Procurement Notes

Verify the specific suffix 'BT' against official documentation to confirm exact packaging and environmental compliance details. Ensure the selected variant matches the required operating temperature range and voltage specifications for your design. Cross-reference the datasheet revision history for any recent manufacturing changes or updates.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. Consider the 32-byte page size for efficient sequential writes compared to smaller page variants. Verify compatibility with the host microcontroller's SPI mode and voltage levels before integration into the circuit design.

Part Context

This part belongs to the 25LC160A/B family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including SPI compatibility and similar instruction sets. Variants differ primarily in page size, temperature ratings, and physical packaging options available for different deployment needs.

Replacement Considerations

Compatible substitutes include other 25LC160 variants with matching SPI interfaces and voltage ranges. Verify equivalent page sizes and temperature ratings when selecting alternatives to ensure functional parity in existing designs.
