Memory IC Procurement Notes

Verify the specific package suffix 'LIGR' against the manufacturer's official ordering information table to confirm pinout and physical dimensions. Ensure compatibility with the 1.65V-2.0V supply range. Confirm that the required interface modes (Standard, Quad, or DTR) are supported by the host controller. Check for any specific revision history updates that may affect command sets or electrical characteristics.

Memory IC Selection Notes

Select this component when a 256M-bit density is required with support for DTR Quad I/O operations. It is suitable for designs constrained by a 1.65V to 2.0V power supply domain. Consider its uniform sector architecture for simplified memory management. Evaluate the need for hardware reset functionality via the dedicated RESET# pin. Ensure the system can handle the specific timing requirements for DTR mode if maximum speed is utilized.

Memory IC Part Context

The GD25LB256E series belongs to GigaDevice's family of uniform sector serial flash memories. This series is designed to offer high performance and low power consumption for various embedded applications. The device supports multiple interface modes to balance speed and pin count flexibility. It is part of a broader portfolio that includes different densities and voltage options to meet diverse market needs.

Memory IC Replacement Considerations

Check for other GD25LB256E variants with different package suffixes such as EYAGR or EFIRR if the current package is unavailable. Verify that substitute parts maintain the same 1.65V-2.0V operating voltage and DTR support. Ensure pin compatibility for SOP16 or WSON8 packages if switching between package types within the same series.

Memory IC FAQ

What is the maximum data transfer rate supported by the GD25LB256ELIGR?

The device supports DTR Quad I/O mode, which allows data transfer at speeds up to 832 Mbits/s.

How does the hardware write protection work on this device?

Hardware write protection is enabled by pulling the WP# pin low, which locks the Status Register and prevents modification of the Block Protect bits.

Is the GD25LB256ELIGR compatible with standard SPI controllers?

Yes, it supports Standard SPI mode using SCLK, CS#, SI, and SO signals, ensuring compatibility with standard SPI controllers.
