BU9880GUL-W

Datasheet 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 ...
