• Performance Specifications - 143MHz clock frequency with 5.5ns access time, supporting applications requiring deterministic memory access patterns.
• Power Supply - Single 3V to 3.6V supply voltage, simplifying power distribution and supporting standard 3.3V logic families.
• Package Format - 90-pin LFBGA (8x13mm) footprint, offering compact board space utilization with good thermal characteristics for commercial environments.
• Temperature Range - Commercial grade operation from 0°C to 70°C, suitable for indoor equipment and controlled-environment applications.
• Interface - Parallel memory interface providing direct processor connectivity without requiring serial-to-parallel conversion overhead.

Typical Applications

• Consumer Electronics - This SDRAM serves as working memory in set-top boxes, digital cameras, and multimedia devices where the 256Mbit capacity handles frame buffers and application code execution within commercial temperature environments.
• Networking Equipment - The parallel interface and 143MHz operation support packet buffering in switches and routers deployed in climate-controlled data centers and telecommunications facilities.
• Office Automation - Printers, scanners, and multifunction devices utilize this SDRAM for image processing and document handling tasks that benefit from the 32-bit wide data path.
• Embedded Computing - General-purpose embedded systems leverage this memory for program execution and data storage in applications where the commercial temperature range aligns with indoor deployment requirements.

Unique Advantages

• Proven SDRAM Technology: Well-established synchronous DRAM architecture offers predictable behavior and broad ecosystem support, reducing integration risk.
• Single Voltage Operation: The 3V to 3.6V supply range eliminates multiple voltage rails, simplifying power supply design and reducing component count.
• Compact LFBGA Footprint: The 8x13mm package provides high pin density while maintaining reasonable PCB routing requirements for mid-complexity boards.
• 32-Bit Wide Data Path: The x32 organization reduces the number of memory devices needed compared to narrower configurations, potentially lowering BOM costs in high-throughput applications.
• Parallel Interface Simplicity: Direct connection to processor memory buses avoids the latency and complexity of serial memory interfaces in legacy or cost-sensitive designs.
