MIKROE RTC 6 Click

RTC6 Click carries Microchip’s MCP79410 Real-Time Clock/Calendar IC with built-in 64 bytes of battery-backed SRAM an additional 1 Kbit of EEPROM. 64 bits of protected EEPROM requires an unlock sequence to be unlocked which makes it suitable for storing a unique ID or other critical information. RTC6 Click tracks hours minutes seconds days months years and weekdays with leap year compensation until the year 2399. The clock frequency is derived from an onboard 32.768KHz crystal oscillator. Backup power is supplied by a coin-cell Lithium battery. RTC6 communicates with the target board MCU through the mikroBUS I2C interface (SCL SDA) along with a multifunction pin (MFP in place of default mikroBUS INT pin). The multifunctional pin (MFP) can be configured as an alarm a square wave frequency output or a general purpose output. The board is designed to use either a 3.3V or a 5V power supply.
