ATSAMS70Q21A-AN Typical application Circuitry

ATSAMS70Q21A-AN

ATSAMS70Q21A-AN is a high-performance, ultra-low-power ARM Cortex-M7 based microcontroller unit (MCU) from Microchip's SAM S70 family. It is designed for general-purpose applications running at up to 300MHz.

This MCU comes with up to 2MB dual-bank Flash and up to 384KB SRAM with ECC, along with a rich set of peripheral interfaces that include USB, UART, SPI, SDIO/SD/MMC, TWI, and SMC. Thanks to its rich feature set and robust processing capabilities, it is well suited for an extensive range of applications, such as industrial automation, IoT devices, and embedded control systems.

As an example, let's examine how the ATSAMS70Q21A-AN might be deployed in an embedded control system.

1. Power Supply Pins: The MCU is powered by connecting VDDCORE (Pin 4), VDDIO (Pins 21, 22, 54, 70), and VDDOUT (Pin 6) to a 3.3V power supply, while the GND (Pins 1, 2, 3, 19, 20, 52, 53, 69) pins should be connected to ground. The VDDIN (Pin 5) pin is used to supply the internal regulator and should also be connected to the power supply.

2. Digital I/O Pins: The ATSAMS70Q21A-AN has a large number of digital I/O pins for interfacing with other digital devices. For example, PC0 to PC31 (Various Pins) can be connected to digital sensors or other peripherals for control and communication.

3. Analog Input Pins: This MCU features an analog-to-digital converter (ADC). The ADC input pins (PA17-PA20, Pin 97-100) can be connected to sensors to read analog data.

4. Communication Pins: The ATSAMS70Q21A-AN supports multiple communication protocols. The SPI interface, for instance, includes SPI0_MISO (PB0, Pin 58), SPI0_MOSI (PB1, Pin 59), SPI0_SPCK (PB2, Pin 60), and SPI0_NPCS0 (PB3, Pin 61).

5. Programming Pins: To program the MCU, the SWDIO (Pin 109) and SWCLK (Pin 110) pins are used.

In designing a circuit with the ATSAMS70Q21A-AN, some considerations include:

1. Supply Voltage: Ensure the supply voltage is within the recommended range to prevent potential damage to the MCU.

2. Decoupling Capacitors: The placement of decoupling capacitors near the supply voltage pins is advisable to reduce high-frequency noise in the supply voltage.

3. Input/Output Voltage Levels: The voltage levels of all inputs and outputs should be within the specified limits of the MCU to prevent damaging the device or connected peripherals.

4. Clock Selection: The MCU has multiple clock options. To optimize power and performance, pick the one that best fits your unique needs.

5. Thermal Management: Adequate thermal management should be designed to avoid overheating, which can affect the MCU's performance and reliability.

6. Protection Measures: Implementing protection measures like transient-voltage-suppression diodes can help protect the MCU from electrostatic discharge or other transient voltages.

In summary, the ATSAMS70Q21A-AN is a robust, high-performance microcontroller that can be used in a wide range of applications. It's essential to consider factors like supply voltage, decoupling capacitors, I/O voltage levels, clock selection, thermal management, and protection measures when designing a circuit with this MCU. As always, the most precise and comprehensive information should be found in the ATSAMS70Q21A-AN datasheet.
