The Atmel® | SMART 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. Atmel | SMART SAM C devices are truly differentiated 5V microcontrollers 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.
- Atmel® QTouch® Peripheral Touch Controller — Offers built-in hardware support for buttons, sliders, wheels and proximity, and supports both mutual- and self-capacitive touch without the need for external components. It delivers superb sensitivity and noise tolerance, as well as self-calibration, making any user tuning superfluous.
- Peripheral Flexibility — An innovative serial communication module (SERCOM) is fully software-configurable to handle I2C, USART/UART, SPI, RS485 and LIN communications. With multiple SERCOM modules on a device, you can 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 6-channel DMA controller supporting both memory and peripheral data transfers, while the SAM C21 features a 12-channel DMA controller.
- Scalability — Flash memory densities range from 32KB to 256KB with packages ranging from 32- to 64-pin options.
