The part number **47LPQ-A1YR-R** refers to a high-performance, low-power memory component, specifically a **LPDDR4x (Low Power Double Data Rate 4x)** DRAM module. These chips are commonly used in mobile devices, automotive systems, and IoT hardware where energy efficiency and high bandwidth are critical. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Memory Type** | LPDDR4x | | **Data Rate** | Up to 4266 Mbps | | **Voltage (VDDQ)** | 0.6V (Ultra-low voltage for power saving) | | **Core Voltage (VDD1/VDD2)** | 1.8V / 1.1V | | **Interface** | LVSTL (Low Voltage Swing Terminated Logic) | | **Configuration** | Likely 2GB to 8GB (depending on density variant) | | **Packaging** | FBGA (Fine-pitch Ball Grid Array) | --- ### 2. Breakdown of the Part Number Components While specific manufacturers (like Micron, Samsung, or Winbond) have slight variations, the string generally breaks down as follows: * **47L**: Identifies the product family as Low Power DDR memory. * **PQ**: Refers to the specific architecture or density bin. * **A1**: Designates the revision or generation of the silicon die. * **YR**: Indicates the package type (usually a specific ball count, e.g., 200-ball or 272-ball FBGA). * **R**: Typically signifies "Tape and Reel" packaging for automated assembly lines. --- ### 3. Core Advantages 1. **Reduced Power Consumption**: The "x" in LPDDR4x signifies a reduction in I/O voltage (VDDQ) from 1.1V to 0.6V compared to standard LPDDR4, saving up to 15-20% in total power. 2. **High Bandwidth**: Capable of handling massive data throughput for 4K video recording, high-end gaming, and AI processing. 3. **Thermal Efficiency**: Lower voltage leads to less heat generation, making it ideal for fanless, compact enclosures. ### 4. Common Applications * **Smartphones & Tablets**: The primary market for these chips. * **Automotive Infotainment**: Powering dashboards and ADAS (Advanced Driver Assistance Systems). * **Single Board Computers (SBCs)**: High-end edge computing modules. * **Wearables**: High-end smartwatches requiring long battery life. ---
