Description
BR24L
-W series is a serial EEPROM of I
2
C BUS interface method.
Features
Completely conforming to the world standard I
2
C BUS. All controls available by 2 ports of serial clock (SCL) and serial data (SDA)
Other devices than EEPROM can be connected to the same port, saving microcontroller port
