This part targets networking equipment, base stations, and DSP systems where a 36-bit wide data bus matches the processor or ASIC interface without external muxing. ## Bus timing margin at 133 MHz At 133 MHz the clock period is 7.5 ns, and the 6.5 ns access time leaves roughly 1 ns of setup margin before the next clock edge. That is tight — the board-level trace delay and clock skew need careful budgeting. The synchronous SDR pipeline eliminates the dead cycles of asynchronous SRAM on back-to-back reads, which matters for cache-line fills or packet buffer access patterns. It suits indoor telecom racks, lab instrumentation, and office-environment equipment. Not rated for outdoor, automotive, or extended industrial use — if the ambient can push past 70°C, look at the industrial-grade sibling in the same family. Listed as Active in the product lifecycle, so there is no imminent last-time-buy or end-of-life notice. The CY7C1361C-133AXCT is the Tape & Reel variant of the base CY7C1361C part; the tray-pack version (CY7C1361C-133AXC) shares identical silicon and timing.","metaTitle":"Infineon CY7C1361C-133AXCT 9Mbit SRAM, 133 MHz, 6.5 ns","metaDescription":"Infineon CY7C1361C-133AXCT synchronous SDR SRAM, 9Mbit (256K x 36), 133 MHz clock, 6.5 ns access, 3.3V, 100-TQFP.

All I/O are 3.3V-tolerant and interface directly with 3.3V logic families without level shifters."},{"question":"What is the difference between CY7C1361C and CY7C1361?","answer":"The CY7C1361C is the later revision with a 133 MHz clock rating and 6.5 ns access time, while the original CY7C1361 typically ran at lower speeds (100 MHz / 7.5 ns). The C-revision also incorporates process improvements for lower power. Both are 256K x 36 synchronous SRAM in the same 100-pin TQFP footprint, so the C variant is a drop-in speed upgrade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1361C-133AXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1361C-133AXCT when reusing this data.
