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
¾ Write (Write Protect) Function added
¾ 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
