Write-Protect (WP)

The write-protect input, when connected to GND, allows normal write operations. When the WP pin is connected

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.
