It uses an I²C serial interface running at up to 3.4 MHz and offers a 130 ns access time. FRAM combines non-volatile storage with SRAM-like read/write speed and endurance — no battery backup, no wear-leveling needed. This part is meant for industrial data logging, metering, and configuration storage where the system writes frequently and needs data retention without a battery. ## 130 ns access — timing margin on the I²C bus At 3.4 MHz (the high-speed I²C mode), the bit time is about 294 ns, so the FRAM has roughly half a bit period to respond. That is tight but within spec — the part is designed for this speed. If your master runs at 400 kHz standard mode, the margin is generous and the part works without any wait-state insertion. The supply range is 2.0 V to 3.6 V, which covers both 3.3 V and 2.5 V rails. At 3.3 V the I²C bus levels are compatible with standard 3.3 V logic — no level shifter needed if the master is also 3.3 V. At 2.5 V the bus voltage is lower, so check the master's VIL/VIH thresholds. That means Cypress (now Infineon) no longer produces it, and the only supply channel is the surplus / independent distribution market. ## Replacement options — what fits the socket If you need a drop-in replacement in the same 8-pin SOIC footprint with the same I²C interface, the closest functional sibling is the FM24V02A-G (256 Kbit, same 130 ns access, same 3.4 MHz I²C, same supply range and temperature grade). It is a lower-density part — 256 Kbit instead of 1 Mbit — so it only fits if your firmware fits in 32K x 8.","metaTitle":"FM24VN10-G F-RAM 1Mbit I2C FRAM, 130 ns, 8-SOIC","metaDescription":"Cypress FM24VN10-G 1Mbit FRAM, I2C 3.4 MHz, 130 ns access, 2V-3.6V, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"F-RAM™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"F-RAM™","Package":"Tube","Technology":"FRAM (Ferroelectric RAM)","Access Time":"130 ns","Memory Size":"1Mbit","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":"3.4 MHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2V ~ 3.6V","Base Product Number":"FM24VN10","Memory Organization":"128K 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":"$11.9400","priceTiers":[{"qty":1,"price":"$11.94000","currency":"USD"},{"qty":10,"price":"$11.06000","currency":"USD"},{"qty":25,"price":"$10.80880","currency":"USD"},{"qty":50,"price":"$10.75080","currency":"USD"},{"qty":100,"price":"$9.46400","currency":"USD"},{"qty":250,"price":"$8.99432","currency":"USD"},{"qty":500,"price":"$8.90424","currency":"USD"},{"qty":1000,"price":"$8.60829","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3c234958037a25a98ecea8529b979300.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/FM24VN10-G/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy FM24VN10-G available via RFQ confirmation?","answer":"This part is obsolete and not available through the original manufacturer.
