12-bit microcontroller ATSAMC21 series

general purposeARManalog

The SAM C Arm Cortex-M0+-based microcontroller (MCU) series builds on decades of innovation and experience in embedded Flash microcontroller technology. It not only sets a new benchmark for flexibility and ease of use, but also combines the performance and energy efficiency of an Arm Cortex-M0+ based MCU with an optimized architecture and peripheral set. SAM C devices are truly differentiated 5V MCUs that are ideal for home appliances, industrial control and other 5V applications. SAM C20 devices integrate high-precision 12-bit analog and internal oscillators, five 16-bit timer/counters (SAM C20J and SAM C20G, and three in SAM C20E), 32-bit Real-Time Clock and Calendar (RTCC), real-time performance, peripheral event system and flexible clocking options and sleep modes. The devices also include six (SAM C20J and SAM C20G, four in the SAM C20E) serial communication modules (SERCOMs) that can be configured from the application to act as an USART, UART, SPI and I2C. The series supports button, slider and wheel touch capability without the need for external components. SAM C21 devices integrate high-precision 12-bit analog and internal oscillators, five 16-bit timer/counters, three timer/counters for control applications, 32-bit RTCC, real-time performance, peripheral event system, DMA, temperature sensor, divide and square root accelerator, 16-bit sigma-delta ADC (SDADC) and flexible clocking options and sleep modes. The devices also include up to two CAN interfaces with CAN FD 1.0 support. There are up to eight SERCOMs that can be configured from the application to act as an USART, UART, SPI, I2C, RS485 and LIN bus.
