The ATSAML10D15A-MU with ARM Microcontrollers MCU is manufactured by Microchip, and it is a 32-bit ARM Cortex-M23 device with 32KB Flash, 8KB SRAM, and 32 MHz operating frequency. It features a Peripheral Touch Controller (PTC) module for capacitive touch functions, a Serial Communication Module (SERCOM) for USART, I2C and SPI communication, an Analog-to-Digital Converter (ADC) with up to 12-bit resolution, a low-power Digital-to-Analog Converter (DAC) with up to 8-bit resolution, and an operational amplifier unit (OPAMP) for signal conditioning. Additionally, it includes a power-efficient switched capacitor converter (AC) to generate an internal voltage for the flash| SRAM memory, and several advanced security features such as secure boot and secure ignorance.
