"MCU Chip + Crystal Oscillator": Which Crystal Oscillators Do MCU Manufacturers Choose?

              MCU (Microcontroller Unit), also known as a microcontroller or single-chip microcomputer, is a chip-scale computer that appropriately reduces the frequency and specifications of the CPU while integrating peripherals such as memory (Memory), timers (Timer), USB interfaces, A/D converters, UART (Universal Asynchronous Receiver/Transmitter), PLC (Programmable Logic Controller) functionality, DMA (Direct Memory Access), and even LCD drive circuits onto a single chip. This integration enables MCUs to perform terminal control functions, boasting high performance, low power consumption, programmability, and high flexibility. With its exceptional performance, low power consumption, programmability, and flexibility, the MCU has become an indispensable core component in modern electronic systems. Its wide range of applications and immense value are leading terminal control fields such as smart homes and intelligent security towards a smarter, more efficient, and convenient future. For users pursuing a high-quality life experience, the MCU is undoubtedly an ideal choice for realizing intelligent living.

During the initial design phase of the MCU, the following crystal oscillators were selected (for reference only).
