High Reliability Series Serial EEPROM Series
WL-CSP EEPROM family I2C BUS
BU9889GUL-W
●Description 2 BU9889GUL-W is a serial EEPROM of I C BUS interface method. ●Features 2 1) Completely conforming to the world standard I C BUS. All controls available by 2 ports of serial clock (SCL) and serial data (SDA) 2) 1k words×8 bits architecture 8kbit serial EEPROM. 3) Other devices than EEPROM can be connected to the same port, saving microcontroller port. 4) 1.7~5.5V single power source action most suitable for battery use. 5) FAST MODE 400kHz at 1.7~5.5V 6) Page write mode useful for initial value write at factory shipment. 7) Auto erase and auto end function at data rewrite. 8) Low current consumption At write operation (5V) : 0.5mA (Typ.) At read operation (5V) : 0.
