IDUINO ARD RTC DS1307 - Arduino - RTC - Real Time Clock, Tiny RTC Module, 24C3232K
11.19 EUR
"Real-time clocks (RTCs) are, as the name suggests, clock devices. The DS1307 real-time clock IC is an 8-pin device with an I2C interface, a low-power calendar with 56 bytes of battery-backed SRAM. The clock/calendar provides seconds, minutes, hours, day, date, month and year. The end date of each month is automatically adjusted, especially for months with less than 31 days.The main advantage of RTCs is that they have battery backup, which keeps the clock/calendar running even in the event of a power failure. An exceptionally small amount of power is required to keep the RTC running.
Technical features
- DS1307 RTC
- I²C interface
- for LIR2032 (not included)
- less than 500 nA in backup mode
SOLDERED DEBO RTC - Developer boards - Real-time clock - RTC, PCF85063A
16.31 EUR
"The RTC (Real Time Clock) is a device that tracks time and date accurately and precisely. Due to its high precision, it is better suited for long-term time tracking than the clocks on microcontrollers.- compatible with Arduino (or a compatible board such as Dasduino)
- extremely low power consumption
- integrated battery holder
- alarm function and interrupt pin
- uninterrupted time tracking even in the event of a power failure
The RTC (Real Time Clock) is characterized by its high accuracy, which makes it particularly suitable for applications where long-term time tracking is required. It is compatible with Arduino (or a compatible board such as Dasduino) and can be operated with extremely low power consumption. Thanks to the integrated battery holder, time tracking is maintained even in the event of a power failure. The alarm function and interrupt pin allow a microcontroller to go into sleep mode and only be reactivated when an alarm is triggered by the RTC.
The built-in battery holder (battery not included) ensures that real-time tracking is not affected even in the event of a power failure.
Technical data
- Communication: I2C
- RTC IC: PCF85063A
- Voltage: 0.9 V ... 5,5 V
- easyC/Qwiic compatibility
- Dimensions: 38 x 22 mm
The RTC offers a precise and reliable solution for long-term time tracking in applications that require accurate time recording. It is compatible with common microcontroller boards and ensures efficient and continuous time tracking thanks to its low power consumption and alarm function.
easyC
easyC is a robust connection system that optimizes the connection using JST-SH compatible connectors (JST 4-pin) of microcontrollers, sensors and actuators. It offers solderless connections, serial connections of multiple devices (daisy-chaining), error-free design, parallel connection, universal compatibility and intermediate compatibility with Qwiic (Sparkfun connection system), simplifying prototype development.

FREI DS 3234 S - Real-time clock, clock/calendar, SO-20
18.53 EUR
The DS3234 is a low-cost, extremely accurate SPI™ bus real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The DS3234 incorporates a precision, temperature-compen-sated voltage reference and comparator circuit to monitor V, CC. When V, CC drops below the power-fail voltage (V, PF), the device asserts the RST output and also disables read and write access to the part when V, CC drops below both V, PF and V, BAT. The RST pin is monitored as a pushbutton input for generating a µP reset. The device switches to the backup supply input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3234 is available in commercial and industrial temperature ranges, and is offered in an industry-standard 300-mil, 20-pin SO package.

11.66 EUR
The DS1302 trickle-charge timekeeping chip contains a real-time clock/cale ndar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial inte rface. The real-time clock/ca lendar provides seconds, minutes, hours, day, date, month, and y ear information. The end of the mont h date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Interfacing the DS1302 with a microprocessor is simplifi ed by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: CE, I/O (data line), and SCLK (serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1 µ W.
