Memory IC Procurement Notes

Verify the specific package suffix 'OIG' against official datasheet tables, as standard listings typically specify SOP or TSSOP variants. Confirm temperature grade requirements match commercial or industrial ratings. Ensure ordering documentation aligns with manufacturer specifications for the exact part number variant.

Memory IC Selection Notes

Select this component when dual SPI interface support is required for higher throughput without Quad I/O complexity. Verify that the 16Mbit density fits the application's code and data storage needs. Check if the 2.7V minimum voltage meets the system's power rail capabilities. Consider the 8-pin package options available for PCB layout constraints.

Memory IC Part Context

This part belongs to the BYTe Semiconductor BY25D16 series of 16M-bit SPI NOR Flash memories. The series offers various package options including SOP and TSSOP. It is designed for general-purpose non-volatile storage applications requiring reliable performance and flexible protection mechanisms.

Memory IC Replacement Considerations

Check for direct pin-to-pin compatible parts from other manufacturers offering similar 16Mbit density and Dual SPI support. Verify electrical characteristics such as voltage range and clock speeds match the original design requirements.
