Memory IC Procurement Notes

Verify the specific suffix BLI against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the TFBGA-24 package dimensions align with your PCB footprint. Confirm RoHS compliance status if required by your regional regulations. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations from ISSI before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a serial interface is preferred over parallel to save PCB routing space. The 166 MHz speed offers a balance between performance and power efficiency for mid-range applications. Consider the 2.7V minimum voltage requirement to ensure compatibility with your system's power rails. The TFBGA package is suitable for automated surface-mount assembly processes.

Memory IC Part Context

This part belongs to ISSI's OctalRAM family, which combines the simplicity of SRAM with the density of DRAM. Unlike HyperRAM, OctalRAM uses an SPI-compatible interface. The IS66WVO series specifically targets applications where board space is limited but higher capacity than standard SRAM is needed. It serves as a drop-in replacement for some parallel PSRAMs in terms of software compatibility.
