Description
BU99901GUZ-W series is a serial EEPROM of I2C BUS interface method.

FEATUREs
1) Completely conforming to the world standard I2C BUS.
   All controls available by 2 ports of serial clock (SCL) and serial data (SDA)
2) Other devices than EEPROM can be connected to the same port, saving microcontroller port.
3) 1.7～ 3.6V single power source action most suitable for battery use.
4) FAST MODE 400kHz at 1.7～ 3.6V
5) Page write mode useful for initial value write at factory shipment.
6) Auto erase and auto end function at data rewrite.
7) Low current consumption
   At write operation (3.3V) : 0.6mA (Typ.)
   At read operation (3.6V) : 0.6mA (Typ.)
   At standby operation (3.6V) : 0.1µA (Typ.)
8) Write mistake prevention function
   Write (write protect) function added
   Write mistake prevention function at low voltage
9) Compact package
10) Data rewrite up to 100,000 times
11) Data kept for 40 years
12) Noise filter built in SCL / SDA terminal
13) Shipment data all address FFh
