General Description

BR24Axxx-WM is a serial EEPROM of I2C BUS interface method.

Features

■ Completely conforming to the world standard I2C BUS.

All controls available by 2 ports of serial clock

(SCL) and serial data (SDA)

■ Wide temperature range -40℃ to +105℃

■ Other devices than EEPROM can be connected to

the same port, saving microcontroller port

■ 2.5V to 5.5V single power source operation 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 operation (5V) : 1.2mA (Typ.) *1

? At read operation (5V) : 0.2mA (Typ.)

? At standby condition (5V) : 0.1μA (Typ.)

■ Write mistake prevention function

? Write (write protect) function added

? Write mistake prevention function at low voltage

■ Data rewrite up to 1,000,000 times(Ta≦25℃）

■ Data kept for 40 years(Ta≦25℃）

■ Noise filter built in SCL / SDA terminal

■ Shipment data all address FFh

*1 BR24A32-WM, BR24A64-WM : 1.5mA
