The part number **JH177128160ACNDMNFZCWC** refers to a high-performance **eMMC (Embedded MultiMediaCard)** storage module, typically manufactured by **SK Hynix**. This component is a non-volatile memory solution used in mobile devices, automotive systems, and embedded hardware. --- ### 1. Component Overview An eMMC combines NAND flash memory with an integrated controller. This simplifies the hardware design because the controller manages error correction (ECC), wear leveling, and bad block management internally. | Feature | Specification Details | | :--- | :--- | | **Category** | Integrated Circuits (IC) - Memory | | **Memory Type** | FLASH - NAND (MLC or TLC) | | **Interface** | eMMC 5.1 (High-speed HS400 support) | | **Package Type** | FBGA (Fine-pitch Ball Grid Array) | | **Pin Count** | 153-ball (standard for eMMC) | --- ### 2. Breakdown of the Part Characteristics While manufacturers use proprietary nomenclature, the string identifies specific architectural traits: * **Capacity:** Based on the internal density codes, this module typically represents a **128GB** storage capacity. * **Voltage:** Operates on dual voltage rails: * **VCC (NAND):** 3.3V * **VCCQ (I/O):** 1.8V or 3.3V * **Performance:** Designed for high-speed data transfer, reaching read speeds up to 400MB/s under the HS400 protocol. --- ### 3. Key Electronic Functions 1. **Integrated Controller:** Handles the flash file system, preventing the host CPU from having to manage raw NAND flash complexities. 2. **Health Monitoring:** Supports "Device Health Report" features, allowing the system to monitor the remaining life of the flash cells. 3. **Command Queuing:** Improves random read/write performance by allowing the controller to optimize the execution order of commands. 4. **Secure Purge:** Includes hardware-level support for secure data erasure and write protection. --- ### 4. Common Applications * **Mobile Handsets:** Main storage for OS and user data. * **Automotive Infotainment:** Storage for maps, firmware, and media. * **Single Board Computers (SBCs):** Used in industrial IoT gateways. * **Smart TVs:** Fast booting and application storage.
