## Electronic Overview: CSTCC3M64G56Z-R0 The **CSTCC3M64G56Z-R0** is a specific type of electronic component known as a **Ceramic Resonator** with built-in load capacitors. It is manufactured by **Murata Electronics** and is part of the CERALOCK® family. These components are primarily used as timing elements in microcontrollers and other digital ICs, serving as a cost-effective alternative to quartz crystals. --- ### Key Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Ceramic Resonator (SMD) | | **Frequency** | 3.64 MHz | | **Frequency Tolerance** | ±0.5% | | **Built-in Capacitance** | 47 pF (Typical) | | **Operating Temperature** | -20°C to +80°C | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 7.2mm x 3.0mm (Approx.) | --- ### Internal Structure and Parts The "CSTCC" series is distinct because it is a **3-terminal device**. Here is how the internal parts function: 1. **Piezoelectric Ceramic Element:** The core "brain" of the component. It utilizes the mechanical vibration of the ceramic material to create a stable electrical frequency. 2. **Built-in Load Capacitors:** Unlike standard 2-pin crystals that require external capacitors on the PCB, this part has two capacitors integrated into the package. 3. **Electrodes:** Metallic layers that connect the ceramic element to the external terminals. 4. **Base and Cap:** A ceramic substrate and a protective wash-resistant cover to ensure durability during the soldering process. --- ### Pin Configuration | Pin Number | Function | Description | | :--- | :---: | :--- | | **1** | Input | Connected to the oscillator input of the IC. | | **2** | Ground | Connected to the system ground (GND). | | **3** | Output | Connected to the oscillator output of the IC. | --- ### Why use this part? * **Space Saving:** By integrating the load capacitors, it reduces the number of external components required on the PCB. * **Stability:** While not as precise as a quartz crystal, it is much more stable and accurate than a standard RC (Resistor-Capacitor) oscillator. * **Cost-Efficiency:** Ideal for consumer electronics where extreme precision (like high-speed networking) isn't required, but cost and size are critical. ---
