Memory IC Procurement Notes

Verify the specific suffix 'RC' against the manufacturer's current datasheet to confirm the exact temperature grade and package variant. Confirm availability status as this part number may be subject to discontinuation or lifecycle changes. Ensure the host system voltage matches the required 4.5V to 5.5V operating range before integration.

Memory IC Selection Notes

Select this component when a 5V logic interface is required for SPI flash memory. The 28-SOIC package is suitable for standard PCB layouts requiring through-hole or wide SMT footprints. Consider the 10 MHz speed limit for high-frequency data transfer requirements compared to faster DataFlash alternatives.

Memory IC Part Context

This device belongs to the broader family of serial NOR Flash memories from Microchip Technology. It provides reliable non-volatile storage for embedded applications requiring byte-level access capabilities via the SPI bus. The 8 Mbit density balances storage needs with cost-effectiveness for mid-range microcontroller systems.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements such as the AT45DB081D series if higher speed or different voltage operation is needed. Verify that any substitute maintains the 28-SOIC package and 5V operating voltage specifications.
