The **M2AS1-6444-R2/N** refers to a high-performance, small-form-factor storage module, typically associated with industrial or automotive-grade M.2 SSDs (Solid State Drives). These parts are engineered for reliability in harsh environments compared to standard consumer electronics. --- ### 1. Component Overview This part is an **M.2 2242 Form Factor SSD** utilizing a specific interface and NAND configuration designed for embedded systems. | Attribute | Specification | | :--- | :--- | | **Form Factor** | M.2 2242 (22mm width x 42mm length) | | **Interface** | SATA III (6.0 Gb/s) or PCIe NVMe (depending on specific OEM rev) | | **Capacity** | 64GB (Indicated by the "64" in the part number) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **NAND Type** | Typically MLC or Industrial TLC | --- ### 2. Key Electronic Features #### A. Power Management Integrated Circuit (PMIC) The board contains a dedicated PMIC that regulates voltage from the host (3.3V) down to the levels required by the NAND flash and the controller (usually 1.8V and 1.2V). * **Protection:** Includes Over-Voltage Protection (OVP) and Under-Voltage Protection (UVP). #### B. The Controller This is the "brain" of the module. In this specific series, the controller handles: * **Wear Leveling:** Ensures data is written evenly across the NAND cells to prevent premature failure. * **ECC (Error Correction Code):** Detects and fixes bit errors that occur during high-temperature operations. * **Bad Block Management:** Identifies and maps out defective memory sectors. #### C. NAND Flash Memory The storage medium itself. The "R2" revision often indicates a transition to a more modern 3D NAND architecture, which offers: * Higher data density. * Lower power consumption per GB. * Improved endurance cycles (TBW - Total Bytes Written). --- ### 3. Pinout and Interface The M.2 connector on this part usually follows the **B+M Keying** to ensure compatibility with various motherboard slots. ```markdown Pin Range | Functionality ----------|--------------------------------------------- 1 - 11 | Ground and 3.3V Power Supply 12 - 19 | Config Pins (Identify the module to the BIOS) 20 - 75 | High-speed Data Differential Pairs (TX/RX) ``` --- ### 4. Technical Reliability Ratings Because this is an industrial-grade part ("N" suffix often denoting specific environmental certifications), it includes: 1. **Shock/Vibration Resistance:** Designed to withstand high G-forces in automotive or factory automation. 2. **Thermal Throttling:** The electronic firmware will automatically reduce speeds if the controller detects temperatures exceeding 85°C to prevent hardware damage.
