BR93L□□-W Series, BR93A□□-WM Series, BR93H□□-WC Series
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 1Kbit~16Kbit. BR93A□□-WM Series are possible to operate at 105℃ and are assorted
with 1K~16Kbit. BR93H□□-WC Series are possible to operate at 125℃, are assorted with 2K~16Kbit.
