36 Mbit NoBL synchronous SRAM for high-throughput data paths
It clocks at 133 MHz with a 6.5 ns access time, allowing back-to-back read/write operations without dead cycles on the bus. The parallel memory interface and 3.135V to 3.6V supply make it a fit for high-performance networking, telecom, and data-acquisition systems that need fast, wide memory with predictable timing.
The 133 MHz clock rate and 6.5 ns access time define the timing closure window for the memory controller. At this speed, PCB trace length matching and signal-integrity on the data bus matter — the part expects clean clock and control edges. The NoBL architecture eliminates the turnaround dead cycle typical of conventional synchronous SRAM, so the bus stays utilized at full throughput during mixed read/write sequences.
For a BOM line, that removes the obsolescence risk during a new product introduction or a multi-year production run.
100-TQFP package — rework and layout considerations
The 100-TQFP (14x20 mm) is a fine-pitch surface-mount package with gull-wing leads. It reworks cleanly under hot air if you preheat the board — the leads are visible for inspection and touch-up. No exposed paddle on this package, so dissipation relies on the leadframe and board copper.
