Datasheet
Serial EEPROM series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24Sxxx-W
(8K 16K 32K 64K 128K 256K)
General Description
BR24Sxxx-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
„ 1.7V to 5.5V single power source action most suitable
for battery use
„ FAST MODE 400kHz at 1.7V to 5.5V
„ 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 rewrite
„ Low current consumption
¾ At write operation (5V)
: 0.5mA (Typ.)
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
¾ 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
