Main Body

Part 1: Technical Specifications and Architecture

The K4A8G165WC-BCTD is a 8Gb (Gigabit) DDR4 SDRAM organized as 512M x 16 bits. This means it has a data bus width of 16 bits, making it ideal for applications requiring high bandwidth in a compact footprint. The “BCTD” suffix indicates a specific speed grade and temperature range, which we will unpack below.

• Speed Grade and Timing: This particular variant operates at a PC4-2400 (DDR4-2400) speed rating, with a CL17 (CAS Latency) timing. This translates to a data transfer rate of 2400 MT/s (Megatransfers per second). For many mid-to-high-end embedded systems, this speed offers an excellent balance between performance and power consumption. The device supports tRCD (RAS to CAS Delay) and tRP (Row Precharge Time) of 17 clock cycles, ensuring stable operation under heavy memory loads.

• Voltage and Power Efficiency: Operating at a standard 1.2V core voltage, the K4A8G165WC-BCTD adheres to the JEDEC DDR4 standard, consuming significantly less power than its DDR3 predecessors (which typically run at 1.5V). It also features an internal VREF (Voltage Reference) generator, which improves signal integrity and reduces external component count. Additionally, it supports self-refresh and auto-refresh modes, with a maximum refresh interval of 64ms at normal operating temperatures.

• Package and Pinout: The chip comes in a 78-ball FBGA (Fine-Pitch Ball Grid Array) package, measuring just 10mm x 14.5mm. This compact form factor is essential for space-constrained designs like mini-PCs, networking routers, and industrial single-board computers. The pinout is fully JEDEC-compliant, ensuring drop-in compatibility with other DDR4 components of the same density and bus width.

• On-Die Termination (ODT): The K4A8G165WC-BCTD includes configurable ODT settings, which help to minimize signal reflections on the memory bus. This is particularly critical when multiple memory modules are connected to the same memory controller, as it ensures clean high-speed signaling without the need for external termination resistors.

Part 2: Application Scenarios and Performance Benefits

The K4A8G165WC-BCTD is not a consumer-grade DRAM module; rather, it is a raw memory IC designed for integration onto custom PCBs. Its primary applications span across several high-growth sectors:

• Networking and Telecommunications: With the explosion of 5G infrastructure and edge computing, routers, switches, and base stations require high-density, low-latency memory. The 16-bit wide data bus of this chip allows for efficient interfacing with network processors, enabling fast packet buffering and routing table storage. The 2400 MT/s speed ensures that data throughput keeps pace with multi-gigabit Ethernet ports.

• Industrial Automation and IoT Gateways: Industrial PCs (IPCs) and programmable logic controllers (PLCs) often operate in harsh environments with wide temperature fluctuations. The BCTD variant is rated for an extended temperature range (-40°C to +95°C) , making it suitable for outdoor and factory-floor deployments. Its robust design ensures data integrity even under vibration and thermal stress.

• Consumer Electronics and Set-Top Boxes: For 4K/8K video streaming and advanced gaming consoles, the memory bandwidth provided by this DDR4 chip is sufficient to handle multiple video streams and complex graphics rendering. Its 8Gb density allows for a total of 1GB of memory per chip, which can be scaled by using multiple chips in parallel.

• Automotive Infotainment and ADAS: As vehicles become software-defined, the demand for reliable memory in infotainment clusters and advanced driver-assistance systems (ADAS) grows. The K4A8G165WC-BCTD meets the AEC-Q100 reliability standards (though specific grade should be confirmed with the manufacturer), ensuring long-term stability in automotive temperature ranges.

Performance Benefit: Compared to older DDR3L parts, this DDR4 chip offers a ~40% increase in bandwidth while reducing power consumption by ~20%. This translates to longer battery life for portable devices and lower cooling requirements for sealed industrial enclosures.

Part 3: Sourcing, Quality Assurance, and Procurement Strategies

When integrating the K4A8G165WC-BCTD into your product, sourcing genuine components is paramount. Counterfeit or recycled memory chips are a significant risk in the electronics industry, leading to intermittent failures and reduced product lifespan. Here are key considerations for procurement:

• Authenticity Verification: Always request the original datasheet and lot traceability codes from your supplier. Genuine Samsung chips will have laser-marked batch numbers that can be cross-referenced with the manufacturer’s database. A reliable distributor will provide coverage for X-ray inspection and electrical testing to confirm the die’s integrity.

• Inventory and Lead Times: Due to global semiconductor supply chain fluctuations, the K4A8G165WC-BCTD may have variable lead times. It is advisable to maintain a safety stock of at least 8-12 weeks of your projected usage. For urgent prototyping needs, look for distributors with real-time inventory and same-day shipping capabilities.

• Why Choose ICGOODFIND: This is where ICGOODFIND becomes a valuable partner. As a specialized electronic component search engine and marketplace, ICGOODFIND aggregates inventory from vetted global suppliers, allowing you to compare pricing and availability for the K4A8G165WC-BCTD instantly. The platform provides full datasheet downloads, RoHS/REACH compliance certificates, and supplier ratings based on historical transaction quality. By using ICGOODFIND, you mitigate the risk of encountering fake or substandard parts, as the platform enforces strict seller verification protocols.

• Cost Optimization: While the unit price of this chip fluctuates with market demand, buying in bulk (e.g., reels of 2,000 pieces) typically yields a 10-15% discount. However, be cautious of “too good to be true” pricing—if a deal is significantly below market average, it likely involves refurbished or pulled components. ICGOODFIND allows you to filter by “new & original” status, ensuring you only see listings for factory-fresh inventory.

Conclusion

The K4A8G165WC-BCTD is a versatile, high-performance DDR4 memory IC that strikes an excellent balance between speed, density, and power efficiency. Its 16-bit bus architecture and extended temperature range make it a preferred choice for networking, industrial, and automotive applications. However, the key to leveraging this component successfully lies in secure sourcing and rigorous quality assurance. By partnering with a transparent platform like ICGOODFIND, engineers and procurement managers can navigate the complex semiconductor market with confidence, ensuring that every chip placed on the PCB is authentic, fully tested, and backed by complete documentation. As technology continues to demand faster and more reliable memory, the K4A8G165WC-BCTD remains a solid, future-proof investment for your next hardware design.
