ATSAMD21E18A-AUT Typical application Circuitry

ATSAMD21E18A-AUT

The ATSAMD21E18A-AUT is a powerful 32-bit ARM Cortex-M0+ microcontroller from Microchip, used extensively in a variety of applications ranging from IoT devices to embedded systems. This guide will walk you through the process of setting up a generic circuit connection for the ATSAMD21E18A-AUT, considering its 32-pin TQFP package.

1. Power Supply and Grounding:

- Pin 6 (DIANA), Pin 13 (VD DIN), and Pin 17 (RADIO): Connect to the power supply. The recommended supply voltage is typically 3.3V.

- Pin 7 (SANA), Pin 14 (GND), and Pin 18 (GND): These are the ground pins and should be connected to your system's ground.

- To lower noise in your circuit, use decoupling capacitors next to the power supply pins.

2. Reset and Oscillator:

- Pin 5 (RESET): Connect to a normally high pull-up resistor and a momentary push button to ground. Pressing the button will pull this pin low, resetting the microcontroller.

- Pins 2 (XIN32) and 3 (XOUT32): If your application requires a real-time clock (RTC), connect a 32.768 kHz crystal across these pins.

- Pins 8 (PA00/IN) and 9 (PA01/OUT): These are used for an external oscillator. If one is needed for your application, connect it across these pins.

3. Digital I/O and Peripherals:

- Pins 1, 4, 10-12, 15-16, 19-32: These pins serve as the general purpose I/O pins. They can be configured for other functionalities such as PART, SPI, I2C, PWM, ADC, and others based on the application's need.

4. Programming the Device:

- The Serial Wire Debug protocol may be used to program the ATSAMD21E18A-AUT. Connect your SWD programmer to the SWCLK (Pin 31) and SDIO (Pin 30) pins.

Always consult the ATSAMD21E18A-AUT data sheet for a thorough understanding and complete capabilities of the microcontroller and its pin configuration. Please be advised that some peripherals and functionality could need extra connections or components.
