Memory IC Procurement Notes

Verify the specific suffix 'XHI' against the manufacturer's official ordering guide to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with the target system's voltage levels, as this part requires a 1.65V to 2.0V supply. Cross-reference the datasheet revision to confirm command set and electrical characteristics match your design requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 128M-bit capacity is required with strict low-voltage constraints between 1.65V and 2.0V. The FO-USON8 package offers a small footprint suitable for space-constrained designs. Consider this part if high-speed Quad SPI or QPI interfaces are needed for efficient code execution. Evaluate the need for hardware write protection and security register features for your specific application security model.

Memory IC FAQ

What is the function of the HOLD#/RESET# pin?

The HOLD#/RESET# pin serves a dual function determined by the HOLD/RST bit in Status Register No. 3. When held low, it acts as a HOLD pin to pause serial communication. When held high, it functions as a RESET# pin to reset the device to standby mode.

How does the Quad Enable (QE) bit affect operations?

The QE bit must be set to 1 to enable Quad SPI and QPI modes. When QE is 0, the device operates in Standard or Dual SPI mode, and the HOLD#/RESET# pin retains its dedicated control functions rather than acting as a bidirectional I/O pin.
