Memory IC Procurement Notes

Verify the specific ordering suffix 'YIGY' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure that the required operating voltage range of 1.65V to 2.0V aligns with your system design constraints before procurement.

Memory IC Selection Notes

Select this component when a 256M-bit density is required with low-voltage operation between 1.65V and 2.0V. Consider the 8-WSON package size if space constraints are critical. Evaluate interface requirements to determine if DTR Quad I/O speeds are necessary for the application.

Memory IC Part Context

Memory IC FAQ

What is the maximum clock frequency supported by the GD25LB256E?

The device supports a maximum clock frequency of 166 MHz for fast read operations.

How does the device handle hardware reset?

The RESET# pin allows the device to be reset by the control. When driven low for a minimum period, it resets the flash to standby mode and clears all volatile bits.
