RTC Click Board, mikroE

The RTC Click is an accessory board designed to add time measuring functionality to the device. This click board has a PCF8583 serial real-time clock/calendar. The PCF8583 IC is a full binary-coded decimal (BCD) clock and calendar chip with 24- or 12-hour clock format with four-year calendar, based on a 2048-bit static CMOS RAM. For communication with the target board microcontroller, RTC Click uses the I2C interface. The board comes with an integrated 3V/230mA lithium battery that serves as a backup power supply. Even when the main power supply goes OFF, this backup power supply enables the device to function continuously. It is designed to use a 3.3V power supply, but can be used with 5V systems by soldering the PWR SEL SMD jumper to the 5V position.

RTC Click is an ideal choice for applications that require real-time clocks, calendars and programmed alarms.

IC/Module: PCF8583 Serial Real-Time Clock/Calendar

PCF8583 is a clock and calendar IC based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. It involves transferring addresses and data serially through the two-line bidirectional I2C-bus. The integrated 32.768 kHz oscillator circuit and the first 8 bytes of the RAM are used for the clock/calendar and counter functions. The next 8 bytes may be programmed as alarm registers or used as free RAM space. The remaining 240 bytes are free RAM locations.

Power Supply Selection

RTC Click is provided with a zero-ohm PWR SEL SMD jumper that enable user to choose a 3.3V or 5V power supply. By default, the jumper is soldered to the 3.3V position
