Datasheet
Serial EEPROM Series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24G32-3
General Description
BR24G32-3 is a 32Kbit serial EEPROM of I2C BUS Interface Method
Features
Packages W(Typ) x D(Typ) x H(Max)
Completely conforming to the world standard I2C
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

FAST MODE 400kHz operation
Up to 32 Byte in Page Write Mode
Bit Format 4K x 8
Self-timed Programming Cycle
Low Current Consumption
Prevention of Write Mistake
Write (Write Protect) Function added
Prevention of Write Mistake at Low Voltage
More than 1 million write cycles
More than 40 years data retention
Noise filter built in SCL / SDA terminal
Initial delivery state FFh
