## Overview of CSTCC2M00G53A-R0 The **CSTCC2M00G53A-R0** is a specific model of a **Ceramic Resonator** manufactured by **Murata Electronics**. It belongs to the CERALOCK® family, which is widely used in embedded systems to provide a stable clock signal for microcontrollers and microprocessors. --- ### Technical Specifications | Parameter | Value / Specification | | :--- | :--- | | **Component Type** | Ceramic Resonator | | **Nominal Frequency** | 2.00 MHz | | **Frequency Tolerance** | ±0.5% | | **Load Capacitance** | 15 pF (Built-in) | | **Operating Temperature** | -20°C to +80°C | | **Package / Case** | SMD (Surface Mount Device), 7.2 x 3.0 mm | | **Mounting Type** | Surface Mount | --- ### Key Features 1. **Built-in Load Capacitance:** Unlike standard crystals that require external capacitors to form an oscillation circuit, this part features internal capacitors. This reduces the PCB footprint and simplifies the design. 2. **Frequency Range:** Operating at **2.00 MHz**, it is designed for low-speed timing applications where extreme precision (like that of a quartz crystal) is not required. 3. **High Stability:** It offers better stability than a standard RC (Resistor-Capacitor) oscillator, making it ideal for communication protocols like UART. 4. **Small Form Factor:** The SMD packaging allows for high-density mounting in compact electronic devices. --- ### Pin Configuration and Circuitry The device typically features **3 terminals**: * **Input/Output Pins:** Connected to the XTAL pins of the microcontroller. * **Center Pin:** Connected to **Ground (GND)**. This is because the internal load capacitors are tied to this pin. ```mermaid graph LR MCU_XTAL1 --- Resonator_Pin1 GND --- Resonator_Pin2_Center MCU_XTAL2 --- Resonator_Pin3 ``` --- ### Common Applications * **Microcontrollers:** Serving as the main clock source for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Used in remote controls, toys, and small appliances. * **Automotive:** Found in non-safety critical systems like body control modules or entertainment systems. * **Industrial:** Used in timers and basic logic controllers. --- ### Comparison: Resonator vs. Crystal | Feature | Ceramic Resonator (CSTCC) | Quartz Crystal | | :--- | :--- | :--- | | **Cost** | Lower | Higher | | **Start-up Time** | Very Fast | Slower | | **Accuracy** | Moderate (±0.5%) | High (ppm levels) | | **Size** | Smaller (Integrated Caps) | Larger (External Caps needed) |
