An RTC module that can replace RX-8025SA (RX-8111CE package conversion module)
RTC (Real_Time Clock) is called a "clock chip". Its interrupt function can regularly wake up devices in the network, allowing other modules of the device to sleep most of the time, thus greatly reducing the overall power consumption of the device. At present, RTC is widely used in various fields such as security monitoring, industrial equipment, smart meters, cameras, and 3C products.

MCU bosses, which crystal oscillators did you choose? (one)
MCU (MicrocontrollerUnit), also known as microcontroller or microcontroller, appropriately reduces the frequency and specifications of the CPU, and integrates peripherals such as memory (Memory), counter (Timer), USB, A/D conversion, UART, PLC, DMA, etc. The interface and even the LCD driver circuit are integrated on a single chip to form a chip-scale computer. Thereby realizing the function of terminal control, it has the advantages of high performance, low power consumption, programmability, and high flexibility.

The RTC is in uninterrupted working condition and requires an independent backup battery to ensure Power is supplied at all times, even if the equipment is powered off, it will not affect the operation of the RTC. Therefore, prepare The performance of the battery directly determines whether the RTC can operate stably and reliably. How to make the RTC module achieve low power consumption and long life, which is equipped with Panasonic Chi Bian played an important role in it.

STM32 chip + 8M crystal oscillator + 32.768Khz crystal oscillator matching selection reference plan
The STMicro Electronics Group was established in June 1987 through the merger of Italy's SGS Microelectronics and France's Thomson Semiconductor. Since 1999, ST has always been one of the world's top ten semiconductor companies. The STM32 series of products is a high-performance, low-cost, low-power MCU launched by ST in 2007 based on the ARM@Cortex-M core. The STM32 series is the earliest product series launched and is currently the most commonly used product series.
