概要
Description
Key peripherals include:
- 23 programmable I/O pins
- 6-channel 10-bit ADC
- 3 timers/counters (including PWM)
- USART, SPI, and I²C for serial communication
The "PA" suffix indicates low-power optimization, while "AU" denotes a TQFP-32 package. It supports 1.8V–5.5V operation, making it suitable for battery-powered and embedded applications.
Common uses include industrial control, consumer electronics, and DIY projects. It’s code-compatible with other ATmega48/88/168 models, easing migration.
For development, tools like Atmel Studio (now Microchip MPLAB X) and AVR-GCC are recommended.
Equivalent
- ATMEGA48PA-MU (QFN package)
- ATMEGA48A-AU (similar specs, older revision)
- ATMEGA48P-AU (slightly lower performance)
- ATMEGA88PA-AU (higher flash, pin-compatible)
- ATMEGA168PA-AU (double flash/RAM, pin-compatible)
All are 8-bit AVR microcontrollers with similar features. Verify pinouts and specs for exact compatibility.
