Overview
Description
ATmega324PV-10MUR is an 8‑bit AVR microcontroller from Microchip/Atmel’s MegaAVR family. It uses the AVR RISC core, with on‑chip flash, RAM and EEPROM, and supports in‑system programming via SPI.
Key points:
- Memory: 32 KB flash, 2 KB SRAM, 1 KB EEPROM
- Clock/grade: 10 MHz speed grade (-10)
- Peripherals: 3 timers (Timer0/Timer2 8‑bit, Timer1 16‑bit), 10‑bit ADC (several channels), USART, SPI, and TWI (I2C)
- Other: analog comparator, watchdog timer, brown‑out detector, multiple sleep modes for low power
- I/O: multiple GPIO pins (packaged‑dependent)
- Package: MU (commonly 28‑pin)
- Development: supported by standard AVR toolchain (AVR-GCC, avrdude) and compatible bootloaders
- Applications: general microcontroller tasks, sensors, small robotics, embedded control
This makes the ATmega324PV‑10MUR a compact, versatile choice for cost‑sensitive embedded projects requiring modest I/O and ADC.
