I2C BUS
BU9889GUL-W
●Description
BU9889GUL-W 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) 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)
: 0.2mA (Typ.)
At standby operation (5V) : 0.1µA (Typ.)
9) Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
10) WLCSP6pin compact package
11) Data rewrite up to 100,000 times
12) Data kept for 40 years
13) Noise filter built in SCL / SDA terminal
14) Shipment data all address FFh
