Memory IC FAQ

What is the maximum clock frequency for the FSTRD command?

The FSTRD command supports a maximum clock frequency of 40 MHz when the supply voltage is between 2.7 V and 3.6 V.

How does the HOLD pin function during serial communication?

The HOLD pin allows interruption of serial input/output without deselecting the chip. When held low, SO becomes High-Z and SCK/SI inputs are ignored until the pin returns high.

What is the data retention period at elevated temperatures?

Data retention is guaranteed for at least 10 years at an ambient temperature of +85°C, 95 years at +55°C, and over 200 years at +35°C.
