Datasheet
Serial EEPROM Series Automotive EEPROM
105℃ Operation I2C BUS EEPROM (2-Wire)
BR24Axxx-WM
(1K 2K 4K 8K 16K 32K 64K)
●General Description
BR24Axxx-WM is a serial EEPROM of I2C BUS interface method.
●Features
Completely conforming to the world standard I2C BUS.
All controls available by 2 ports of serial clock
(SCL) and serial data (SDA)
Wide temperature range -40℃ to +105℃
Other devices than EEPROM can be connected to
the same port, saving microcontroller port
2.5V to 5.5V single power source operation most
suitable for battery use
Page write mode useful for initial value write at
factory shipment
Auto erase and auto end function at data rewrite
Low current consumption
¾ At write operation (5V)
: 1.2mA (Typ.) *1
¾ At read operation (5V)
: 0.2mA (Typ.)
¾ At standby condition (5V) : 0.1μA (Typ.)
Write mistake prevention function
¾ Write (write protect) function added
¾ Write mistake prevention function at low voltage
Data rewrite up to 1,000,000 times(Ta≦25℃）
Data kept for 40 years(Ta≦25℃）
Noise filter built in SCL / SDA terminal
Shipment data all address FFh
*1 BR24A32-WM, BR24A64-WM : 1.5mA
