Overview

Description

ATmega329V-8AU is an 8-bit AVR microcontroller from Atmel (now Microchip) in a 32-pin TQFP package (AU). It uses the AVR RISC core for compact, low-power embedded control.
Key points:
- Memory: nonvolatile flash for code, EEPROM, and SRAM for runtime data.
- Peripherals: multiple I/O pins, timers with PWM, ADC, and serial interfaces (USART/UART, SPI, I2C/TWI). Includes watchdog, brown-out detector, and various clock options with sleep modes for low power.
- Voltage/speed: designed for wide supply voltages (typical 1.8–5.5 V) with clock frequencies depending on voltage.
- Development: supported by AVR-GCC, Atmel Studio, and other toolchains; programmable via SPI or bootloader.
- Applications: suitable for small embedded controllers, sensor interfacing, hobby electronics, and simple automation.
Note: exact flash/EEPROM/SRAM sizes and peripheral counts vary by variant; consult the datasheet for the -8AU specifics.

Equivalent

There isn’t an exact drop‑in equivalent for ATMEGA329V-8AU; it’s a specific 8‑KB AVR in a particular package. Closest substitutes by memory within the AVR line are: ATmega8A (8 KB), ATmega48/88/168 (4/8/16 KB), and ATmega328P (32 KB). For pin‑out compatibility, consult Microchip/Atmel cross‑references; migration often requires wiring changes and code adjustments.
