Memory IC Procurement Notes

Verify the specific package variant, as BGGI8 denotes a 119-PBGA configuration. Confirm RoHS compliance status, as this specific part number may not meet current environmental regulations. Check for end-of-life notifications or product change notices affecting substrate or labeling. Ensure availability through authorized distributors due to potential discontinuation status.

Memory IC Selection Notes

Select this component when a 128K x 36 organization is required for synchronous memory applications. The 166 MHz speed grade suits designs needing 3.5 ns access latency. Consider the 119-PBGA footprint for board space constraints. Verify power supply requirements align with the 3.3V nominal specification range.

Memory IC Part Context

This part belongs to the 71V3556 family of synchronous SRAMs. It shares architectural similarities with other variants like the 71V3556SA166BQGI8 but differs in package type. The family targets high-density memory needs in networking and industrial sectors. Variants often share core specifications while differing in pin counts or thermal ratings.

Memory IC Replacement Considerations

The IDT71V3556S166BQG8 is listed as a similar alternative, though it uses a 165-CABGA package. Verify pin compatibility and physical dimensions before substitution. Other family members may offer different speed grades or packaging options.
