Serial EEPROM Series Standard EEPROM
I2C BUS EEPROM (2-Wire)
BR24G32-3A
General Description BR24G32-3A is a 32Kbit serial EEPROM of I2C BUS Interface Method
Features
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 1.6V to 5.5V Single Power Source Operation most
suitable for battery use 1MHz action is possible(1.7V to 5.5V) Up to 32 Byte in Page Write Mode Bit format 4K x 8bit Self-timed Programming Cycle Low Current Consumption Prevention of Write Mistake
WP (Write Protect) Function added Prevention of Write Mistake at Low Voltage 1 million write cycles 40 years data retention Noise filter built in SCL / SDA terminal Initial delivery state FFh

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the
absolute maximum ratings.
