High Reliability Serial EEPROMs High Reliability Series EEPROMs Microwire BUS BR93L-W Series, BR93A-WM Series, BR93H-WC Series No.11001EGT03 ROHM s series of serial EEPROMs represent the highest level of reliability on the market. A double cell structure provides a failsafe method of data reliability, while a double reset function prevents data miswriting. In addition, gold pads and gold wires are used for internal connections, pushing the boundaries of reliability to the limit. BR93L-W Series are assort 1Kbit16Kbit. BR93A-WM Series are possible to operate at 105 and are assorted with 1K16Kbit. BR93H-WC Series are possible to operate at 125, are assorted with 2K16Kbit.
