The EPSON's real-time clock module RX8010SJ has rich timing functions and ultra-low power consumption features

The temperature controller is used to control the temperature of the equipment. At present, the temperature controller on the market is used to control the floor heating air conditioning, water heater, central fresh air system and other equipment. With the concept of smart home deeply rooted in people, people also expect that the thermostat can not only control "accurate", but also control "intelligent". In order to realize the intelligent control, the temperature controller generally needs the help of the real-time clock module, and the EPSON RX8010SJ is such a very suitable real-time clock module.

 Rich alarm clock and timing functions, help to achieve personalized control scene

 Timing switch is a very common intelligent control requirement, the simplest, such as requiring that the temperature controller can start or turn off the controlled device at a fixed time every day. RX8010SJ The alarm clock function, week, date, hour, minute four parameters can be set separately, through the combination of week + hour + minutes or date + hour + minute, to achieve a variety of alarm clock function. For the week + hour + minutes combination, you can output alarm signals at 7 am each day from Monday to Friday, or output alarm signals at 30 minutes of each hour on Saturday and Sunday. For the combination of date + hour + minutes, output the alarm signal at 7 am on the first day of each month; or the alarm signal at 6:69 am each day; or the alarm signal at 30 minutes on each hour on the 15th of each month. You can see that the RX8010SJ alarm clock is very powerful, helping users to achieve a variety of personalized switch Settings.

 In addition to the alarm clock, the RX8010SJ also offers a timer function that allows the thermostat to achieve regular temperature adjustments, such as by rising the temperature once every two minutes. RX8010SJ The timer provides the shortest timing cycle of 244.14us, the longest of 65535 hours, the range of timing cycle is very wide, so that users can achieve different fine degrees of temperature change control.

 RX8010SJ Also provides the time update outage function, can set the output outage signal per second or per minute, help the thermostat to achieve more periodic tasks.

RX8010SJ The above three timing functions are provided, each of which has a corresponding event marker bit, and the corresponding marker bit is placed when the timing event occurs. Therefore, the above three timing functions can be set at the same time without interfering with each other. After receiving the interrupt signal from the output of RX8010SJ, the main control can determine which timing event has occurred by inquiring the corresponding marker bit without causing confusion. This means that RX8010SJ allows users to set different timing tasks at the same time to complete more complex controls, thus greatly improving the competitiveness of the product.

Low power consumption, after the main power supply is easy to achieve time retention

Thermostats usually have LCD screens that display the calendar information provided by the real-time clock module. If the main power supply of the temperature controller is cut off, after the power supply is restored, the screen is generally required to continue to display the correct time information, which requires the real-time clock module to support the backup power supply. RX8010SJ Although there is no backup power supply pin, it only needs to add an additional SOT 23 package co-cathode diode and a small button battery to the circuit to achieve backup power supply. The timing of RX8010SJ keeps the power consumption very low, under the 3V power supply condition, the maximum is only 320 nA. A small button battery with a 40 mAh capacity can be maintained for more than 10 years. It can be seen that the RX8010SJ can easily meet the requirements of the thermostat for timekeeping
