High Reliability Series Serial EEPROMs

WL-CSP EEPROM family

I²C BUS

No.10001EAT18

BU9844GUL-W

●Description

BU9844GUL-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)

At read action (5V)

: 1.2mA (Typ.)

: 0.2mA (Typ.)

At standby action (5V) : 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 1,000,000times.

10) Data kept for 40 years.

11) Noise filter built in SCL / SDA terminal

12) Shipment data all address FFh.
