The MCP795W11 SPI RTCC is highly integrated with memory and advanced features normally found in higher priced devices. By starting with a basic real-time clock, digital trimming was added for higher accuracy, a battery switchover for backup power, a timestamp to log power failures and three types of memory, which includes SRAM, EEPROM and a unique ID in a locked section of EEPROM that is preprogrammed with a 48-bit MAC Address that can also be ordered blank for the end user to program. By adding a watchdog timer and two programmable event detect inputs, lower power and more system robustness can be achieved by off-loading MCU functions and allowing it to sleep for longer periods of time.
