Datasheet
Serial EEPROM Series Standard EEPROM
WLCSP EEPROM
BU9847GUL-W (4Kbit)
General Description
BU9847GUL-W series is a serial EEPROM of I2C BUS interface method. 1.7V single power source action and actions
available at 400kHz.
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.
Actions available at 400kHz clock (1.7V to 5.5V)
1.7V to 5.5V single power source action most suitable for battery use.
Page write mode useful for initial value write at factory shipment.
Auto erase and auto end function at data rewrite.
Low current consumption
¾ At write action (5V) : 1.2mA (Typ.)
¾ At read action (5V) : 0.2mA (Typ.)
¾ At standby action (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 1,000,000times.
Data kept for 40 years.
Noise filter built in SCL / SDA terminal
Shipment data all address FFh.
