Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage range (1.7V-2.0V vs 2.7V-3.6V), package type (WSON8 or TFBGA), and industrial grade (-40°C to 85°C). Confirm that the 'E' designation aligns with the 2K+128B page size specification. Ensure compatibility with host controller SPI modes if DTR or Quad I/O features are utilized. Cross-reference the manufacturer's latest product list for availability and form factors.

Memory IC Selection Notes

Select this component when a 4Gb density with 2K+128B page size is required. Choose the 1.8V variant for low-power applications and the 3.3V variant for standard logic levels. Consider the WSON8 package for smaller footprints or TFBGA for higher pin density needs. Ensure the host system supports the desired SPI mode (Standard/Dual/Quad/DTR) to leverage performance benefits. Verify internal ECC requirements match the application's error tolerance.
