If the pin is left floating, the WP pin will be internally pulled down to GND. However, due to capacitive coupling that

may appear in customer applications, Microchip recommends always connecting the WP pin to a known state. When

using a pull‑up resistor, Microchip recommends using 10 kΩ or less.

Device Power Supply (VCC)

The Device Power Supply (VCC) pin is used to supply the source voltage to the device. Operations at invalid VCC

voltages may produce spurious results and should not be attempted.
