The ATMEGA325A-MUR from Microchip is an 8-bit AVR microcontroller in a compact 64-VFQFN package with an exposed pad for enhanced thermal management. It operates at 20MHz with 32KB flash and 2KB SRAM, supporting a supply range of 1.8V to 5.5V. On-chip features include brown-out detection, power-on reset, PWM, and a watchdog timer, making it a versatile choice for space-constrained embedded designs.
- Compact VFQFN package with exposed pad improves heat dissipation for high-current I/O.
- Wide operating voltage (1.8V-5.5V) enables flexible power architectures.
- 20MHz performance with 32KB flash for substantial application code.
- Robust reset and brown-out circuitry enhances system reliability.
- Industrial temperature range supports outdoor and automotive cabin applications.
Compact IoT Endpoints
The VFQFN package's small footprint and exposed pad allow dense PCB layouts for smart home sensors, while the 20MHz AVR core handles MQTT protocol stacks efficiently.
Motor Control for Drones
PWM outputs and the 5.5V supply capability drive ESC signals directly, while the 2KB SRAM buffers telemetry data for flight controller communication.
Portable Instrumentation
Low-power sleep modes and fast wake-up from the watchdog timer make it ideal for handheld multimeters or data loggers, with the exposed pad improving thermal performance under continuous load.
LED Display Drivers
Multiple PWM channels can drive RGB LED matrices in signage, with the 32KB flash storing character maps and animation sequences.
Security Keypads
The brown-out detector ensures secure startup for access control panels, and the 64-pin package provides enough GPIOs for matrix scanning and tamper detection.
Robotics Controllers
Combine sensor inputs and servo PWM signals in a single 5V system, using the 2KB SRAM for kinematic calculations at 20MHz.
