The -40°C to +105°C ambient range and AEC-Q100 qualification mean this part is specified for under-hood automotive modules and industrial enclosures where the junction temperature climbs above 85°C. Supplied in Tape & Reel for automated pick-and-place; Cut Tape is also available for prototype or low-volume builds.","metaTitle":"ROHM BR93A66RFVM-WMTR EEPROM, 4Kbit, 2 MHz, 8-MSOP","metaDescription":"ROHM BR93A66RFVM-WMTR automotive EEPROM, 4Kbit, Microwire interface, 2 MHz clock, 2.5-5.5V, -40 to +105°C, AEC-Q100.
