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 90µA/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 1.5µA. The BACKUP mode further reduces power usage to less than 0.9µA 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 I²C. 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°C to 85°C, the ATSAM4LC4BA-AUR is designed for applications that demand reliability and efficiency in power-sensitive environments.
