High Reliability Series Serial EEPROM Series

WL-CSP EEPROM family

I2C BUS

BU9889GUL-W

●Description

BU9889GUL-W is a serial EEPROM of I

●Features

1) Completely conforming to the world standard I

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
