| Memory ICs I2C Bus compatible serial EEPROM BR24C08 / BR24C08F / BR24C08FV/ under BR24C16 / BR24C16F / BR24C16FV development *Features of operating power supply voltages (2.7V to 5.5V). * Wide range * * * * 2-wire serial interface. Auto erase and auto completion function when writing data. Page write mode function:16byte Low current consumption. - Operating (at 5V) : 2.0mA (typ.) - Standby (at 5V) : 1.0A (typ.) Write protect function. - Equipped with WP (write protect) function. - Writing disabled when power supply voltage is low. Compact DIP8, SOP8, and SSOPB8 packages. Highly reliable COMS processing. Rewriting possible up to 100,000 times. Data can be stored for ten years without corruption. Built-in noise filters at SCL and SDA pins. * * * * * * *Pin assignments VCC WP SCL SDA BR24C08 / F / FV BR24C16 / F / FV A0 A1 A2 GND 1 Memory ICs BR24C08 / BR24C08F / BR24C08FV / BR24C16 / BR24C16F / BR24C16FV *Overview BR24C08F, BR24C08FV, BR24C16, BR24C16F, and BR24C16FV are 2-wire (I C bus type) serial The BR24C08, 2 EEPROMs which are electrically programmable.
