Design Notes
Ensure proper decoupling on all power supply pins. Place a 100 nF ceramic capacitor as close as possible to each VDD/VDD_HV pin, and a 10 uF bulk capacitor on the main supply. This minimizes voltage transients and ensures stable operation.
For the LQFP-144 package, use a 4-layer PCB with dedicated power and ground planes. Route high-speed signals away from analog inputs to reduce noise coupling. Follow STMicroelectronics layout guidelines for optimal EMC performance.
Do not exceed the absolute maximum ratings for supply voltage and I/O pins. Ensure the reset circuit is properly designed to avoid spurious resets. For safety-critical applications, implement the lockstep mode and use the built-in self-test (BIST) during startup.
