The 167 MHz clock rate and 3.4 ns access time are the headline specs that determine whether this part can keep up with a high-speed ASIC, FPGA, or network processor. The NoBL architecture eliminates the dead cycle that conventional synchronous SRAMs insert when switching between read and write — every clock edge can be a valid transaction. For a 4M x 18 configuration, that means a peak bandwidth of roughly 3 Gbit/s on the data bus. The 3.4 ns access time gives the controller about one clock cycle of setup margin at 167 MHz, so board-level signal integrity matters: keep trace lengths matched and place the termination resistors close to the memory pins. ## Industrial temperature grade and 3.3V supply rail The 3.135V to 3.6V supply window means the part runs comfortably on a nominal 3.3V rail with ±5% tolerance — typical for most digital systems. The 100-TQFP package has a 0.5 mm pitch and a 14x20 mm body; the exposed pad is not present on this package variant, so all thermal dissipation goes through the leads. Decouple with a 0.1 µF ceramic per supply pin pair, placed as close to the package as the board allows.","metaTitle":"Cypress CY7C1472V33-167AXI NoBL SRAM, 72Mbit, 167 MHz","metaDescription":"Cypress CY7C1472V33-167AXI NoBL synchronous SRAM, 72Mbit (4M x 18), 167 MHz clock, 3.4 ns access, 3.3V supply, 100-TQFP, -40°C to 85°C.","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":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"3.4 ns","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1472","Memory Organization":"4M x 18","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$125.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/63555aa8b5a6d221e163fecee1a9e074.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1472V33-167AXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1472V33-167AXI obsolete?","answer":"Yes, the CY7C1472V33-167AXI carries an Obsolete lifecycle status.
