ATMEGA324PA in ATmega Family
The ATMEGA324PA is a high-performance, low-power 8-bit microcontroller based on the Microchip (formerly Atmel) AVR RISC architecture. Specifically designed for applications requiring high reliability and power efficiency, it integrates 32KB of self-programming flash memory, 2KB SRAM, and 1KB EEPROM. Operating at up to 20MHz, it provides an optimal balance between processing throughput and energy consumption, making it a staple in industrial and consumer embedded systems where standard peripherals and code efficiency are critical requirements.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Package | Stock |
|---|---|---|
| ATMEGA324PA-MUR (Microchip Technology) | VFQFN-44 | 8,765 |
| ATMEGA324PA-AU (Microchip Technology) | TQFP-44 | 5,379 |
Variants within the ATMEGA324PA sub-family are distinguished primarily by their physical packaging and temperature grading. Options include the 44-lead TQFP for surface mount assembly, the 40-pin PDIP for through-hole prototyping, and the 44-pad VQFN for space-constrained designs. Some variants are qualified for automotive applications (A-suffix) or extended industrial temperature ranges, though the internal silicon logic and memory density remain consistent across the sub-family.
