Memory IC Procurement Notes

Verify the specific suffix 'R' against official documentation to confirm packaging details such as tape and reel specifications. Ensure the ordering code matches the exact voltage range and temperature grade required for your design. Cross-reference the manufacturer's latest datasheet for any updates on pin configurations or electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when an 8 Mbit capacity is required with high-speed Quad SPI support. It is suitable for designs needing flexible sector sizes and robust write protection features. Consider the 8-SOP package constraints and ensure the host system supports the necessary SPI modes and voltage levels between 2.7 V and 3.6 V.

Memory IC Part Context

This part belongs to the BY25Q80ES series of SPI NOR Flash memories from BYTe Semiconductor. It is designed for general-purpose non-volatile storage applications requiring reliable data retention and high endurance. The series supports various package options and interface speeds to accommodate different system performance requirements.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the BYTe Semiconductor portfolio that match the 8 Mbit density and 8-SOP package. Verify compatibility with existing firmware if replacing with similar parts from other manufacturers, ensuring SPI command set alignment.
