It is part of the F-RAM™ family, which combines the fast write speed and high endurance of SRAM with the non-volatility of Flash or EEPROM — no battery backup required. The 2Mbit density (256K x 8) with SPI interface is a common footprint for code storage, configuration parameters, or small data logs. The 40 MHz clock frequency supports fast read/write cycles — FRAM writes at bus speed without the write-cycle delays of EEPROM, so no polling or page-write overhead. Supply voltage spans 2V to 3.6V, making it compatible with 3.3V and 2.5V logic systems; no level-shifter needed for a 3.3V MCU. The 8-WDFN Exposed Pad package (5x6 mm DFN) is a surface-mount footprint with a thermal pad, which aids heat dissipation in enclosed or warm environments. ## Lifecycle reality — this part is obsolete The FM25V20-DG carries an official lifecycle status of Obsolete. This means Cypress (now Infineon) has discontinued production, and no further factory orders are accepted. ## Sourcing and fit for new designs A buyer holding an existing BOM line for this part should qualify the supply route through independent distribution. For production continuity, an official replacement from the same F-RAM family exists — see the FAQ for the successor order code.","metaTitle":"FM25V20-DG 2Mbit FRAM SPI 40MHz - Obsolete, Sourced to Order","metaDescription":"Cypress FM25V20-DG 2Mbit FRAM, SPI interface, 40 MHz clock, 2V–3.6V, -40°C to 85°C, 8-DFN package.","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-WDFN Exposed Pad","Product Status":"Obsolete","Clock Frequency":"40 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2V ~ 3.6V","Base Product Number":"FM25V20","Memory Organization":"256K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-DFN (5x6)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is FM25V20-DG compatible with 3.3V systems?","answer":"Yes, the FM25V20-DG operates from 2V to 3.6V, so it is directly compatible with 3.3V logic without level shifting."},{"question":"Does FM25V20-DG support SPI mode 0?","answer":"The FM25V20-DG uses a standard SPI interface.
