Description
General part information
MCP795W10 Series
The MCP795W10 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 blank unique ID in a locked section of EEPROM that can also be ordered with a 48-bit or 64-bit MAC Address. Then by adding a watchdog timer and two programmable event detect inputs, lower power and more system robustness can be achieved by performing these functions and allowing the MCU to sleep for longer periods of time.
