Memory IC FAQ

What is the function of the WP# pin?

The WP# pin provides hardware protection for the first or last 16 Kbyte sector, depending on the boot configuration, preventing program or erase operations when held at a logic low level.

How does the device indicate program or erase completion?

Completion can be detected via the RY/BY# pin for hardware status monitoring or by reading Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2) through software polling.
