ATMEGA165P-16MU Description

Short technical summary and product information.

The ATMEGA165P-16MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It operates at up to 16 MHz and features 16 KB of in-system self-programmable Flash memory, 1 KB of SRAM, and 512 bytes of EEPROM. The device includes an 8-channel 10-bit ADC, multiple serial interfaces (SPI, UART/USART, USI), and 54 general-purpose I/O lines. Peripherals include brown-out detection, power-on reset, PWM channels, and a watchdog timer.

 

The microcontroller supports a supply voltage range of 2.7V to 5.5V and operates over an industrial temperature range of -40°C to 85°C. It is available in a 64-pin QFN (9x9 mm) surface-mount package with an exposed pad for improved thermal performance. The internal oscillator eliminates the need for external clock components.

 

Typical applications include industrial control, consumer electronics, automotive systems, medical devices, and smart home automation. The device is supported by Microchip's MPLAB X IDE and XC8 compiler, along with various development boards and libraries.
