Memory IC Procurement Notes

Verify the specific suffix 'TJGR' against official manufacturer documentation to confirm the exact package dimensions and tape & reel specifications. Ensure that the industrial temperature grade (-40°C to +105°C) aligns with your system's environmental requirements. Cross-reference the ordering information section of the datasheet to validate availability and current production status.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with support for high-speed Quad SPI operations. It is suitable for designs needing robust data protection via hardware WP# pin or software commands. Consider the SOP-8 150mil package constraints for PCB layout. Verify compatibility with the host controller's SPI clock frequency limits and voltage levels.

Memory IC Part Context

This part belongs to the GD25Q16C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The series offers various package options including SOP, USON, and WSON formats. The GD25Q16CTJGR specifically denotes the industrial temperature variant in the SOP-8 150mil package, designed for reliable performance in demanding environments.

Memory IC Replacement Considerations

Check for other GD25Q16C variants with different suffixes if package or temperature requirements change. Ensure any substitute maintains the same 16M-bit density and Quad SPI support. Verify that the replacement part supports the same command set and voltage range.
