RTC 4 Click Board
MikroElektronika is here with a new RTC Click Board™! RTC 4 Click Board™ is a time measurement add-on board that incorporates DS2417 IC. The DS2417 is a real-time clock/calendar (RTC) with fully compatible 1-Wire MicroLAN interface. It also features a programmable interrupt output for system wakeup on a separate pin. It utilizes an on-chip oscillator that is connected to an external 32.768 kHz crystal. Being a 1-Wire device, it features a unique, factory-lasered 64-bit long ROM code that allows the user to use it in a MicroLAN network.
It uses a backup energy source that maintains a charge with an on-board coin cell 1F supercapacitor. The real time clock has an accuracy of +/- 2 minutes per month at 25°C. RTC4 Click Board™ communicates with the target board MCU either through MikroBUS AN or PWM pin (here, GPI01, GPIO0), plus the INT pin, depending on the position of the on-board jumper.
- Based on the DS2417 1-Wire Time Chip with Interrupt
- Communicates at 16.3 Kbits per second
- Fitted with a coin cell 1F supercapacitor
- Unique, factory-lasered and tested 64-bit registration number
- Operating voltage range: 2.5V to 5.5V
- Operating temperature range: -40
- Easy integration in mikroBUS form factor
- Can use either 3.3V or 5V power
- Supported by all MikroElektronika compilers
DS2417 is a time chip featuring a unique 64-bit lasered ROM and a real-time clock/calendar. It would make a great choice for any electronic appliance or embedded application using a microcontroller to add functions such as calendar, time and date stamp, and logbook. This compact, low-cost DS2417 package uses a 1-Wire interface for communication with the target board. It also has a programmable interrupt for system wakeup.
RTC4 Click includes a coin cell 1F supercapacitor that blends in with your design and enable the Click to do its work for a long time. On the Click Board™, the DS2417 IC is placed under the supercapacitor.
1-Wire Interface (Selectable Pins)
In RTC4 Click, DS2417 acts as a slave device and communicates with the master MCU through a 1-Wire bus. With its 64-bit registration number, RTC4 Click can function within a MicroLAN network, i.e, a network of 1-Wire devices that are all associated with a master device.
