The body width is the narrow SOIC variant (150 mil), so the PCB footprint matches standard 8-pin SOIC land patterns — no special pad geometry required.","metaTitle":"ROHM BR93H66RF-WCE2 EEPROM, 4Kbit, 1.25MHz, 8-SOP","metaDescription":"ROHM BR93H66RF-WCE2 4Kbit EEPROM, Microwire interface, 1.25 MHz clock, -40 to +125°C, AEC-Q100, 8-SOP.
