The ATMEGA324PA is an 8-bit AVR MCU from Microchip with 32KB flash and 2KB SRAM. It operates from 1.8V to 5.5V at up to 20MHz, featuring brown-out detection, POR, PWM, and WDT. The 44-VQFN package with exposed pad aids thermal dissipation in compact designs.
- Ultra-low voltage operation (1.8V) – enables single-cell battery designs without boost converters.
- High-speed 20MHz AVR core – executes most instructions in one clock cycle for real-time tasks.
- Integrated brown-out and POR – prevents corrupt execution during power transients.
- Exposed pad VQFN – improves thermal performance in sealed enclosures.
Industrial Sensor Nodes
Operates from 1.8V enabling direct battery-powered sensing with low-power sleep modes.
Portable Medical Devices
Wide voltage range supports coin-cell and Li-ion with brown-out detection for data integrity.
Motor Control Hubs
PWM channels and WDT provide reliable commutation and fault recovery in 5V industrial drives.
Smart Home Controllers
20MHz throughput handles Zigbee/Sub-GHz protocol stacks with 32KB flash for application code.
Automotive Body Electronics
-40°C to 85°C and POR ensure robust operation in cabin control modules.
Data Loggers
2KB SRAM buffers sensor samples; low-power modes extend logging duration.
