The ATMEGA328PB-ABTVAO from Microchip is a high-performance 8-bit AVR MCU with 32KB flash and 2KB SRAM. It operates from 1.8V to 5.5V at up to 20MHz, featuring BOD, POR, PWM, and WDT. Housed in a 32-TQFP package, it supports industrial temperature ranges from -40°C to 105°C, making it a robust choice for embedded control.
- Wide voltage range (1.8V-5.5V) enables flexible power design, from single-cell batteries to regulated 5V rails.
- 20MHz AVR core delivers fast instruction execution, reducing response time in real-time control loops.
- 32KB flash provides ample code space for complex firmware, avoiding external memory.
- 105°C operating temperature ensures reliability in harsh thermal environments.
Industrial Sensor Nodes
With 1.8V operation and multiple PWM channels, it efficiently reads analog sensors and drives actuators in low-power factory automation.
Battery-Powered IoT Devices
The 1.8V minimum supply and WDT enable long sleep cycles, making it ideal for wireless environmental monitors.
Motor Control for Drones
20MHz speed and 6 PWM channels allow precise ESC control for small quadcopters.
Automotive Aftermarket Modules
105°C rating and BOD ensure reliable operation in engine bay or cabin lighting controllers.
Portable Medical Instruments
Low voltage and POR protect data integrity in handheld glucose meters or pulse oximeters.
Smart Agriculture Probes
2KB SRAM buffers soil moisture readings while the AVR core processes calibration algorithms at 20MHz.
