A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the layout symmetrical and avoid vias under the IC. Use a 10nF decoupling capacitor between VDD and GND, and a 100nF capacitor between VBAT and GND.
Ensure good thermal conductivity by using a heat sink or a thermal pad on the exposed pad of the IC. Keep the device away from heat sources and ensure good airflow around the device.
Power up the device in the following sequence: VBAT, VDD, and then the clock signal. Ensure VBAT is powered up before VDD to prevent latch-up.
Use ESD protection devices such as TVS diodes or ESD arrays on the I/O lines. Ensure the ESD protection devices are rated for the maximum voltage and current of the I/O lines.
The recommended clock signal frequency is between 10 kHz to 100 kHz, and the amplitude should be between 0.5V to 1.5V peak-to-peak.
