Memory IC Procurement Notes

Verify the specific package variant (USON-8 dimensions) and temperature grade against the datasheet Rev 2.7. Confirm the ordering suffix matches the required pin configuration and moisture sensitivity level. Ensure the supply voltage requirements align with the 1.65V to 2.0V range specified for this BL series part.

Memory IC Selection Notes

Select this component for designs requiring ultra-low voltage operation between 1.65V and 2.0V. It is suitable for applications needing small form factor packaging like USON-8. Consider the 10k program-erase cycle endurance and 20-year data retention when evaluating long-term reliability for consumer or industrial use cases.

Memory IC Part Context

This part belongs to the BY25Q20BL series of 2M-bit SPI NOR Flash memories. It is designed for high-volume consumer applications where code execution occurs from external RAM. The BL designation indicates the specific low-voltage operating range compared to other variants in the BY25Q family.

Memory IC Replacement Considerations

Check for BY25Q20BLYIG(T) as a potential tape-and-reel alternative if different packaging is needed. Verify compatibility with other 2M-bit SPI NOR flashes from BYTe or competitors, ensuring voltage levels and pinouts match.
