Memory IC Procurement Notes

Verify the specific package variant required, as the datasheet lists SOP-8, WSON, and USON options. Confirm temperature grade availability against project requirements. Ensure ordering suffixes match exact electrical and mechanical specifications. Cross-reference manufacturer part numbers with distributor listings to confirm authenticity and revision status before finalizing procurement.

Memory IC Selection Notes

Select this component when a 64M-bit capacity is needed with high-speed Quad SPI interface capabilities. Consider the operating voltage range of 2.7V to 3.6V for compatibility with host system power rails. Evaluate the need for hardware write protection if security against accidental modification is critical. Check available package types to ensure fit within the target PCB layout constraints.

Memory IC Part Context

This part belongs to the BY25Q series of SPI NOR Flash memories from BYTe Semiconductor. The series includes various densities such as 16M-bit, 32M-bit, and 128M-bit variants.
