ATSAM4LS4CA-AUR Description

Short technical summary and product information.

The ATSAM4LS4CA-AUR is a 32-bit ARM Cortex-M4 microcontroller from Atmel's SAM4L series, designed for ultra-low power applications. It operates at up to 48MHz and features 256KB of Flash memory and 32KB of RAM. The device includes a wide range of peripherals such as I²C, SPI, UART/USART, USB, and IrDA interfaces, along with analog converters (15-channel 12-bit ADC, 1-channel 10-bit DAC). It supports brown-out detect, DMA, PWM, and watchdog timer. The microcontroller is available in a 100-TQFP surface mount package and operates over -40°C to +85°C temperature range. With its picoPower technology, it achieves active current consumption as low as 90 µA/MHz, making it suitable for battery-powered and energy-sensitive designs.
