AEC-Q100 qualification places it in the Grade 1 temperature band (-40°C to +105°C ambient), meaning the die and package survive the under-hood thermal profile — a transmission controller seeing 95°C on a hot drivetrain still has margin before the silicon limits. ## Supply range, write timing, and package footprint The page write cycle completes in 5 ms typical, so a firmware update writing 64 bytes across 8 pages finishes in under 40 ms plus bus overhead. The footprint matches standard SOIC-8 land patterns — no board spin required if migrating from a generic 8-pin EEPROM. Supplied on Tape & Reel or Cut Tape for volume or prototype kitting. ## Active lifecycle and compliance status ROHS3 compliant, which covers the full ten-substance restriction plus the four phthalates, so the part clears EU and UKCA regulatory gates without an exemption review. Sourced through independent and franchised distribution channels.","metaTitle":"BR24A04FJ-WME2 ROHM 4Kbit I2C EEPROM, AEC-Q100, 8-SOP-J","metaDescription":"ROHM BR24A04FJ-WME2 automotive EEPROM, 4Kbit I2C 400 kHz, 2.5-5.5V, -40 to +105°C, AEC-Q100, 8-SOP-J.
