概述

Description

ATmega324PV-10MU is an 8‑bit AVR microcontroller from Atmel (Microchip) in a 40‑pin MU package. It uses the AVR RISC core with most instructions executing in one clock cycle.
Key features
- Memory: ~32 KB flash, 2 KB SRAM, 1 KB EEPROM
- Peripherals: 8/16/32‑bit timers, PWM outputs, 8‑channel 10‑bit ADC, USART, SPI, I2C/TWI, analog comparator, watchdog timer, brown‑out detector
- I/O: multiple general‑purpose I/O lines distributed across the 40 pins
- Clock/speed: up to 10 MHz (speed grade -10), operating voltage typically 1.8–5.5 V (depending on clock)
- Power/low‑power: sleep modes and other power features for energy efficiency
- Development: supported by standard AVR toolchain (AVR-GCC, AVRDUDE), programmed via In‑System Programming (ISP)
Use cases
- Small to mid‑size embedded controllers and hobbyist projects
- Sensor interfacing, motor control, simple automation, and general purpose I/O tasks
Note: packaging code MU denotes the 40‑pin surface‑mount package variant.

Features

ATmega324PV-10MU features (concise):
- 8-bit AVR RISC CPU, up to 10 MHz operation
- Memory: 32 KB Flash program memory with In-System Programming; 1 KB EEPROM; 2 KB SRAM
- I/O and peripherals: 24 general-purpose I/O lines (Ports A–C)
- Timers: Timer0 (8-bit), Timer1 (16-bit), Timer2 (8-bit) with PWM
- ADC: 8-channel, 10-bit ADC
- Analog comparator
- Communication interfaces: USART, SPI, I2C (TWI)
- Rich set of interrupts and wake-up sources
- Power features: Brown-out detector, Power-On Reset, multiple sleep modes
- Programming/debug: In-system programming via SPI (no external programmer required for flash)
- Package: 28-pin MU (SOIC/SOIC-like) compact package
Note: Max clock 10 MHz; operating voltage generally 1.8–5.5 V (check datasheet for exact conditions).

Package

The ATMEGA324PV-10MU comes in a 44-pin μQFP (μQFP) package.

Pinout

- Pin count: 40 pins (MU package, SOIC-40).
- Function: An 8‑bit AVR microcontroller (ATmega324P family) with on‑chip memory, multiple I/O pins, ADCs, timers, and serial interfaces (USART, SPI, I2C/TWI) for embedded control applications.

Manufacturer

Equivalent

The ATmega324PV-10MU is the same silicon as other variants in the ATmega324P family. Equivalents are other package/speed variants of the same device, e.g.:
- ATmega324PV-10PU (same chip, different package)
- ATmega324PV-12MU, ATmega324PV-20MU (different clock speeds)
