This part is now listed as Obsolete by the manufacturer. ## Supply, temperature, and package — the board-fit constraints Operates from a 3.135 V to 3.6 V core supply — a 3.3 V nominal rail with +/-5 % tolerance covers the range without an external regulator. The commercial temperature grade (0 °C to 70 °C) limits deployment to indoor, temperature-controlled equipment; no industrial or automotive extension is offered on this variant. The 165-ball LBGA package (15 x 17 mm body, 1.0 mm ball pitch per the FBGA-165 footprint) demands a controlled impedance PCB stack-up. The 2M x 36 parallel interface routes 36 data lines plus address and control — the trace-length matching budget on the DQ bus is tight at 133 MHz. The Tray packaging means the parts arrive in anti-static trays, not tape-and-reel; plan for manual or tray-fed pick-and-place. ## Sourcing an obsolete synchronous SRAM — what to expect The CY7C1471BV33-133BZXC is officially Obsolete. The only sourcing channel is the independent surplus and broker market, where lots are verified for authenticity and date-code freshness before quotation. Availability and pricing are lot-specific — confirmed at RFQ time against the required quantity. For a design still requiring this exact 72 Mbit NoBL™ part, the 165-FBGA footprint and 3.3 V supply are non-negotiable. No pin-compatible direct replacement from Infineon or a second source is documented — any alternative would require a board spin or an adapter.","metaTitle":"Infineon CY7C1471BV33-133BZXC SRAM, 72Mbit, 133 MHz","metaDescription":"Infineon CY7C1471BV33-133BZXC NoBL™ synchronous SRAM, 72Mbit (2M x 36), 133 MHz clock, 6.5 ns access time.","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":"6.5 ns","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","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":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$142.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/628924c755bdff75b315179b2f6927ff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1471BV33-133BZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the memory organization and interface of CY7C1471BV33-133BZXC?","answer":"It is a 72 Mbit synchronous SRAM organized 2M x 36, with a parallel interface clocked at 133 MHz (6.5 ns access time).
