Memory IC Procurement Notes

Verify the specific suffix JRR against official datasheets to confirm the SOP-16 package and +105°C temperature rating. Confirm RoHS compliance status through manufacturer documentation. Check for any regional distribution restrictions or shipping limitations before ordering. Ensure compatibility with existing board designs regarding pinout and voltage levels.

Memory IC Selection Notes

Select this part when an SOP-16 package is required for 1 Gbit capacity. Choose over other variants if the +105°C operating temperature is necessary. Verify that the DTR mode support aligns with controller capabilities. Compare against GD55B01GEFIRR if lower temperature requirements allow for cost optimization.

Memory IC Part Context

This component belongs to the GD55B series of NOR flash memories from GigaDevice. The series offers densities ranging from 2Mb to 2Gb. It is designed for high-performance code execution and data storage applications requiring reliability and speed.

Memory IC Replacement Considerations

GD55B01GEFIRR is a similar variant with the same electrical specifications but limited to an 85°C operating temperature range. Verify package compatibility and thermal requirements before substitution.
