What this 4.5Mbit synchronous SRAM does
The CY7C1347G-166AXC is a 4.5 Mbit synchronous SRAM organized as 128K words by 36 bits. It runs on a 166 MHz clock with a 3.5 ns access time, meaning the pipeline delivers one 36-bit word per clock cycle after the initial latency — a fit for high-throughput data buffers, cache tag stores, or network packet memory where deterministic read latency matters.
Infineon has designated the CY7C1347G-166AXC as Last Buy. This is the final procurement window before the part is discontinued — no further production runs are planned. Any remaining inventory is what is already manufactured and sitting in distribution or surplus channels. For a BOM that depends on this exact order code, the decision is time-sensitive: secure the lifetime buy quantity now, or plan a board spin to a pin-compatible or functionally equivalent SRAM.

Because this is a Last Buy part, the primary supply channel is independent distribution and surplus inventory. No stock-holding claim is made here; the part is quoted to order. For volume requirements or a last-time-buy quantity, submit an RFQ with your target quantity and target date.
