Datasheet
Serial EEPROM Series Standard EEPROM
I²C BUS EEPROM (2-Wire)
BR24Gxxx-3A (128K 256K 1M)
General Description
BR24Gxxx-3A is a serial EEPROM of I²C BUS Interface Method
Features
Packages W(Typ) x D(Typ)x H(Max)
 All controls available by 2 ports of serial clock(SCL) and
serial data(SDA)
 Other devices than EEPROM can be connected to the
same port, saving microcontroller port
 1.7V to 5.5V Single Power Source Operation most
suitable for battery use
 1.7V to 5.5V wide limit of operating voltage, possible
1MHz operation
 Page Write Mode useful for initial value write at factory
shipment
 Self-timed Programming Cycle
 Low Current Consumption
 Prevention of Write Mistake
 Write (Write Protect) Function added
 Prevention of Write Mistake at Low Voltage
 More than 1 million write cycles
 More than 40 years data retention
 Noise filter built in SCL / SDA terminal
 Initial delivery state FFh
