The Microchip ATMEGA325-16AU is an 8-bit AVR microcontroller with 32KB flash and 2KB SRAM, running at 16MHz. It operates from 2.7V to 5.5V and is housed in a 64-TQFP package. With integrated PWM, WDT, and brown-out detection, it suits industrial control and display applications requiring many I/O lines.
- High I/O count: 54 programmable I/O pins enable complex interfaces without external expanders.
- Fast 16MHz execution: Handles real-time tasks like sensor sampling and communication protocols.
- Flexible power: 2.7V-5.5V range supports battery or regulated supplies.
- Mature AVR ecosystem: Extensive libraries and tools accelerate firmware development.
Industrial Display Panels
The 64-pin package provides enough I/O to drive alphanumeric LCDs and read keypads in HMI systems.
Data Acquisition Units
With 2KB RAM and multiple ADC channels, it can sample analog sensors for factory monitoring.
