概要

Description

ATmega324PA-MUR is an 8‑bit AVR microcontroller from Atmel/Microchip. It offers 32 KB flash, 2 KB RAM, 1 KB EEPROM, and about 32 I/O lines, plus a rich peripheral set: two 8‑bit timers, one 16‑bit timer with PWM, a 10‑bit ADC (8 channels), USART, SPI, I2C (TWI), a watchdog timer, and power/low‑power features with sleep modes and brown‑out/POR protection. It operates from 1.8 to 5.5 V and up to 20 MHz (voltage/clock dependent). The -MUR suffix identifies a specific package/temperature variant; check the datasheet for exact pinout and package details. Typical uses include general control, sensor interfacing, data acquisition, and small embedded systems for hobby or industrial projects. Development is via AVR-GCC or Microchip Studio (formerly Atmel Studio), with programming over SPI/UART. For exact specs, pinout, and packaging, refer to the ATmega324PA datasheet and packaging guide.
