Supply voltage range is 3.135V to 3.6V – a tight 3.3V ±5% rail. If your board already runs 3.3V, this part drops in without a separate regulator; if the rail droops below 3.135V during transient, the SRAM may lose data integrity. Infineon lists this part as Obsolete. Confirm the exact package (100-TQFP 14x20 mm) and timing before selecting an alternative. ## Sourcing posture – quoted to order per RFQ Because this part is obsolete, it is not stocked on the shelf. We source it through our network of qualified distributors and surplus channels against your BOM quantity. Submit an RFQ with your target volume and date-code window, and we will return a firm offer.","metaTitle":"CY7C1371D-133AXCT 18Mbit SRAM – Obsolete, Sourcing Info","metaDescription":"Infineon CY7C1371D-133AXCT NoBL™ 18Mbit synchronous SRAM, 512K x 36, 133 MHz, 6.5 ns access, 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":"18Mbit","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":"CY7C1371","Memory Organization":"512K 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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How can I order CY7C1371D-133AXCT or check availability?","answer":"This part is obsolete, so it is not held available via RFQ confirmation.
