High Reliability Series Serial EEPROMs

WL-CSP EEPROM family

BU9880GUL-W

●

Description

BU9880GUL-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) 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) Compact package

10) Data rewrite up to 1,000,000 times

11) Data kept for 40 years

12) Noise filter built in SCL / SDA terminal

13) Shipment data all address FFh
