Memory IC Procurement Notes

Verify the specific suffix 'FYIGR' against the official manufacturer datasheet to confirm pinout, temperature grade, and tape-and-reel specifications. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the selected variant matches the required operating voltage and interface compatibility for your target design.

Memory IC Selection Notes

Select this part when a 1 Gbit density is required with a 1.65 V to 2 V supply constraint. The WSON-8 package suits space-constrained designs. Verify that the system supports the necessary SPI modes (Dual/Quad/QPI) to utilize the 133 MHz clock speed effectively. Check if automotive qualification is needed, as standard variants may differ from AEC-Q100 certified parts.
