Low-Power, 32-bit Cortex-M0+ MCU with Advanced Analog and PWM

The SMARTSAM D21 series consists of low-power microcontrollers powered by the 32-bit ARM Cortex M0+ processor. With pin counts from 32 to 64, it offers up to 256KB Flash and 32KB SRAM. These devices run at a max frequency of 48MHz and achieve 2.46 CoreMark MHz. They allow for easy and intuitive migration due to identical peripheral modules, hex-compatible code, linear address maps, and pin-compatible paths within the series. All devices come with smart and flexible peripherals, an Event System for signaling between peripherals, and support for capacitive touch interfaces like buttons, sliders, and wheels.

Using the SMARTSAM D21 is quite straightforward. First, connect it to your system according to the pin - out diagram. You can start programming it using the hex - compatible code. When designing your project, take advantage of the intelligent peripherals and the Event System to make your device more efficient. For the capacitive touch interfaces, you can customize the buttons, sliders, or wheels to fit your user interaction needs. As for maintenance, keep the device in a clean and dry environment. Avoid exposing it to extreme temperatures or humidity. If you are using it in a high - vibration environment, make sure it is properly secured. When programming, always double - check your code to prevent any errors that could damage the device.
