ATMEGA329V-8AU

ATmega329V-8AU is an 8‑bit AVR microcontroller from Atmel (Microchip) in the megaAVR family. It uses the AVR RISC core, delivering compact, predictable instruction timing and efficient code execution. The “8” in the name typically indicates 8 KB of flash program memory; the “AU” suffix denotes the 32‑pin TQFP package. It provides a range of on‑chip peripherals (I/O lines, timers/counters, USART/SPI/I2C, ADC, and nonvolatile storage options like EEPROM) suitable for cost‑effective embedded control, sensor interfacing, and hobby projects. It supports standard AVR development flows (C/C++, AVR-GCC, Atmel Studio or Microchip MPLAB) and in‑system programming via SPI/ISP. For exact memory sizes, peripheral counts, clock/frequency limits, package pinout, and voltage ranges, consult the official datasheet and package drawings.

Manufacturer: Atmel Corporation (now part of Microchip Technology). Atmel was a semiconductor company that designed and manufactured embedded microcontrollers (notably the AVR family), memory, and related ICs. In 2016, Atmel was acquired by Microchip Technology, a US-based multinational semiconductor company specializing in microcontrollers, analog, memory, and other embedded IC solutions.
