It is qualified to AEC-Q100, which means it passes the stress tests required for automotive-grade components — the same qualification that lets it sit on a BOM for an ECU, a transmission controller, or a battery-management module without a separate PPAP waiver. The 8-SOP-J package (a 150-mil SOIC footprint) is a standard surface-mount form factor that reflows on the same profile as the rest of the board. ## Temperature grade — 105°C ceiling, not 85°C That 105°C upper limit is the difference between a part that lives in the passenger cabin and one that survives on an engine-mounted module or inside a headlamp assembly. The 5 ms write-cycle time per word or page is consistent across the full temperature range — no derating on the write timing at high temp. ## Active production — no LTB clock ticking For the procurement desk, that translates to a stable supply channel — no need to stockpile or scramble for a replacement mid-production run. ROHS3 compliant, so it clears the REACH and conflict-mineral declarations without a waiver.","metaTitle":"BR93A46RFJ-WME2 Automotive EEPROM, 1Kbit, 2 MHz Microwire","metaDescription":"ROHM BR93A46RFJ-WME2: AEC-Q100 qualified 1Kbit EEPROM, 2.5-5.5V supply, 2 MHz Microwire interface, -40 to 105°C.
