The ATMEGA645A-AU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 64KB of in-system self-programmable Flash memory, 4KB SRAM, and 2KB EEPROM, providing ample memory for complex embedded applications.
Operating at up to 16MHz, the device delivers up to 16 MIPS throughput. It includes 54 programmable I/O lines, an 8-channel 10-bit ADC, two 8-bit and one 16-bit timer/counters, four PWM channels, and connectivity options including SPI, UART/USART, and USI. The microcontroller supports multiple sleep modes for power-sensitive designs.
The ATMEGA645A-AU is housed in a 64-TQFP (14x14mm) surface mount package and operates over a temperature range of -40°C to 85°C. It supports a wide supply voltage range of 1.8V to 5.5V, making it suitable for both low-power and high-speed applications. The device is RoHS3 compliant and REACH unaffected.
Typical applications include consumer electronics, industrial automation, medical devices, and automotive systems. Microchip's MPLAB X IDE and development tools support rapid prototyping and deployment.
