Datasheet
Serial EEPROM Series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24G256-3
General Description
BR24G256-3 is a 256Kbit serial EEPROM of I2C BUS Interface Method
Features

FAST MODE 400kHz operation
Up to 64 Byte in Page Write Mode
Bit Format 32K x 8
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
