The ATMEGA644P-20MUR is an 8-bit microcontroller from Microchip Technology, part of the AVR ATmega series. It is based on the AVR enhanced RISC architecture, executing most instructions in a single clock cycle for throughput up to 20 MIPS at 20MHz. The device includes 64KB of in-system self-programmable flash memory, 2KB EEPROM, and 4KB internal SRAM.
Peripherals include two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and a real-time counter. Connectivity options include I2C, SPI, and two programmable USARTs. The microcontroller also features brown-out detection, power-on reset, and a watchdog timer.
The device is supplied in a 44-VQFN exposed pad package and supports surface mount mounting. It operates at 5V and is rated for industrial temperature ranges. The ATMEGA644P-20MUR is suitable for embedded control applications requiring low power and high performance.
The ATMEGA644P-20MUR uses an 8-bit AVR RISC core.
The maximum speed is 20MHz, providing up to 20 MIPS throughput.
It supports I2C, SPI, and UART/USART interfaces.
It is supplied in a 44-VQFN exposed pad package (44-VFQFN).
The RoHS status is listed as non-compliant.
