The Microchip ATMEGA6450P-AU is an 8-bit AVR microcontroller with 64KB flash and 4KB SRAM. Supporting 1.8V-5.5V operation at 20MHz, it comes in a 100-TQFP package with PWM, WDT, and brown-out detection, suitable for complex embedded systems requiring many I/O pins.
- Large Memory: 64KB flash and 4KB SRAM support complex applications and data buffering.
- Ultra-Low Voltage: 1.8V operation enables battery-powered designs with minimal power consumption.
- High Pin Count: 100-pin TQFP provides extensive I/O for peripheral interfacing.
- Robust Protection: Includes POR, brown-out detect, and WDT for reliable system operation.
Large Display Systems
The 100-pin package provides ample I/O for driving segment LCDs or LED matrices, while 64KB flash stores complex display patterns and animations.
Data Logging Equipment
With 4KB SRAM and low-power modes, it can buffer sensor data and write to external memory, operating from 1.8V for energy-efficient logging.
Portable Instrumentation
The 1.8V minimum supply enables single-cell battery operation, and the 20MHz core handles real-time calculations for handheld multimeters or thermometers.
Building Automation
Multiple PWM channels and WDT support HVAC damper control and lighting systems, with the wide voltage range accommodating 3.3V or 5V logic.
Metering Solutions
Ideal for smart meters, the 64KB flash stores calibration data and communication protocols, while the AVR core ensures accurate pulse counting.
Robotics Controllers
The 100-TQFP offers enough GPIOs for motor drivers and encoders, and the 20MHz speed enables fast PID loop calculations.
