Memory IC FAQ

What is the maximum clock frequency for Dual Output Fast Read?

The maximum clock rate for Dual Output Fast Read is 108MHz.

How does the hardware write protection work?

Hardware protection is enabled by driving the /WP pin low, which locks the Block Protect bits in the Status Register against modification.

What is the typical data retention period?

The typical data retention period is 20 years.
