ATMEGA644PA-AU
Available in stock
The ATMEGA644PA-AU from Microchip Technology is a high-performance, low-power 8-bit AVR microcontroller housed in a TQFP-44 package. Part of the AVR picoPower® family, it combines substantial Flash program memory, SRAM, EEPROM, digital I/O, timers/counters, PWM outputs, ADC, SPI, USART, TWI (I²C), analog comparator, watchdog timer, and interrupt capabilities into a single integrated device. Its rich peripheral set and efficient AVR RISC architecture make it an excellent choice for demanding embedded applications.
The Microchip ATMEGA644PA-AU is widely used in industrial automation, IoT devices, robotics, instrumentation, consumer electronics, smart appliances, data acquisition systems, and embedded control applications. With increased memory capacity compared to many standard AVR microcontrollers, it is well suited for applications requiring larger firmware, multiple communication interfaces, and complex real-time processing. The compact TQFP-44 package enables space-efficient PCB layouts while providing sufficient I/O for feature-rich electronic designs.
Engineers searching for an ATMEGA644PA-AU, ATmega644PA TQFP-44, AVR picoPower microcontroller, 8-bit Microchip MCU, or embedded controller IC frequently choose this device for embedded firmware development, OEM product design, prototype validation, industrial equipment, and commercial manufacturing. The ATMEGA644PA-AU remains a reliable and scalable solution for advanced embedded system development.
Bharat Labs supports sourcing and supply of original Microchip Technology ATMEGA644PA-AU microcontrollers for prototyping, R&D, embedded development, electronics manufacturing, repair, and production requirements.
