ATMEGA1281V-8MU Description

Short technical summary and product information.

The ATMEGA1281V-8MU is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance AVR core running at 8 MHz, providing 128KB of Flash program memory, 8KB of SRAM, and 4KB of EEPROM for data storage. The device is equipped with a rich set of peripherals including brown-out detection, power-on reset, pulse-width modulation (PWM), and a watchdog timer.

 

This microcontroller offers extensive connectivity options with EBI/EMI, I²C, SPI, and UART/USART interfaces, along with 54 general-purpose I/O pins. It includes an 8-channel 10-bit analog-to-digital converter for analog signal processing. The operating voltage range of 1.8V to 5.5V allows for flexible power supply designs, and the industrial temperature range of -40°C to 85°C makes it suitable for demanding environments.

 

The device is housed in a 64-VFQFN exposed pad package (64-QFN 9x9mm), enabling surface-mount assembly for compact designs. The internal oscillator eliminates the need for external clock components, reducing board space and cost. This microcontroller is ideal for embedded control applications requiring moderate processing power and a wide range of I/O and communication interfaces.
