The ATMEGA128A-AN is a high-performance 8-bit AVR microcontroller from Microchip in a 64-TQFP package. It runs at 16MHz with 128KB flash and 4KB SRAM, operating from 2.7V to 5.5V. Integrated features include PWM, WDT, POR, and Brown-out Detect/Reset, with an extended -40°C to 105°C range for demanding environments.
- Extended temperature range: -40°C to 105°C for harsh industrial/automotive use.
- Large 128KB flash: Supports complex firmware and data logging.
- High-speed 16MHz AVR core: Fast execution for real-time control loops.
- 64-TQFP package: Good pin count for peripheral-rich designs.
Automotive ECU Subsystems
The 105°C rating and 16MHz speed handle engine sensor fusion and CAN bridge applications.
Industrial PLC I/O Modules
128KB flash stores complex ladder logic, while 4KB RAM buffers real-time fieldbus data.
Medical Device Controllers
High reliability with Brown-out Reset ensures safe operation in infusion pumps or ventilators.
Smart Grid Meters
Low 2.7V operation and robust peripherals support multi-phase energy measurement.
Robotics Motor Controllers
PWM outputs and 16MHz speed enable precise servo loops in 64-TQFP compact boards.
Building Automation Gateways
Large memory and wide temperature range suit HVAC zone controllers with Ethernet bridges.
