ATMEGA2561-16AUR Description

Short technical summary and product information.

The ATMEGA2561-16AUR is an 8-bit AVR microcontroller from Microchip Technology featuring 256KB of Flash program memory, 8KB of SRAM, and 4KB of EEPROM. It operates at a clock frequency of 16 MHz and supports a supply voltage range of 4.5V to 5.5V. The device includes 54 general-purpose I/O lines and a rich set of peripherals including Brown-out Detect/Reset, Power-On Reset, PWM, and Watchdog Timer. Connectivity options include EBI/EMI, I²C, SPI, and UART/USART interfaces. An 8-channel 10-bit ADC is integrated for analog signal conversion. The microcontroller is housed in a 64-TQFP surface-mount package with a 14x14 mm body. It is suitable for a wide range of embedded applications requiring moderate processing power and extensive I/O capabilities. The internal oscillator eliminates the need for external clock components in many designs. The operating temperature range is -40°C to 85°C, making it suitable for industrial environments.
