24C02C is a serial E2PROM storage device based on I2C-BUS, following the two-wire protocol. Because of its convenient connection, small size, and no loss of data when power is off, it has been widely used in instrumentation and industrial automation control. 24C02C has a standard two-wire serial interface. It is a single power supply with an operating voltage range of 4.5V to 5.5V. It can cascade up to eight devices and has a 16-byte page write buffer.
