ATMEGA324PA-MU

The ATMEGA324PA-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 32KB of in-system self-programmable Flash memory, 2KB of internal SRAM, and 1KB of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM). The device supports a maximum clock frequency of 20 MHz, delivering up to 20 MIPS throughput.

This microcontroller includes a rich set of peripherals: two 8-bit and one 16-bit timer/counters, 6 PWM channels, an 8-channel 10-bit ADC, and connectivity interfaces including I²C, SPI, and UART/USART. It also features brown-out detection, power-on reset, and a watchdog timer. The operating voltage range is 1.8V to 5.5V, with speed grades varying by voltage: 0-4 MHz at 1.8V-5.5V, 0-10 MHz at 2.7V-5.5V, and 0-20 MHz at 4.5V-5.5V.

The device is designed for surface mount assembly in a 44-VFQFN exposed pad package (supplier package 44-VQFN 7x7mm). It operates over an industrial temperature range of -40°C to +85°C. The ATmega324PA-MU is suitable for a wide range of embedded control applications requiring moderate memory and I/O capabilities.
