Wide-bus synchronous SRAM for pipeline-critical systems
The CY7C1354C-166AXCT is a 9 Mbit synchronous SRAM from Infineon's NoBL™ (No Bus Latency) series, organized 256K x 36 — a 36-bit-wide data path that suits networking packet buffers, switch fabrics, and DSP scratchpads where a single read/write cycle must move a full word or descriptor. Rated for 166 MHz operation with a 3.5 ns access time, the part eliminates the dead bus cycle between reads and writes that conventional pipelined SRAMs require, so the controller sees back-to-back transactions at the full clock rate.
Active lifecycle and commercial temperature envelope
It remains a current-production line item for new builds. Temperature range is 0°C to 70°C ambient, the commercial grade. This covers indoor telecom central offices, data-center switches, and test equipment; it does not extend to outdoor base stations or automotive engine bays.
Package and board-fit: 100-TQFP on tape
Shipped in Tape & Reel rather than tray, so it feeds directly into a pick-and-place machine without a media change.
