Serial EEPROM Series Standard EEPROM
WLCSP EEPROM
BU9889GUL-W (8Kbit)
●General Description
BU9889GUL-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)
■ 1k words×8 bits architecture 8kbit serial EEPROM.
■ 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.
■ 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 100,000 times
■ Data kept for 40 years
■ Noise filter built in SCL / SDA terminal
■ Shipment data all address FFh
