Memory IC FAQ

What is the function of the WP#/ACC input pin?

The WP#/ACC pin serves dual purposes: it disables program and erase functions in outermost sectors when held low, and accelerates programming throughput by placing the device in unlock bypass mode when high voltage is applied.

How does the Secured Silicon Sector enhance security?

It provides a 128-word/256-byte region that can be programmed and locked at the factory or by the customer to store permanent, secure identification information such as an Electronic Serial Number.
