ATUC128D3-A2UT Description

Short technical summary and product information.

The ATUC128D3-A2UT is a 32-bit AVR microcontroller based on the AVR32UC architecture, manufactured by Microchip Technology. It integrates 128KB of Flash program memory and 16KB of SRAM, operating at a maximum clock frequency of 48MHz. The device supports a wide supply voltage range from 1.65V to 3.6V, making it suitable for low-power embedded applications.

 

Peripherals include seven DMA channels, three 16-bit timer/counters, a 7-channel 12-bit PWM, and an 8-channel 10-bit ADC. Communication interfaces cover I2C, SPI, UART/USART, and USB 2.0 full-speed. The microcontroller also features capacitive touch support for up to 25 buttons and a windowed watchdog timer.

 

The device is housed in a 64-LQFP (10x10mm) surface-mount package and operates over an industrial temperature range of -40°C to +85°C. It offers brown-out detection, reset, and internal oscillator, providing a reliable solution for system control.
