167 MHz synchronous SDR SRAM — the cache-line workhorse
It uses a single-data-rate (SDR) pipeline architecture — every rising clock edge latches address and control, and the data appears after the programmed latency. This part is designed for high-throughput buffering in networking equipment, base stations, and test instrumentation where deterministic read-write latency matters more than the burst efficiency of DDR SRAM.
At 167 MHz the clock period is about 6 ns, so this access time leaves roughly 2.6 ns for board trace delay, input setup, and output hold — a tight but manageable margin for a well-terminated bus on a typical FR4 PCB. Designs that push trace lengths beyond 4 inches or use multiple loads on the same data bus should budget a derating simulation.
Last Buy — plan the final order window
For production builds that depend on this exact density and speed grade, the procurement strategy is to secure lifetime-buy quantities through the authorized channel or, after the LTB window closes, source from independent distribution against an RFQ.
Package and footprint — 100-LQFP (14x20 mm)
The supplier device package is 100-TQFP (14x20), which is the same footprint — TQFP and LQFP are thermally and dimensionally interchangeable for this body size.
