A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the IC.
Use a dedicated SPI bus with a clock frequency of 1-10 MHz, and ensure proper signal termination and shielding to minimize electromagnetic interference (EMI).
Choose a power supply with a low output voltage ripple (< 1%), a high power supply rejection ratio (PSRR), and a low equivalent series resistance (ESR) capacitor.
Use the device's low-power modes (e.g., sleep mode), reduce the clock frequency, and minimize the number of active circuits. Also, consider using a low-dropout regulator (LDO) for power supply.
Ensure proper PCB layout, use shielding, and follow good EMC design practices. Also, consider using a common-mode choke and a ferrite bead to reduce electromagnetic interference (EMI).
