Microchip Technology, Inc. Microcontrollers ATSAM4LC4BA-AUR

The ATSAM4LC4BA-AUR 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 data handling and processing capabilities. This microcontroller incorporates picoPower technology, allowing for ultra-low power consumption with active current down to 90¬µA/MHz. It supports multiple power-saving modes, including WAIT and RETENTION modes, which provide fast wake-up times and very low power consumption, as low as 1.5¬µA. The BACKUP mode further reduces power usage to less than 0.9¬µA while maintaining the ability to wake up from external interrupts. The ATSAM4LC4BA-AUR includes a rich 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 including USART, SPI, and I¬=C. It also features an advanced encryption system compliant with AES standards, enhancing security for data transmission. With its compact package options and industrial temperature range of -40¬8C to 85¬8C, the ATSAM4LC4BA-AUR is designed for applications that demand reliability and efficiency in power-sensitive environments.
