The supply range spans 2.5V to 5.5V, so it runs on either a 3.3V or 5V automotive rail without an extra regulator. ## AEC-Q100 grade and what it buys you The AEC-Q100 stamp means this part passed the stress tests automotive modules need: extended temperature cycling, high-temperature operating life, and ESD robustness. For a sourcing decision, it removes the qualification risk — you can drop this into a production ECU BOM without running your own reliability campaign. The series is explicitly Automotive, AEC-Q100, so the qualification is on the datasheet, not inferred from the temp range alone. ## 10 MHz SPI and 4ms page write The 10 MHz SPI clock is fast enough to read calibration tables or fault logs without stalling the main microcontroller. Write cycle time is 4ms per word or page — typical for this density, and predictable enough to budget in a firmware state machine. The 4Kbit density (512 x 8) suits parameter storage: VIN, serial numbers, trim coefficients, and diagnostic trouble codes. It is not a code store; treat it as the non-volatile scratchpad for the ECU's configuration. ## Lifecycle and sourcing For procurement, this means no urgency to qualify an alternate — but as with any active part, confirming availability at quote time is standard practice. The part is RoHS3 compliant.","metaTitle":"BR25H040FVT-2CE2 EEPROM 4Kbit SPI 10MHz AEC-Q100 8-TSSOP","metaDescription":"ROHM BR25H040FVT-2CE2 automotive AEC-Q100 EEPROM, 4Kbit SPI 10MHz, 2.5-5.5V, -40 to 125°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Memory Size":"4Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"10 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2.5V ~ 5.5V","Memory Organization":"512 x 8","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-TSSOP-B","Write Cycle Time - Word, Page":"4ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.60000","currency":"USD"},{"qty":10,"price":"$0.54800","currency":"USD"},{"qty":25,"price":"$0.54160","currency":"USD"},{"qty":50,"price":"$0.53840","currency":"USD"},{"qty":100,"price":"$0.48140","currency":"USD"},{"qty":250,"price":"$0.47732","currency":"USD"},{"qty":500,"price":"$0.47026","currency":"USD"},{"qty":1000,"price":"$0.45344","currency":"USD"},{"qty":3000,"price":"$0.42685","currency":"USD"},{"qty":6000,"price":"$0.41301","currency":"USD"},{"qty":15000,"price":"$0.39944","currency":"USD"},{"qty":30000,"price":"$0.38400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/929bfcb71a382182b76b167b5cfd25ce.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BR25H040FVT-2CE2 AEC-Q100 qualified?","answer":"Yes, the BR25H040FVT-2CE2 is part of ROHM's Automotive series and carries AEC-Q100 qualification.
