SPI GPP RTCC, 1KB EE, 64B SRAM, WDT, Event Detect, ID

The MCP795W10 SPI RTCC is highly integrated with memory and advanced features typically found in more expensive devices. Starting from a basic real-time clock, a digital trim for greater accuracy, a battery switch for emergency power supply, a time stamp for logging power outages and three memory types were added, including SRAM, EEPROM and a blank unique ID in a locked EEPROM section, which can also be ordered with a 48- or 64-bit MAC address. By adding a watchdog timer and two programmable event detect inputs, lower power consumption and greater system stability can be achieved by executing these functions and putting the MCU in sleep mode for extended periods of time.
