RTC
The RTC has an I2C Bus (2-wire SerialInterface) and offers temperature compensated time. The STC-Smart Temperature Compensation is calibrated in the factory and leads to a very high time-accuracy.

EEPROM
The Microchip Technology Inc. 24xx64 is a 64 Kbit Electrically Erasable PROM. The device is organized as a single block of 8K x 8-bit memory with a 2-wire serial interface. Lowvoltage design permits operation down to 1.7V, with standby and active currents of only 1 μA and 3 mA, respectively. It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24xx64 also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 512 Kbits address space.

Low Dropout Linear Regulator
The low-dropout (LDO) provides an easy-to-use robust power management solution for a wide variety of applications. User programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well- suited for powering many different types of Monitoring or Provides a Sequencing Signal processors and ASICs. The enable input and power for Other Supplies good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that meets the sequencing Voltage Startup requirements of FPGAs, DSPs, and other applications with special start-up requirements.
