Datasheet Serial EEPROM Series Standard EEPROM WLCSP EEPROM BU9880GUL-W (64Kbit) General Description 2 BU9880GUL-W is a serial EEPROM of I C BUS interface method. Features Package W(Typ.) x D(Typ.) x H(Max.) 2 Completely conforming to the world standard I C 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 VCSP50L1 At write operation (5.0V) : 0.5mA (Typ.) 1.98mm x 1.59mm x 0.55mm At read operation (5.0V) : 0.2mA (Typ.) At standby operation (5.0V) : 0.1A (Typ.) Write mistake prevention function Write (write protect) function added 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 Page Write Product number Number of pages BU9880GUL-W 32Byte Absolute Maximum Ratings (Ta=25) Parameter symbol Ratings Unit Remarks Impressed voltage V -0.3 to 6.5 V CC Permissible dissipation Pd 220 mW When using at Ta=25or higher, 2.2mW to be reduced per 1 Storage temperature range Tstg -65 to 125 Action temperature range Topr -40 to 85 Terminal voltage -0.3 to V +1.0 V The Max value of Terminal Voltage is not over 6.5V.
