Memory IC Procurement Notes

Verify the specific package variant (SOP8 or USON8) required for your design, as the base model covers multiple packages. Confirm that the ordering suffix matches the desired physical footprint and tape/reel specifications. Ensure compatibility with your system's voltage levels, as the device requires a 2.7V to 3.6V supply. Check for any regional distribution restrictions or lead time variations before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity is sufficient for application requirements. Choose based on the preferred package type, either SOP8 or USON8, depending on board space constraints. Consider the Dual Output capability if higher read speeds are needed without increasing clock frequency. Ensure the design accommodates the 2.7V to 3.6V operating voltage range and utilizes the available write protection features for data integrity.

Memory IC Part Context

This part belongs to the GD25D40E/20E series of Uniform Sector Standard and Dual Serial Flash memories. The series offers densities of 4 Mbit and 2 Mbit, sharing similar command sets and architectural features. It is designed for applications requiring reliable code execution and data storage with flexible protection options.
