Low power RTC real-time clock module RX8010SJ suitable for smart door locks

    With the popularization of smart homes, smart door locks have become an important device for ensuring home safety. As one of the key components of smart door locks, the Real Time Clock (RTC) module is responsible for providing accurate time benchmarks to ensure the normal operation of various time related functions of the door lock. A low-power RTC real-time clock module suitable for smart door locks: Epson's RX8010SJ real-time clock module, with its ultra-low power consumption and high-precision performance, has become an ideal choice for smart door lock applications, providing a stable and reliable time source for smart door locks. Smart door locks have entered more and more households, gradually replacing mechanical locks as the protagonist of home door locks. The operation of door locks, including opening, closing, and other abnormal events, will generate a time stamp, and the generation of this time stamp signal is achieved through the real-time clock module RTC.

The definition and delineation of smart door locks are their so-called "intelligent" features in terms of technology and functionality, including recognition, memory, learning, and other aspects. The smart door lock in the general concept refers to various types of contact/non-contact/remote key/card/buckle locks, as well as password key locks.

The real-time clock module RTC (Real_Time Clock) plays an important role as a steward in smart door lock applications. The real-time clock module RTC provided by EPSON has the function of independently completing timing or event recording. At present, many electronic products have clock timing functions, such as digital products commonly used in our daily lives such as smartphones, laptops, tablets, etc., which are integrated with real-time clocks.

The Epson low-power RTC RX8010SJ applied to smart door locks has the following features:

1. The RX8010SJ has a built-in 32.768KHz crystal oscillator, which eliminates the need for load capacitors and saves more space on the PCB board; And it can prevent engineers from selecting crystals improperly, which may result in performance not meeting standards.

2. The RX8010SJ crystal oscillator has been calibrated before leaving the factory and has better stability.

3. The RX8010SJ has a high overall cost-effectiveness and stable quality.

Epson low-power clock chip module - RX8010SJ, because it integrates a 32.768kHz crystal oscillator and can directly output as a low-speed system clock for MCU, using RX8010SJ has the following benefits:

High precision of 1.5 ± 23ppm ensures time readiness and improves product reliability.

2.In relatively harsh outdoor environments, the RX8010SJ operates at a temperature of -40~85 ℃, which is industrial grade and can ensure that the system clock is not affected by shadows in outdoor environments, improving product experience and quality.

3. The RX8010SJ has a power consumption of only 160nA under normal operation with a supply voltage of 3V. The energy density of a regular CR2032 battery is generally 160mAh, and it can be used for more than 3 years when powered by button batteries. Ensure continuous operation throughout the product lifecycle and improve product stability.

Application of RX8010SJ Real time Clock Module in Intelligent Door Locks

1. Automatic locking and unlocking function: Precise control: The automatic locking and unlocking function of the smart door lock relies on precise time control, and the RX8010SJ provides a reliable time reference to ensure that these functions can be accurately executed at the set time point. For example, the automatic locking or timed unlocking function at night relies on the accurate time output of the RTC module.

2. Event recording and logging functions; Security Tracking: The high-precision timestamp function of RX8010SJ supports event recording and logging of smart door locks, which can accurately record the operation time of each door lock. This is crucial for family safety, as users can promptly detect abnormal activities and take measures by viewing operation logs.

3. Low power standby mode: Energy saving and efficient: During the standby period of the door lock, the ultra-low power consumption characteristics of the RX8010SJ are particularly important. It can ensure that the door lock can still maintain accurate time recording in low-power mode, greatly extending the battery life and improving the overall user experience.

4. Anti disassembly alarm function: Real time monitoring: The anti disassembly alarm function of the smart door lock requires real-time monitoring of the system status, and immediately issues an alarm when an abnormal situation is detected. The RX8010SJ provides an accurate clock reference, ensuring that the anti tamper alarm function can respond quickly and improving the safety performance of the door lock.
