PIN NAME

NUMBER

PIN DESCRIPTION

VIN 35

Supply voltage input

Connect the 5V ±10% supply to VIN. Bypass VIN to GND with a 10µF or greater ceramic capacitor

VDD 36

2.5V internal LDO regulator output

VDD is the output of the internal regulator and powers internal logic. Bypass VDD to GND with a 1µF

ceramic capacitor

EP Exposed Pad

Power ground

Connect the exposed pad, EP, to system GND and to the GND pins using short, wide traces
