FRAM is non-volatile and writes complete in a single bus cycle with no erase-before-write delay. ## 40 MHz SPI — bus timing and throughput The 40 MHz SPI clock supports sequential reads and writes at up to 40 Mbps. Unlike serial Flash, there is no page buffer or sector-erase latency — every byte write completes in the same bus cycle as a read. For a design that logs sensor data or stores configuration parameters in a tight loop, this eliminates the write-time jitter that Flash introduces. ## Obsolete — sourcing reality for FM25H20-G","metaTitle":"FM25H20-G 2Mbit SPI FRAM, 40 MHz, 8-SOIC","metaDescription":"FM25H20-G is a 2Mbit non-volatile FRAM with 40 MHz SPI interface in 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"F-RAM™","Package":"Tube","Technology":"FRAM (Ferroelectric RAM)","Memory Size":"2Mbit","Memory Type":"Non-Volatile","Memory Format":"FRAM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","Clock Frequency":"40 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"FM25H20","Memory Organization":"256K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.0400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b70f41dba86863d89d30f00f830e49be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/FM25H20-G/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of FM25H20-G?","answer":"FM25H20-G is a 2 Mbit non-volatile FRAM with an SPI interface running at 40 MHz, organised as 256 K × 8 bits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/FM25H20-G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/FM25H20-G when reusing this data.
