That access time is the window from clock edge to data valid — at 166 MHz the cycle is 6 ns, so a 3.5 ns access leaves 2.5 ns of setup margin for the controller or FPGA. This part is designed for high-throughput cache, network buffer, or DSP scratchpad where the pipeline cannot stall for wait states. ## Last Buy — plan your final order That means Infineon has announced end-of-life and the final order window is closing. Once the last-time-buy date passes, the only supply channel will be surplus and broker inventory. If this SRAM is on your BOM, now is the time to commit to a lifetime buy or qualify a replacement. ## 166 MHz pipeline — matching the controller The 166 MHz clock frequency defines the maximum bus speed. This part uses a synchronous SDR (single data rate) interface — one data transfer per clock cycle. For a 36-bit wide bus running at 166 MHz, the raw bandwidth is about 747 MB/s. ## Commercial temperature — indoor use only It belongs in office equipment, telecom racks, or lab instrumentation — not in a motor drive, engine bay, or outdoor enclosure. The 100-TQFP (14x20 mm) package is surface-mount and requires standard reflow handling; MSL level should be confirmed from the latest Infineon packing label before bake decisions.","metaTitle":"Infineon CY7C1366C-166AXCT 9Mbit Sync SRAM, 166 MHz, 3.5 ns","metaDescription":"Infineon CY7C1366C-166AXCT synchronous SRAM, 9 Mbit (256K x 36), 166 MHz clock, 3.5 ns access time, 3.135-3.6 V, 100-TQFP, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, SDR","Access Time":"3.5 ns","Memory Size":"9Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Last Time Buy","Clock Frequency":"166 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1366","Memory Organization":"256K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.1489","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e803a233592551a93e12554c6ddd018.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1366C-166AXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1366C-166AXCT obsolete or in last buy status?","answer":"Yes, this part is in Last Buy status.
