BQ32000 RTC IC from TI Integrated trickle-charge circuit Automatic switchover to backup power supply Communicates with target via I2C
RTC3 click carries the 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 on-board 0.22F supercapacitor. The clock frequency is derived from an on-board 32.768kHz oscillator.
This module is ideal for applications that require real-time clocks, calendars and programmed alarms. It counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year clock function and four-year calendar.
The board communicates with your target board's microcontroller through mikroBUS I2C lines (SCL, SDA). In addition, the INT pin serves as a configurable interrupt output.
This board is designed to use a 3.3V power supply only.
mikroBUS Click Boards Overview Click boards come with header pins that you must solder yourself. After that, they just plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. The sockets are found on Clicker boards, the Quail board, these mikromedia shields, and development systems from mikroElektronika (V7 systems and later).
You also can connect Click boards to many other popular platforms via these adapters:
- PC — Click USB Adapter (MIKROE-1433)
- Arduino — Arduino UNO click shield (MIKROE-1581)
- Raspberry Pi — Pi click shield (MIKROE-1512)
- BeagleBone Black — BeagleBone click shield (MIKROE-1596)
- STM32F3 Discovery — STM32F3 Discovery Shield (MIKROE-1447)
- STM32F4 Discovery — STM32F4 Discovery Shield (MIKROE-1481)
- Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad — Click BOOSTER PACK (MIKROE-1363)
- Freescale Freedom — FRDM-KL46Z click shield (MIKROE-1795), FRDM-K64F (MIKROE-1794)
In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
