Last modified by Microchip on 2023/11/09 09:01

The Microchip SAM D21 device has the following peripherals:

  • Analog-to-Digital Converter (ADC): This peripheral allows the device to convert analog signals into digital signals for processing.
  • Digital-to-Analog Converter (DAC): This peripheral allows the device to convert digital signals into analog signals for output.
  • Serial Communication Interfaces (SERCOM): This peripheral allows the device to communicate with other devices using various serial communication protocols such as I2C, SPI, and UART.
  • Universal Serial Bus (USB): This peripheral allows the device to communicate with a computer or other USB-enabled device.
  • Timer/Counters (TC): This peripheral allows the device to measure time intervals and generate periodic signals.
  • Pulse Width Modulation (PWM): This peripheral allows the device to generate analog signals by varying the duty cycle of a digital signal.
  • Event System: This peripheral allows the device to trigger actions based on events occurring in other parts of the system.
  • Direct Memory Access (DMA): This peripheral allows the device to transfer data between memory and peripherals without using the CPU.
  • Peripheral Touch Controller (PTC): This peripheral allows the device to detect touch inputs on capacitive touch sensors.
  • Real-Time Counter (RTC): This peripheral allows the device to keep track of time even when the device is in a low-power state.
  • External Interrupt Controller (EIC): This peripheral allows the device to respond to external events by interrupting the CPU.
  • Watchdog Timer (WDT): This peripheral allows the device to reset itself if it becomes unresponsive or enters an unexpected state.
  • System Control and Reset (SYSCTRL): This peripheral allows the device to control various system-level functions such as power management and clock configuration.
  • Clock Control (GCLK): This peripheral allows the device to generate and control various clock signals used by other peripherals.

In summary, the Microchip SAM D21 device has a wide array of peripherals that enable it to perform a variety of functions. These peripherals include analog and digital signal processing, communication interfaces, timers and counters, touch sensing, power management, and more.
