Real Time Clock Modules (RTC Module)

The RTC Module of EPSON can support SPI or I2C interface, and can completely replace the combination of RTC IC and 32kHz Crystal. And also the function of RTC Module is very complete. In addition to basic timing, you can also use Alarm, Event and Interrupt etc. functions as additional GPIOs. The RTC Module of EPSON even built-in the temperature compensating and power switching functions. The temperature compensating function can ensure the timing precision in the variety of temperature. The power switching function can be said that it is convenient and trouble-free to assist guests in designing RTC circuits without having to design additional power switching circuits.
