概要

Description

ATmega165P-16AUR is an 8‑bit AVR microcontroller from Atmel/Microchip, part of the ATmega165 family. It uses the AVR RISC core and typically runs up to 16 MHz. On‑chip memory includes flash program memory (16 KB), plus EEPROM and RAM (sizes per datasheet). Peripherals commonly include multiple I/O lines, two 8‑bit timers and one 16‑bit timer, a 8‑channel 10‑bit ADC with PWM outputs, and serial interfaces such as USART, SPI, and I²C/TWI, plus watchdog and analog comparators. It supports in‑system programming via SPI and is compatible with the standard AVR toolchain (AVR-GCC, Atmel Studio, avrdude).
The -16AUR suffix encodes the device variant: 16 MHz speed, and AU/UR packaging options (e.g., TQFP/leadframe options and temperature range as defined in the datasheet). It’s suitable for embedded control, sensing, and small automation tasks.
For exact specs (pinout, voltage range, RAM/EEPROM sizes, and temperature range), consult the official ATmega165P datasheet and product page.
