Memory IC Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with system voltage levels between 2.3V and 3.6V. Check for moisture sensitivity handling requirements during assembly. Confirm RoHS compliance status if required by regional regulations.

Memory IC Selection Notes

Select this component when a compact 8-land USON package is required for space-constrained designs. Consider the 80MHz clock speed for applications demanding fast sequential reads. Evaluate the security features if unique identification or protected boot code storage is necessary. Ensure the host controller supports the required SPI modes and command sets.

Memory IC Part Context

This part belongs to the MX25V series of Serial NOR Flash memories. It shares architectural similarities with other 16M-bit variants but differs in physical packaging. The USON package offers a smaller footprint compared to SOP or WSON options within the same family.
