The ATSAM4LS4BA-AU is a 32-bit microcontroller from Quarktwin Technology Ltd., based on the ARM Cortex-M4 architecture, operating at frequencies up to 48MHz. It features 256KB of embedded Flash memory and 32KB of SRAM, making it suitable for a variety of applications requiring efficient processing and memory management. This microcontroller incorporates picoPower technology, allowing for ultra-low power consumption with active current as low as 90¬µA/MHz. It supports multiple low-power modes, including WAIT and RETENTION modes, which enable fast wake-up times of less than 1.5¬µs while maintaining RAM and logic retention. The BACKUP mode further reduces power consumption to below 0.9¬µA. The ATSAM4LS4BA-AU includes a comprehensive set of peripherals, such as a USB 2.0 device and embedded host, a capacitive touch module supporting up to 32 buttons, and various serial communication interfaces like USART, SPI, and I¬=C. Additionally, it features an advanced encryption system (AES) for secure data handling and a 16-channel ADC for analog signal processing. With a wide operating voltage range of 1.68V to 3.6V and available in multiple package types, including TQFP and QFN, the ATSAM4LS4BA-AU is designed for industrial applications with an operating temperature range of -40¬8C to 85¬8C. This microcontroller is well-suited for projects that require a balance of performance, power efficiency, and extensive peripheral support.
