Memory IC Procurement Notes

Verify the specific ordering suffix 'ZXI' corresponds to the 32-pin TSOP Type I package configuration. Confirm that the component meets RoHS compliance standards as indicated in distributor listings. Ensure the procurement channel provides original manufacturer documentation to validate the Industrial temperature grade and speed bin specifications prior to integration.

Memory IC Selection Notes

Select this component for designs requiring low-power SRAM with a wide voltage supply range. The TSOP Type I package is appropriate for surface-mount applications where space efficiency is balanced with standard pin spacing. Consider the 45 ns speed grade against system timing requirements and ensure compatibility with existing logic levels for CE, OE, and WE signals.

Memory IC Part Context

This part belongs to the MoBL (More Battery Life) SRAM family, designed specifically for portable applications. It is pin-compatible with previous generations like the CY62128DV30, facilitating design upgrades. The device leverages advanced CMOS circuitry to optimize the trade-off between speed and power dissipation, targeting extended battery life in mobile devices.

Memory IC Replacement Considerations

The CY62128EV30LL-45SXI serves as a functional alternative offering identical electrical characteristics but packaged in a 32-pin SOIC format. Designers must verify footprint compatibility when substituting packages. Other speed grades or voltage variants within the same family may require schematic adjustments.
