Visão Geral
Description
Key upgrades over the ATmega328P include:
- Dual USART for enhanced serial communication.
- Independent PLL clock for USB and other peripherals.
- More timers (four 16-bit) and additional PWM channels.
- Better noise immunity and lower power consumption.
It operates at 1.8V–5.5V, making it suitable for battery-powered and industrial applications. The -ANR suffix indicates a TQFP-32 package, ideal for compact designs.
Common uses include Arduino-compatible boards, embedded systems, and IoT devices. Its backward compatibility with the ATmega328P allows easy migration for existing projects.
For detailed specs, refer to the Microchip datasheet.
Equivalent
- ATMEGA328P-AU (similar but lacks some peripherals).
- ATMEGA328PB-AU (same features, different package).
- ATMEGA168PB (lower flash but compatible).
- ATMEGA328 (earlier version, fewer features).
- PIC18F45K22 (Microchip alternative, requires code adaptation).
- STM32F030F4P6 (ARM-based, more powerful but different architecture).
For direct replacements, ATMEGA328PB-AU is the closest match.
Features
- Core: 8-bit AVR, up to 20 MHz clock speed.
- Memory: 32KB Flash, 2KB SRAM, 1KB EEPROM.
- Peripherals:
- More Timers: Four 8-bit & two 16-bit timers (vs. ATmega328P’s three).
- Extra USART: Two USARTs (vs. one in 328P).
- Enhanced SPI/I²C: Two SPI & two I²C interfaces.
- ADC: 10-bit, 8-channel ADC.
- GPIO: 23 programmable I/O pins.
- Power: 1.8V–5.5V operating voltage.
- Package: 32-pin QFN.
- Debugging: DebugWIRE support.
Ideal for embedded systems needing extra serial comms or timers.
Pinout
- GPIO: 23 programmable I/O pins.
- Communication:
- USART (2x), SPI, I²C (TWI).
- Timers: Three 8-bit and one 16-bit timer/counter.
- ADC: 8-channel 10-bit ADC.
- PWM: 6 PWM outputs.
- Memory:
- 32KB Flash, 2KB SRAM, 1KB EEPROM.
- Clock: Up to 20MHz (external) or 8MHz (internal).
It retains Arduino Uno (ATMEGA328P) compatibility while adding extra peripherals like a second USART.
Manufacturer
Microchip, founded in 1989 and headquartered in Chandler, Arizona, is known for its PIC and AVR microcontrollers, widely used in embedded systems. The company acquired Atmel (the original developer of AVR) in 2016, expanding its portfolio.
The ATmega328PB-ANR is an enhanced version of the popular ATmega328P, featuring additional peripherals like extra timers and USARTs. It is commonly used in industrial, automotive, and consumer electronics.
Microchip is recognized for its reliable, low-power microcontrollers and strong support for developers.
Application
- Consumer Electronics (smart home devices, toys)
- Industrial Automation (sensors, control systems)
- Automotive (basic control modules, diagnostics)
- IoT & Wearables (sensor nodes, wireless devices)
- DIY & Hobbyist Projects (Arduino-compatible boards, robotics)
- Medical Devices (simple monitoring systems)
Its enhanced peripherals (extra UART, timers) make it ideal for communication-heavy and real-time control applications.
