Memory IC Procurement Notes

Verify the specific suffix 'BJRY' against the manufacturer's official ordering information table to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm that the TFBGA-24 package dimensions match the PCB footprint design. Check for any specific automotive or industrial grade certifications if required by the application environment.

Memory IC Selection Notes

Select this component when a high-density 2G-bit capacity is required with support for fast read speeds up to 720Mbits/s in DTR mode. It is suitable for designs needing robust data protection mechanisms including OTP lockable security registers. Consider this part for applications where low standby current and long data retention are critical. Ensure the host controller supports the desired interface modes (SPI/QPI/DTR) for optimal performance.

Memory IC FAQ

What is the maximum data transfer rate supported by the GD55B02GEBJRY?

The device supports data transfer rates up to 532Mbits/s in Quad I/O and QPI modes, and up to 720Mbits/s in DTR Quad I/O mode.

How does the hardware write protection work on this device?

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

Can the GD55B02GEBJRY operate in both 3-byte and 4-byte address modes?

Yes, the device supports both 3-byte and 4-byte address modes. The Extended Address Register allows segmentation in 3-byte mode, while 4-byte mode provides full array access without segmentation limits.
