The **CSTCC3M64G53-R0** is a specific model of a **Ceramic Resonator** manufactured by Murata Electronics. These components are used to provide a stable clock signal for microcontrollers and other digital circuits. --- ### 1. Technical Specifications The part number encodes specific technical details. Here is the breakdown of its primary characteristics: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 3.64 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | Internal (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 7.2mm x 3.0mm (3-terminal) | --- ### 2. Key Features and Design * **Built-in Capacitors:** Unlike standard quartz crystals that require two external ceramic capacitors to complete the oscillation circuit, the "CSTCC" series includes these capacitors internally. This saves PCB space and reduces the Bill of Materials (BOM). * **Piezoelectric Ceramic Technology:** It utilizes the mechanical resonance of piezoelectric ceramics. While less precise than quartz crystals, they are much more cost-effective and have faster "start-up" times. * **Three-Terminal Package:** 1. **Input** (Oscillation) 2. **Ground** (Common) 3. **Output** (Oscillation) --- ### 3. Applications The 3.64 MHz frequency is commonly used in legacy or specific low-power timing applications, including: * **Microcontrollers:** Serving as the external clock source for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Remote controls, toys, and basic household appliances. * **Communication Equipment:** Low-speed data processing units. --- ### 4. Comparison: Resonator vs. Crystal | Feature | Ceramic Resonator (CSTCC) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Cost** | Low | Higher | | **Size** | Small (Integrated Caps) | Larger (External Caps needed) | | **Start-up Time** | Very Fast | Slower |
