RTC5 click carries MCP79510, a real-time clock/calendar with an SPI interface (mikroBUS MISO, MOSI, SCK and CS pins); along with a programmable interrupt for system output. The clock frequency is derived from an onboard 32.768KHz oscillator. For backup power, RTC5 click has a coin-cell Lithium polymer battery connector. The chip has 64-bytes of battery-backed SRAM and 1 kbit of EEPROM for storing data, along with 128 bits of protected space for storing a unique ID. The clock/calendar automatically compensates for leap years and months shorter than 31 days. The board is designed to use a 3.3V power supply only.
