It stores configuration parameters, calibration data, or event logs where non-volatility and fast writes matter, such as industrial controllers, metering, and point-of-sale terminals. At 40 MHz clock, a 64K x 8 array reads or writes at roughly 5 MB/s sustained. That clears a 512-bit configuration block in under 13 µs — no page-erase wait, no busy-poll. For data-logging applications, the FRAM can capture sensor bursts at microsecond intervals without dropping samples. Supply range 2V to 3.6V covers both 3.3V and 2.5V rails; at 2V the SPI interface still meets the 40 MHz timing with appropriate drive strength. No external regulator needed when running from a 3.0V coin cell for backup. 8-SOIC (3.90 mm width) — standard footprint, no thermal pad to route. The Tube shipment option suits bench prototyping and low-volume production; for reels the FM25V05-GTR variant is the tape-and-reel version. For dual-sourcing, the FM25VN10-G doubles the density to 1Mbit in the same 8-SOIC footprint and SPI protocol — parametric match except frame size.","metaTitle":"Cypress FM25V05-G F-RAM 512Kbit SPI 40MHz 8-SOIC","metaDescription":"Cypress FM25V05-G 512Kbit FRAM, SPI interface at 40 MHz, 2V-3.6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"F-RAM™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"F-RAM™","Package":"Tube","Technology":"FRAM (Ferroelectric RAM)","Memory Size":"512Kbit","Memory Type":"Non-Volatile","Memory Format":"FRAM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","Clock Frequency":"40 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2V ~ 3.6V","Base Product Number":"FM25V05","Memory Organization":"64K 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":"$12.9800","priceTiers":[{"qty":1,"price":"$12.98000","currency":"USD"},{"qty":10,"price":"$12.01100","currency":"USD"},{"qty":25,"price":"$11.84760","currency":"USD"},{"qty":50,"price":"$11.69880","currency":"USD"},{"qty":100,"price":"$10.25240","currency":"USD"},{"qty":250,"price":"$9.81284","currency":"USD"},{"qty":500,"price":"$9.74902","currency":"USD"},{"qty":1000,"price":"$9.08964","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d68b50b080c80a0e1f5a77f81e7f2c62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/FM25V05-G/alternatives.json"},"ai":{"faq":[{"question":"Is FM25V05-G compatible with 3.3V systems?","answer":"Yes, the supply range of 2V to 3.6V includes 3.3V directly.
