device also features brown-out detection, power-on reset, and a watchdog timer. It operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 105°C.
The microcontroller is housed in a 44-pin TQFP package with a 10x10mm body and is designed for surface-mount assembly. It is suitable for a wide range of embedded applications requiring low power consumption and high performance.
The operating voltage range is 2.7V to 5.5V.
It comes in a 44-pin TQFP package (44-TQFP) with a 10x10mm body, surface mount.
The operating temperature range is -40°C to 105°C.
RoHS compliance is indicated as RoHS3 compliant, but this is unverified and should be confirmed with the manufacturer.
The Flash memory is 64KB with a minimum endurance of 10,000 write/erase cycles.
It supports I2C, SPI, and UART/USART interfaces.
Typical active mode current is 0.4 mA at 1MHz, 1.8V, and 25°C.
