These devices conform to all specifications in the I2C™ 2-wire protocol and are designed to minimize device pin count, and simplify PC board layout requirements. The upper half of the memory of the 24C03 can be disabled (Write Protected) by connecting the WP pin to VCC. This section of memory then becomes unalterable unless WP is switched to VSS. This communications protocol uses CLOCK (SCL) and DATA I/O (SDA) lines to synchronously clock data between the master (for example a microprocessor) and the slave EEPROM device(s). In addition, this bus structure allows for a maximum of 16K of EEPROM memory. This is supported by the Fairchild family in 2K, 4K, 8K, and 16K devices, allowing the user to configure the memory as the application requires with any combination of EEPROMs (not to exceed 16K). For devices with densities greater than 16K, a different protocol is used. Refer to 32K or higher densities for additional details. Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption.
