Memory IC FAQ

What is the maximum clock frequency for Quad Read operations?

The maximum clock frequency for Quad Read (QREAD) is 133MHz when using 10 dummy cycles.

How does the Block Lock Protection work?

Block Lock Protection uses BP0-BP3 and T/B status bits to define specific areas of the memory as read-only, protecting them from program and erase instructions.
