The RTC-4701JE:B is a Real-Time Clock (RTC) module categorised under Clock/Timing - Real Time Clocks. It is designed to measure and keep track of time utilising synchronised atomic clocks. RTCs are commonly used in consumer devices, such as digital cameras and personal computers, to streamline operations such as automated power on/off, wake-up/off timer, sleep mode and system clock re-synchronisation. The RTC-4701JE:B is made compliant to the European Union\'s Restriction on the Use of Hazardous Substances (RoHS) directive and therefore does not contain or use hazardous materials or chemicals which could be detrimental to the environment.

The RTC-4701JE:B consists of a microcontroller and a high-precision quartz crystal oscillator. Oscillator stability is achieved through sophisticated frequency adjustment and trimming circuits. Its integrated EEPROM allows for data storage, automatic start-up and permanent storage of important clock data and configuration information. The RTC-4701JE:B can also integrate temperature-compensated crystal oscillators (TCXO) to achieve a drift rate of only one microtick per second.

This RTC module is designed to be used on flexible application platforms, such as embedded systems, as well as wired and wireless internet-connected devices and industrial IoT market segments. This RTC module is particularly suitable for applications which require precise timekeeping such as alarm clocks, voice and video conferences, virtual reality, and others. Through the integration of a programmable register, the module allows for applications which require periodic engagements, such as resetting or changing time parameters.

RTC-4701JE:B\'s working principle depends on the use of a very precise quartz crystal oscillator, which measures frequency in hertz (Hertz, Hz). The RTC module is powered by a battery and an electronic circuit which provides a stable clock source in the range from 1Hz to onboard up to 200MHz, depending on the oscillator used. As clock frequency may drift over time, an external time source, such as a computer or an atomic clock, is likely to be needed for Synchronisation. Synchronisation can be achieved through the unit’s crystal oscillator, RTC output, or direct digital input.

Due to its versatile integration options, the RTC-4701JE:B is suitable for a variety of applications in a wide range of industries, from consumer devices to industrial and medical systems. The RoHS compliance of this RTC module also makes it a unique choice for renewable energy applications, such as energy storage and smart grids. It is also suitable for integration in smart home platforms and in wearable devices.

The RTC-4701JE:B offers a power saving design, supporting low current consumption and standby mode. The chip supports battery backup, allowing for continued operation in the event of a power failure. In addition, the compatibility with industry standard I2C, SPI and UART serial buses, coupled with its integration and ease of use in application platforms, makes the RTC-4701JE:B a reliable, reliable and cost-effective choice for precision timekeeping.
