BU9847GUL-W_12 Datasheet, PDF (1/28 Pages) Rohm – WLCSP EEPROM

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.
