No.09001EDT04
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. BR24L□□-W Series assort 1Kbit～64Kbit. BR24S□□□-W Series are possible to operate at high speed in low voltage and assort 8Kbit～256Kbit.

High Reliability Series EEPROMs I2C BUS
BR24L□□-W Series
●Description 2 BR24L□□-W series is a serial EEPROM of I C BUS interface method. ●Features 2 1) Completely conforming to the world standard I C BUS. All controls available by 2 ports of serial clock(SCL) and serial data(SDA) 2) Other devices than EEPROM can be connected to the same port, saving microcontroller port *1 3) 1.8V~5.5V single power source action most suitable for battery use 4) Page write mode useful for initial value write at factory shipment 5) Highly reliable connection by Au pad and Au wire 6) Auto erase and auto end function at data rewrite 7) Low current consumption *2 At write operation (5V) : 1.2mA (Typ.) At read operation (5V) : 0.2mA (Typ.) At standby operation (5V) : 0.1μA (Typ.) 8) Write mistake prevention function Write (write protect) function added 9) Write mistake prevention function at low voltage 10) SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J/VSON008X2030 compact package *3 11) Data rewrite up to 1,000,000 times 12) Data kept for 40 years 13) Noise filter built in SCL / SDA terminal 14) Shipment data all address FFh
