Description
The ATMEGA328PB-AN is an advanced, low-power 8-bit AVR RISC-based microcontroller featuring 32KB of flash memory. Building upon the performance of the ATmega328 series, this “PB” variant includes enhanced peripherals like a dedicated Peripheral Touch Controller (PTC) for capacitive touch interfaces, dual USARTs, and expanded PWM channels. With its ability to achieve throughputs approaching 1 MIPS per MHz and an extended industrial operating temperature range up to 105°C, it is an exceptionally versatile choice for high-reliability embedded control and human-machine interface (HMI) applications.
Key Features
- Advanced AVR® Architecture: 131 powerful instructions with single-cycle execution, balancing speed and energy efficiency.
- Peripheral Touch Controller (PTC): Dedicated hardware for supporting capacitive touch buttons, sliders, and wheels.
- Enhanced Communication: Includes dual programmable serial USARTs, plus SPI and I2C interfaces.
- Advanced PWM: Features 10 PWM channels for sophisticated motor control and signal modulation.
- Wide Operating Range: Operates from 1.8V to 5.5V and features an extended industrial temperature range (-40°C to 105°C).
- Low Power Design: Six distinct sleep modes and programmable brown-out detection for battery-critical projects.
Applications
- Human-Machine Interfaces: Ideal for devices utilizing capacitive touch control panels.
- Industrial Automation: Reliable operation in demanding environments requiring higher temperature tolerance.
- Consumer Electronics: Highly efficient controller for smart devices and integrated household appliances.
- Advanced Prototyping: A powerful successor to the standard ATmega328, offering expanded peripheral capabilities.
