ATSAMV71Q21B-AAB Typical application Circuitry

ATSAMV71Q21B-AAB

The ATSAMV71Q21B-AAB is a high-performance microcontroller from Microchip, based on the 32-bit ARM Cortex-M7 RISC processor. It includes a floating point unit (FPU) for high-precision computing and a DSP instruction set for digital signal processing.

Functional Description

With an operation frequency of up to 300 MHz, the ATSAMV71Q21B-AAB provides ample power for demanding applications. Its large on-chip memory includes 2MB Flash and 384KB SRAM. Furthermore, it offers a wide range of high-speed communication interfaces, including Ethernet MAC, USB, and CAN, as well as 16-bit ADCs and 12-bit DACs.

Typical Applications

Typical applications of the ATSAMV71Q21B-AAB include automotive infotainment, advanced media players, high-quality audio systems, and industrial automation systems.

Specific Circuit Connection

Let's describe a basic circuit connection of ATSAMV71Q21B-AAB for an embedded control system application.

1. Power Supply: Connect VDDCORE (Pin 64) and VDDIO (Pins 49, 79) to the 3.3V power supply, and VSS (Pins 50, 80) to the ground.

2. System Oscillator: Connect XIN32 and XOUT32 (Pins 85 and 86) to a 32.768 kHz crystal oscillator. These are the input and output pins for the 32 kHz crystal oscillator, which is often used for real-time clock (RTC) functions.

3. Main Clock: Connect XIN and XOUT (Pins 2 and 3) to a higher frequency crystal, such as 12 MHz. This is the main clock source for the microcontroller.

4. Reset Pin: Connect the NRST (Pin 88) to a reset switch, typically through a resistor. This pin is used to manually reset the microcontroller.

5. Programming Interface: Connect TMS and TCK (Pins 77 and 78) to the JTAG programmer's corresponding pins. These pins are utilized for microcontroller programming and debugging.

6. Digital I/O: Connect GPIO pins (PA0 to PA31, PB0 to PB31) as required by your application, such as switches, LEDs, or other peripherals.

Considerations in Design

When working with ATSAMV71Q21B-AAB , some key factors need to be considered:

1. Power Supply Decoupling: Add decoupling capacitors close to the VDDCORE and VDDIO pins to ensure a stable power supply.

2. Clock Stability: Make sure to use appropriate load capacitors with the crystal oscillators for stable oscillation.

3. Reset Circuitry: It's advisable to include a pull-up resistor and capacitor in the reset circuitry to prevent erroneous resets.

4. Programming Interface: Make sure the JTAG programmer and the microcontroller's JTAG interface are compatible.

5. Thermal Management: Ensure proper heat dissipation measures, such as heat sinks or thermal vias, as this chip can generate significant heat at full load.

In conclusion, the ATSAMV71Q21B-AAB is a robust microcontroller suitable for a wide range of high-performance applications. Proper considerations around the power supply, clock stability, reset circuitry, programming interface, and thermal management are critical to the successful implementation of designs using this chip.
