This part targets high-throughput cache, FIFO, and network buffer applications where back-to-back transactions matter — the NoBL™ architecture lets the controller start a write on the cycle immediately following a read without an idle clock. Infineon lists the CY7C1356CV25-166AXCT as Obsolete. No official successor part number appears in the lifecycle record. For a BOM line that still calls out this exact order code, supply now runs through independent distribution — new-old-stock or surplus inventory. ## 2.5 V supply, 100-TQFP — fit check for existing boards The 2.375 V to 2.625 V supply range means this part runs on a 2.5 V rail, not the 3.3 V or 1.8 V common in newer SRAMs. The 100-TQFP (14x20) package is a surface-mount footprint with 0.5 mm pitch — verify that the board's existing decoupling and signal routing match the pinout of the NoBL™ synchronous interface.","metaTitle":"CY7C1356CV25-166AXCT Infineon 9Mbit SRAM, 3.5 ns, 166 MHz","metaDescription":"CY7C1356CV25-166AXCT Infineon NoBL™ synchronous SRAM, 9Mbit (512K x 18), 3.5 ns access time, 166 MHz clock, 2.375V-2.625V supply, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","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":"Obsolete","Clock Frequency":"166 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.375V ~ 2.625V","Base Product Number":"CY7C1356","Memory Organization":"512K x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a7ef9613cd534ef644419074685578e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1356CV25-166AXCT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1356CV25-166AXCT?","answer":"This part is obsolete and sourced through independent distribution.
