Crystal oscillator is a commonly used clock component in circuits. It is made of quartz crystal sheets with piezoelectric effect and inverse piezoelectric effect. The role of the crystal oscillator is to generate the clock frequency. Today I will introduce to you common frequency 4M, 6M, and 8M crystals (passive, without voltage).
Advantage: 1. It has the characteristics of high voltage, wide use, small self-discharge, and high reliability for a long time. 2. Panasonic has a rich product line of primary batteries that can be used in a variety of industries and uses. 3. Terminals, plastic sealing and secondary processing can be carried out according to customer needs.
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 (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.
"Tang Electronics" cooperated with Huada MCU research and development and conducted rigorous crystal oscillator matching experiments on the HC32LXXX series MCU.
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.
