ATMEGA165P-16AUR

ATmega165P-16AUR is an 8-bit AVR microcontroller from Atmel (now Microchip), part of the MegaAVR family. It uses a RISC AVR core and runs up to 16 MHz. Typical on‑chip resources include: 16 KB flash program memory, 1 KB RAM, and 512 bytes EEPROM; 8-channel 10-bit ADC; two 8-bit timers plus one 16-bit timer; USART, SPI, and I2C (TWI); up to ~32 I/O pins (depends on package); analog comparator; watchdog timer; power-on reset and brown‑out detection. It supports in‑system programming (ISP) via SPI and is commonly programmed with AVR-GCC/Atmel Studio. The suffix 16AUR indicates a 16 MHz device in a RoHS‑compliant package (AU) with standard industrial temperature range. Typical applications include embedded controllers, sensor interfaces, motor control, and other small to mid‑range control tasks. Note: exact RAM/EEPROM sizes and features can vary by variant; consult the datasheet for your specific package/temperature range.
