I. Core Technical Parameters and Characteristics

Basic Specifications

• Capacity and Bit Width: 4Gb (256Mx16), supporting dual-channel architecture. A single chip can form a 4GB memory module.

• Data Rate: The mainstream version is DDR4-2400 MT/s (equivalent frequency of 2400MHz). Some sources indicate that a DDR4-2666 MT/s version exists, which needs to be confirmed based on specific application scenarios.

• Voltage: The standard operating voltage is 1.2V, supporting a ±5% fluctuation range (1.14V~1.26V) and complying with JEDEC specifications.

• Packaging: FBGA-96 Ball Grid Array (BGA) packaging, featuring a compact size (approximately 10mm x 10mm), suitable for high-density PCB layouts.

Physical and Environmental Adaptability

• Temperature Range:

• Standard Version: 0°C ~ 95°C (commercial grade).

• Industrial-Grade Version (e.g., UHIR): -40°C ~ 95°C, suitable for extreme environments.

• RoHS and Environmental Compliance: Lead-free and halogen-free, meeting EU environmental directives.

Timing and Performance

• Typical Timing: CL17-17-17-39 (for DDR4-2400), supporting XMP (Extreme Memory Profile) automatic overclocking configuration.

• Bandwidth: The theoretical peak bandwidth is 38.4GB/s (calculated as 2400MT/s x 16bit/8), which can meet the data throughput requirements of mid-to-high-end CPUs.

II. Industry Application Scenarios and Cases

Consumer Electronics Field

• Solid-State Drive (SSD) Cache:

  Entry-level NVMe SSDs such as the Toshiba RC500 adopt H5AN4G6NBJR-UHC as an independent cache to improve random read/write performance. In actual tests, the 4K read speed can reach 1490MB/s and the write speed 1376MB/s, significantly optimizing system response.

• Game Console and PC Memory:

  When paired with AMD Ryzen 5 or Intel i5 processors, a single 4GB module can form 8GB of dual-channel memory, enabling smooth operation of mid-graphics-quality games like League of Legends.

Industrial Control and Automation

• PLC (Programmable Logic Controller):

  The industrial-grade version (e.g., UHIR) is selected for Siemens S7-1500 series PLCs, which operate stably in low-temperature environments of -40°C and support real-time data processing and equipment control.

• Smart Meters and IoT Terminals:

  Huawei IoT gateways adopt H5AN4G6NBJR-UHC, combined with low-power design, to achieve 24/7 data collection and edge computing.

Automotive Electronics

• In-Vehicle Infotainment (IVI) System:

  The central control screen module of Tesla Model 3 integrates this chip, supporting multi-task processing (navigation, media playback, vehicle settings) and ensuring a smooth, lag-free interface.

• Autonomous Driving Domain Controller:

  NVIDIA Orin platforms use H5AN4G6NBJR-UHC to achieve high-bandwidth data caching, meeting the real-time processing needs of LiDAR point clouds and camera images.

III. Selection Recommendations and Procurement Guide

Version Differentiation Tips

• Model Suffix Interpretation:

• UHC: Standard industrial grade (0°C~95°C).

• UHIR: Wide-temperature industrial grade (-40°C~95°C), with a price approximately 15% higher.

• Chip Quality Screening:

  Read SPD (Serial Presence Detect) information using tools like CPU-Z or Thaiphoon Burner. Prioritize selecting CJR/DJR versions (Tier 2), which have better overclocking potential than JJR versions (Tier 3).

IV. Future Technological Evolution and Outlook

Process Upgrade

Interface and Protocol

• Popularization of DDR4-3200: As Intel Raptor Lake Refresh processors support DDR4-3200, H5AN4G6NBJR-UHC may launch a high-frequency version (e.g., UHCR) in the future to meet the needs of new platforms.
