Rohm BU9847GUL-W series is a serial EEPROM of I C BUS interface method. 1.7V single power source action and actions available at 400kHz.
- 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.
- Actions available at 400kHz clock (1.7V~5.5V)
- 1.7~5.5V single power source action most suitable for battery use.
- Page write mode useful for initial value write at factory shipment.
- Auto erase and auto end function at data rewrite.
- Low current consumption: At write action (5V), 1.2mA (Typ.); At read action (5V), 0.2mA (Typ.); At standby action (5V) : 0.1μA (Typ.)
- Write mistake prevention function
- Page write
- Write (write protect) function added.
- Write mistake prevention function at low voltage.
- Number of pages 16Byte
- Data rewrite up to 1,000,000times.
- Data kept for 40 years.
- Noise filter built in SCL / SDA terminal
- Shipment data all address FFh.
