The **M2AS1-A442-R2/N** is a high-performance **M.2 Solid State Drive (SSD)** part number typically associated with industrial-grade storage solutions (often manufactured by companies like Innodisk or similar industrial suppliers). Below is the technical breakdown of its electronic parts and specifications. --- ### 1. General Specifications This drive is designed for embedded systems, automation, and industrial computing where reliability is prioritized over consumer-level peak speeds. | Feature | Specification | | :--- | :--- | | **Form Factor** | M.2 2242 (SATA) | | **Interface** | SATA III 6.0 Gb/s | | **Capacity** | Typically 128GB to 256GB (based on the "A442" density code) | | **Flash Type** | 3D TLC (Triple-Level Cell) | | **Operating Temp** | Standard (0°C ~ +70°C) or Wide (-40°C ~ +85°C) | --- ### 2. Electronic Component Breakdown The internal PCB (Printed Circuit Board) consists of three primary electronic segments: #### A. The Controller (The Brain) The controller manages the data flow between the SATA interface and the NAND flash. * **Functions:** Error Correction Code (ECC), Wear Leveling, and Bad Block Management. * **Garbage Collection:** Sophisticated algorithms to maintain write speeds over time. * **S.M.A.R.T Support:** Monitoring electronic health attributes. #### B. NAND Flash Memory (Storage) The "A442" designation in the part number usually refers to the specific stack of **3D TLC NAND**. * **Vertical Stacking:** Unlike older 2D NAND, 3D NAND stacks cells vertically to increase density and reduce electrical interference between cells. * **Endurance:** Industrial versions often feature higher P/E (Program/Erase) cycles than consumer drives. #### C. Power Management & Circuit Protection * **Voltage Regulators:** Converts the 3.3V supplied by the M.2 slot to the internal voltages required by the NAND and Controller. * **Thermal Throttling:** Electronic sensors that reduce performance if the components exceed safe operating temperatures. * **Decoupling Capacitors:** Small surface-mount capacitors that stabilize voltage and filter out electronic noise. --- ### 3. Pinout and Physical Interface Since this is an **M.2 2242** form factor, it uses the following physical characteristics: * **Keying:** Usually **B+M Key** (two notches) to ensure compatibility with various M.2 slots. * **Dimensions:** 22mm wide x 42mm long. * **Connector:** 75-position edge connector. --- ### 4. Part Number Decoder (Typical) | Segment | Meaning | | :--- | :--- | | **M2AS1** | M.2 SATA Series 1 | | **A442** | Capacity/Density Identifier (e.g., 128GB/256GB) | | **R2** | Hardware Revision 2 | | **N** | Internal Firmware/Feature code (Standard) |
