2.5 Write-Protect (WP)
The write-protect input, when connected to GND, allows normal write operations. When the WP pin is connected
directly to V
CC
, all write operations to the protected memory are inhibited.
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.

2.6 Device Power Supply
The V
CC
pin is used to supply the source voltage to the device. Operations at invalid V
CC
voltages may produce
spurious results and should not be attempted.
