PLL Click Board

The PLL click is a frequency multiplier which uses the Phase-Locked Loop (PLL) techniques to provide a high-frequency clock output from a cheap, standard fundamental mode crystal oscillator. In addition to this, PLL click also offers a choice between nine different multiplication factors, programmed via states of the two input pins. The output range of the PLL click goes up to 160MHz.

RTC 2 Click Board

Introduce real time clock (RTC) functionality to the design using the RTC 2 Click Board. This add-on board features a low-power Maxim DS1307 serial real-time clock (RTC). It is a full binary-coded decimal (BCD) clock/calendar with programmable square-wave output signal. The board uses standard I2C interface for communication with the target host microcontroller. RTC2 click has a 3V/230mA lithium battery that works as a backup power supply. The timekeeping function continues even when the power supply status is OFF. Real-Time Clock (RTC) counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year clock function with four year calendar. It is designed to operate a 5V power supply only. In order to function to a 3.3V system, the user can check go for RTC click.

The RTC2 click is an ideal option who applications involving real-time clocks, calendars, and programmed alarms.

RTC 4 Click Board

MikroElektronika is here with a new RTC click! 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 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.

RTC Click Board

The RTC Click Board 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.
