Serial EEPROM Series Standard EEPROM
WLCSP EEPROM
BU9880GUL-W (64Kbit)
General Description
BU9880GUL-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.
Auto erase and auto end function at data rewrite.
Low current consumption
¾ At write operation (5.0V)
¾ At read operation (5.0V)
: 0.5mA (Typ.)
: 0.2mA (Typ.)
¾ At standby operation (5.0V) : 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
