The Digilent PmodRTCC Peripheral Module is a Real-Time Clock/Calendar powered by the MCP79410. It is compatible with Digilent`s PIC32-based Cerebot development boards (TDGL008, TDGL009, TDGL010), and can be easily connected to any system using standard IDC connectors and cables. An I2C interface is used to communicate with the module. The PmodRTCC provides two available alarms, 128 bytes EEPROM and 64 bytes SRAM. The multi-function pin can be accessed via a two pin header.
The MCP79410 general purpose I2C™Compatible real-time clock/calendar (RTCC) is highly integrated with nonvolatile memory and advanced features normally found in higher priced devices. These features include a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a low-cost 32.768 kHz crystal or other clock source, time is tracked in either a 12-hour or 24-hour format with an AM/PM indicator and timing to the second, minute, hour, day of the week, day, month and year. As an interrupt or wakeup signal, a multifunction open drain output can be programmed as an Alarm Out or as a Clock Out that supports 4 selectable frequencies. In addition, non-volatile memory is included along with a Unique ID in a locked section of EEPROM that can be unlocked and programmed by the End User.
