Microchip Technology's ATSAMR21G16A-MU is a 32-bit RISC microcontroller featuring an ARM Cortex-M0 CPU operating at up to 48MHz. This component offers 64KB of FLASH program memory and 8KB of data RAM. Connectivity options include I2C, LIN, SPI, UART, USART, and USB interfaces. Integrated peripherals include 12 DMA channels, 6 timers, 2 comparators, a Real-Time Clock (RTC), Watchdog Timer (WDT), Brown-Out Detector (BOD), and Power-On Reset (POR). It also incorporates an 8-channel, 12-bit Analog-to-Digital Converter (ADC) and PWM channels. The ATSAMR21 series microcontroller operates within a supply voltage range of 1.8V to 3.6V and a temperature range of -40°C to 85°C. Packaged in a 48-pin QCCN (S-XQCC-N48) square chip carrier with a 0.5mm terminal pitch, this device is suitable for applications in industrial automation, consumer electronics, and wireless sensing.
