BU9847GUL-W_10 Datasheet, PDF (1/19 Pages) Rohm – WL-CSP EEPROM family I2C BUS

High Reliability Series Serial EEPROMs
WL-CSP EEPROM family
I²C BUS
BU9847GUL-W
No.10001EAT14
●Description
BU9847GUL-W series is a serial EEPROM of I²C BUS interface method. 1.7V single power source action and actions
available at 400kHz.
●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) Actions available at 400kHz clock (1.7V～5.5V)
4) 1.7～5.5V single power source action most suitable for battery use.
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 action (5V) : 1.2mA (Typ.)
At read action (5V) : 0.2mA (Typ.)
At standby action (5V) : 0.1μA (Typ.)
8) Write mistake prevention function
Write (write protect) function added.
●Page write
Write mistake prevention function at low voltage.
9) Data rewrite up to 1,000,000times.
Number of pages
16Byte
10) Data kept for 40 years.
11) Noise filter built in SCL / SDA terminal
