Memory IC Procurement Notes

Verify the specific suffix '2GLI' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing Microwire bus protocols in the target design. Confirm that the 1.8V to 5.5V supply range aligns with the system power rails. Check for any recent revisions to the part number that may affect pinout or electrical characteristics.

Memory IC Selection Notes

Select this component when a small, serial EEPROM with Microwire interface is required. It is suitable for applications needing moderate density with high reliability. Consider the 1.8V minimum voltage if designing for low-power systems. Verify that the 8-pin SOIC package fits the PCB layout constraints. Compare against I2C alternatives if bidirectional communication is needed.

Memory IC Part Context

This part belongs to the GT93C46A series of Microwire serial EEPROMs from Giantec Semiconductor. The series offers various memory densities and organization options. The GT93C46A specifically provides 1K-bit capacity. It is designed for cost-sensitive applications requiring reliable non-volatile storage.
