• Fast Access Time - 0.5ns access time with 15ns write cycle time ensures responsive read and write operations for time-sensitive applications
• Low Voltage Operation - 1.7V to 1.9V supply voltage reduces power consumption while maintaining performance
• Compact Package - 84-pin TWBGA (8x12.5mm) offers space-efficient board layout for high-density designs
• Standard Temperature Range - 0°C to 70°C (TA) operating range suits commercial and industrial applications

Typical Applications

• Embedded Computing Systems - This DDR2 SDRAM serves as main memory or buffer storage in embedded processors and microcontrollers where the parallel interface and moderate density balance performance with system complexity.
• Networking Equipment - The fast access time and parallel data bus make this memory suitable for routers, switches, and network appliances that require temporary packet buffering and routing table storage.
• Consumer Electronics - Set-top boxes, digital displays, and multimedia devices benefit from the 266MHz operation and compact package when implementing frame buffers or application memory.
• Industrial Control Systems - PLCs and machine controllers utilize this SDRAM for program execution and data logging where the 0°C to 70°C temperature range covers typical factory floor environments.
• Medical Instrumentation - Diagnostic equipment and patient monitoring systems leverage the reliable volatile memory for real-time data processing and temporary storage of measurement results.

Unique Advantages

• Simplified BOM Management: Single-chip 256Mbit capacity reduces component count compared to multiple lower-density devices, lowering assembly costs and improving reliability
• Design Flexibility: 16M x 16 organization provides word-aligned access patterns that simplify memory controller design for 16-bit or 32-bit processor architectures
• Power Efficiency: Low voltage operation (1.7V-1.9V) reduces thermal dissipation and extends battery life in portable or energy-conscious designs
• Board Space Optimization: Compact 8x12.5mm TWBGA footprint maximizes available PCB area for other components in space-constrained applications
• Proven Technology: DDR2 SDRAM represents mature, well-supported technology with established design practices and readily available reference materials
• Active Lifecycle Status: Ongoing production availability ensures long-term supply for product lifecycles and field replacements
