개요
Description
The ATmega328PB-MNR is a microcontroller from Microchip’s AVR family, an enhanced version of the popular ATmega328P. It features:
- 8-bit AVR RISC architecture (up to 20 MHz).
- 32KB Flash, 2KB SRAM, and 1KB EEPROM.
- Additional peripherals vs. ATmega328P (e.g., extra UART, SPI, and timers).
- Low-power operation with multiple sleep modes.
- 28-pin MLF (QFN) package (surface-mount).
Ideal for embedded applications like IoT, automation, and DIY projects (e.g., Arduino-compatible designs). The -MNR suffix denotes tape-and-reel packaging for mass production.
Key advantages: Cost-effective, versatile, and backward-compatible with ATmega328P designs.
