• Boot code storage for embedded applications.

Memory IC Procurement Notes

Verify the specific package variant (SOP-8, USON-8, or WSON-8) matches the design footprint, as the base part number covers multiple physical packages. Confirm the voltage range (1.65V-2.0V) aligns with the target system's power rails. Ensure the Quad Enable (QE) bit configuration is compatible with the host controller's interface support. Check for any specific ordering suffixes that may denote tape-and-reel quantities or specific lead-free certifications if required by manufacturing processes.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.0V) NOR flash solution is required with high-speed Quad I/O or QPI interface support. It is suitable for designs needing uniform sector erase capabilities and robust data protection features including hardware write protect and security registers. Consider the SOP-8, USON-8, or WSON-8 package options based on board space constraints and thermal requirements. Ensure the application does not require higher voltage levels or larger densities beyond 8 Mbit.

Memory IC Part Context

Memory IC FAQ

How does the Quad Enable (QE) bit affect the HOLD# and WP# pins?

When the QE bit is set to 1, the HOLD# and WP# pins function as bidirectional I/O pins (IO3 and IO2) for Quad SPI operations, disabling the standard HOLD and Write Protect functions.

What is the purpose of the CMP bit in the Status Register?

The Complement Protect (CMP) bit provides flexibility for array protection by altering how the Block Protect (BP4-BP0) bits define protected areas, allowing for different top/bottom block protection schemes.
