The clock frequency is derived from an onboard 32.768KHz oscillator. RTC3 click communicates with the target board microcontroller through mikroBUS&trade; I2C lines: SCL, SDA. In addition, the INT pin serves as a configurable interrupt output.

The bq32000 features an automatic backup supply with integrated trickle charger. The backup supply can be implemented using a capacitor or non-rechargeable battery. The bq32000 has a programmable calibration adjustment from &ndash;63 ppm to 126 ppm. The bq32000 registers include an OF (oscillator fail) flag indicating the status of the RTC oscillator, as well as a STOP bit that allows the host processor to disable the oscillator.<br /><br /><strong>Applications:</strong><br /> <p>Board is ideal for applications which require real-time clocks, calendars and programmed alarms.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>BQ32000 RTC IC from Texas Instruments</li> <li>Integrated trickle charge circuit</li> <li>Communicates with target MCU through I2C</li> <li>Uses 3.3V power supply only</li> <li>Automatic switchover to backup power supply</li> <li>Ready-to-use examples save development time</li> <li>Supported in all MikroElektronika compilers</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Click Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.ti.com/lit/ds/symlink/bq32000.pdf" target="_blank">BQ32000 -

The clock frequency is derived from an onboard 32.768KHz oscillator. RTC3 click communicates with the target board microcontroller through mikroBUS&trade; 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. <br /><br />mikroBUS&trade; is specially designed pinout standard with SPI, I2C, Analog, UART, Interrupt, PWM, Reset and Power supply pins.<br /><br />The bq32000 device is a compatible replacement for industry standard real-time clocks. The bq32000 features an automatic backup supply with integrated trickle charger. The backup supply can be implemented using a capacitor or non-rechargeable battery. The bq32000 has a programmable calibration adjustment from &ndash;63 ppm to 126 ppm. The bq32000 registers include an OF (oscillator fail) flag indicating the status of the RTC oscillator, as well as a STOP bit that allows the host processor to disable the oscillator.<br /><br /><strong>Applications:</strong><br /> <p>Board is ideal for applications which require real-time clocks, calendars and programmed alarms.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>BQ32000 RTC IC from Texas Instruments</li> <li>Integrated trickle charge circuit</li> <li>Communicates with target MCU through I2C</li> <li>Uses 3.3V power supply only</li> <li>Automatic switchover to backup power supply</li> <li>Ready-to-use examples save development time</li> <li>Supported in all MikroElektronika compilers</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Click Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.ti.com/lit/ds/symlink/bq32000.pdf" target="_blank">BQ32000 - a real time clock with an integrated trickle charge circuit (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Product Brief/Fact sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.mikroe.com/downloads/get/1737/mikrobus-standard-specification-v200.pdf" target="_blank">mikrobus Specification (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.mikroe.com/downloads/get/2257/rtc-3-click-manual-v100.pdf" target="_blank">RTC3 Click (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Sample Code</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-code"></i> <a href="http://libstock.mikroe.com/projects/view/1678/rtc-i2c-library" target="_blank">RTC3 click Examples (html)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: real time clock, mikroelektronika, BQ32000, mcu, daughter_addon_boards, development_platforms_kits</div>
