Datasheet
Serial EEPROM Series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24Lxxx-W Series
(1K 2K 4K 8K 16K 32K 64K)
●General Description
BR24Lxxx-W series 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
1.8V to 5.5V *1 single power source action most
suitable for battery use
Page write mode useful for initial value write at
factory shipment
Highly reliable connection by Au pad and Au wire
Auto erase and auto end function at data write
Low current consumption
¾ At write operation (5V)
: 1.2mA (Typ.) *2
¾ At read operation (5V)
: 0.2mA (Typ.)
¾ At standby operation (5V) : 0.1μA (Typ.)
Write mistake prevention function
¾ Write (write protect) function added
Write mistake prevention function at low voltage
Data rewrite up to 1,000,000 times
Data kept for 40 years
Noise filter built in SCL / SDA terminal
Shipment data all address FFh
