●General
Description
2
BR24Lxxx-W series is a serial EEPROM of I C BUS interface method
●Features
2
Completely conforming to the world standard I 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
