Datasheet
Serial EEPROM Series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24T256-W
General Description
BR24T256-W 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)
Other devices than EEPROM can be connected to
the same port, saving microcontroller port
1.6V to 5.5V Single Power Source Operation most
suitable for battery use
1.6V to 5.5V wide limit of operating voltage, possible
FAST MODE 400KHz operation
Page Write Mode useful for initial value write at
factory shipment
Self-timed Programming Cycle
Low Current Consumption
Prevention of Write Mistake
WP (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
