ATUC128L4U-AUT Description

Short technical summary and product information.

The ATUC128L4U-AUT is a 32-bit AVR microcontroller from Microchip Technology based on the high-performance, low-power AVR UC3 RISC architecture. It operates at speeds up to 50MHz delivering up to 64 DMIPS from flash with one wait state. The device integrates 128KB of flash program memory, 32KB of SRAM, and includes a Memory Protection Unit (MPU) with Secure Access Unit for peripheral protection.

 

Peripherals include brown-out detect/reset, DMA, POR, PWM, and watchdog timer. Connectivity options cover I²C, SPI, UART/USART, and USB interfaces. An internal oscillator simplifies clock generation. The microcontroller also features an 8-channel 12-bit A/D converter.

 

The device is housed in a 48-TQFP surface mount package (7x7mm) and operates over an ambient temperature range of -40°C to 85°C. Supply voltage range is 1.62V to 3.6V. It is suitable for embedded control applications requiring moderate processing power, USB connectivity, and low power consumption.
