It's part of ROHM's Automotive, AEC-Q100 series, which means it's qualified for the temperature and reliability demands of under-hood and chassis-domain electronics. Write-cycle time is 4 ms per word or page, which is typical for this density class and fast enough for parameter logging at the 10 MHz bus rate. ## 125°C operating ceiling — what it buys you A 125°C junction rating means the part can live in an engine control unit, a transmission controller, or a sensor module bolted to a hot manifold. If your BOM calls for an AEC-Q100-qualified non-volatile memory that holds calibration data through a thermal cycling test, this is the tier you're looking for. ## Package and footprint reality It comes in an 8-MSOP package (the 8-VSSOP / 8-MSOP 2.80 mm width variant) — surface-mount only, no through-hole option. The supplier device package is 8-MSOP, which is a fine-pitch SOP with about 0.65 mm lead pitch. That footprint is shared across several ROHM serial EEPROM densities, so a board layout for a 32Kbit part can often take this 64Kbit drop-in if the pinout matches. The shipping form is Tape & Reel or Cut Tape, so it feeds straight into a pick-and-place line. ## Lifecycle — no LTB scramble here For a procurement decision, that means you can qualify this into a production BOM without budgeting for an obsolescence-driven respin in the next few years. If the line ever does move to phase-out, ROHM typically issues a PCN with a multi-quarter LTB window, but right now there's nothing to watch for.","metaTitle":"ROHM BR25H640FVM-2ACTR 64Kbit SPI EEPROM, AEC-Q100, 10 MHz","metaDescription":"ROHM BR25H640FVM-2ACTR automotive 64Kbit SPI EEPROM, 10 MHz clock, 2.5V-5.5V, -40°C to 125°C, 8-MSOP.
