Common 32.768KHz crystal oscillator brands and models comparison table + real-time clock RTC

Common 32.768KHz crystal oscillator brands and models comparison table + real-time clock RTC

The 32.768KHz crystal oscillator is a standard frequency. The application of crystal oscillator frequency mainly has the following parameters: size, load capacitance, frequency deviation, and application range. According to size and shape, they are mainly divided into plug-ins and patches. 32.768KHz is the most commonly used crystal oscillator frequency on the market today. However, 32.768KHz has many sizes and brands. In order to meet the needs of many buyers, the following are the commonly used 32.768K crystal oscillator models and corresponding brand material numbers (the following brands and material numbers of the same size can be interchanged), which are widely used in electricity meters, water meters, gas meters, heat meters, gas meters, and industrial control Instruments etc. "Tang Hui Electronics" carefully organized the data and compiled the major brands of 32.768KHz crystal oscillators as shown below:

Which crystals did the Silicon Labs MCU boss choose when doing the original design?

Which crystals did the Silicon Labs MCU boss choose when doing the original design?

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.
