Mikroelektronika MIKROE-1839 BQ32000 RTC-3 Click Board Real Time Clock

Technical description of the product (MIKROE-1839):

MIKROE-1839 BQ32000. Clock and calendar IC, 32.768KHz oscillator on board, I2C, 3.3V. RTC3 click carries BQ32000, a real time clock with an integrated trickle charge circuit for automatic switchover to a backup power supply (the circuit maintains the backup charge with an onboard super capacitor). The clock frequency is derived from an onboard 32.768KHz oscillator. RTC3 click communicates with the target board microcontroller through mikroBUS I2C lines: SCL, SDA. In addition, the INT pin serves as a configurable interrupt output. The board is designed to use a 3.3V power supply only. Type: RTC. Applications: Board is ideal for applications which require real-time clocks, calendars and programmed alarms. On-board modules: BQ32000 RTC IC from Texas Instruments. Key Features: Integrated trickle charge circuit. Communicates with target MCU through I2C. Key Benefits: Automatic switchover to backup power supply. Interface: GPIO, I2C. Input Voltage: 3.3V. Compatibility: mikroBUS. Click board size: S (28.6 x 25.4 mm).
