The NoBL (No Bus Latency) pipeline lets the controller issue a new read address on every rising clock edge without inserting idle cycles between back-to-back reads — a key advantage for high-throughput packet buffers in networking gear or telecom line cards where every clock cycle counts. ## Supply and temperature — single 3.3V rail, commercial range Housed in a 100-LQFP (supplier device package 100-TQFP, 14x20 mm) — a standard fine-pitch quad flat pack that is rework-friendly with a hot-air station and does not require X-ray inspection like a BGA. ## Obsolete — sourcing through independent surplus channels Availability is limited to independent surplus and broker inventory — quantities are lot-specific and confirmed at RFQ. No pin-compatible drop-in replacement is documented; a board spin may be required if migrating to a different SRAM family.","metaTitle":"Infineon CY7C1471V33-133AXCT 72Mbit NoBL SRAM, 133 MHz","metaDescription":"Obsolete Infineon CY7C1471V33-133AXCT 72Mbit (2M x 36) synchronous SRAM, 133 MHz, 6.5 ns access, 3.3V, 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":"6.5 ns","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1471","Memory Organization":"2M 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":"$131.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/004045db93073bdba92daa481a7d2b36.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1471V33-133AXCT/alternatives.json"},"ai":{"faq":[{"question":"What is the memory organization and interface of CY7C1471V33-133AXCT?","answer":"It is a 72Mbit synchronous SRAM organized as 2M x 36, with a parallel memory interface.
