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
