Memory IC Procurement Notes

Verify the specific suffix 'TJGR' against official manufacturer documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure that the required operating temperature range aligns with the industrial grade rating associated with this part variant. Cross-reference the datasheet revision to confirm command set compatibility before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity is required with support for high-speed quad I/O operations. The SOP-8 package is suitable for surface-mount assembly where space constraints allow for its footprint. Consider the industrial temperature range if the application environment exceeds commercial limits. Verify that the host controller supports the necessary SPI modes and dummy cycle configurations for optimal performance.

Memory IC Part Context

This part belongs to the GD25Q16E series of uniform sector dual and quad serial flash memories. The series offers consistent electrical characteristics across various package options including USON and WSON variants. The 'E' designation indicates the specific generation supporting up to 133 MHz clock speeds. All members share the same core memory organization and command set architecture.

Memory IC FAQ

How does the Quad Enable bit affect the HOLD# pin function?

When the Quad Enable bit is set to 1, the HOLD# pin functions as a dedicated bidirectional I/O pin (IO3). The hold function is disabled in this state. To use the hold feature, the Quad Enable bit must be 0.

What is the purpose of the Dummy Configuration bit in Status Register 2?

The Dummy Configuration bit selects the number of dummy cycles inserted between the address phase and data output phase during fast read commands. This ensures proper timing alignment at higher clock frequencies.
