I²C BUS
BU9897GUL-W
●Description
BU9897GUL-W is a serial EEPROM of I²C BUS interface method.
Memory density is 128Kbit (16,384×8bit) , compact package VCSP50L2.
●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 ~ 5.5V single power source action most suitable for battery use.
4) FAST MODE 400kHz at 1.7 ~ 5.5V
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 (5.0V) : 0.5mA (Typ.)
At read operation (5.0V) : 0.2mA (Typ.)
At standby operation (5.0V) : 0.1µA (Typ.)
8) Write mistake prevention function
Write (write protect) function added
Write mistake prevention function at low voltage
9) Data rewrite up to 1,000,000 times
10) Data kept for 40 years
11) Noise filter built in SCL / SDA terminal
12) Shipment data all address FFh
