32-bit microcontroller ATSAMC21 series

general purposeARM

5V SAM C Microcontrollers Based on Arm® Cortex®-M0+ 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. Key Features 2.7V–5.5V Operating Voltage Ensures best possible signal-to-noise ratio and robustness in term of noise immunity, EMC, ESD and latch up QTouch® Technology Peripheral Touch Controller Offers built-in hardware support for buttons, sliders, wheels and QTouch Surface, and supports both mutual- and self-capacitive touch without the need for external components Delivers superb sensitivity and noise tolerance, as well as self-calibration, making any user tuning superfluous Peripheral Flexibility Innovative serial communication module (SERCOM) is fully software-configurable to handle I2C, USART/UART, SPI, RS485 and LIN communications Multiple SERCOM modules can be used to tailor the peripheral mix precisely to your application CAN Bus The SAM C21 series provides two Controller Area Network (CAN) modules supporting CAN 2.0A/B and CAN FD 1.0 DMA The SAM C20 series features a six-channel Direct Memory Access (DMA) controller supporting both memory and peripheral data transfers, while the SAM C21 features a 12-channel DMA controller Scalability
