The FM25V01-G is listed as obsolete. For a BOM that already specifies this part, the only sourcing path is through independent distribution — stock is limited to existing inventory held by brokers and surplus houses. Any new design should move to a current-production FRAM or a pin-compatible serial SRAM/EEPROM alternative. There is no factory lead time to rely on, so a firm order commitment is the only way to secure units. ## Sourcing the FM25V01-G through independent channels For buyers who need to fill an existing BOM line, the FM25V01-G is sourced through our independent distribution network. Each unit is verified against the original manufacturer's markings and tested for basic functionality before shipment. We do not hold a standing inventory of this obsolete part; each request is handled as a spot-market procurement with a confirmed quote before any order is placed.","metaTitle":"FM25V01-G 128Kbit FRAM, 40 MHz SPI, 8-SOIC","metaDescription":"FM25V01-G 128Kbit non-volatile FRAM, 40 MHz SPI, 2V–3.6V, 8-SOIC, -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":{"title":"FM25V01-G","Series":"F-RAM™","Package":"Tube","Technology":"FRAM (Ferroelectric RAM)","Memory Size":"128Kbit","Memory Type":"Non-Volatile","Memory Format":"FRAM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"40 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2V ~ 3.6V","Base Product Number":"FM25V01","Memory Organization":"16K x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e2aef2eb7585c28b836bc0189cbc77c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for FM25V01-G?","answer":"The evidence does not list an official successor from Ramtron (now Cypress/Infineon). For a pin-compatible replacement, look at current-production FRAM parts in the same 8-SOIC footprint with 128Kbit density and SPI interface, such as the Cypress FM25V01A-G (if still active) or the Infineon EXCELON series.
