• Interface and Voltage: LVTTL-compatible interface with 3V to 3.6V supply voltage ensures compatibility with standard 3.3V logic families and simplifies power supply design.
• Compact Package: 90-pin TFBGA package measuring 8x13mm provides high density in a small footprint, enabling compact PCB layouts for portable and embedded systems.
• Temperature Range: Operates reliably across 0°C to 70°C ambient temperature range, suitable for commercial and industrial computing environments.
• Active Lifecycle: Currently in active production status, ensuring long-term availability for new designs and product lifecycle management.

Typical Applications

• Embedded Computing Systems: This SDRAM provides working memory for embedded processors and microcontrollers in industrial control systems, where the 8M x 32 organization matches common 32-bit processor architectures and the 166MHz speed supports real-time data processing requirements.
• Networking Equipment: Serves as packet buffer memory in routers, switches, and network interface cards where fast access time enables efficient data throughput and the compact TFBGA package fits dense networking hardware designs.
• Consumer Electronics: Powers user interface responsiveness and application execution in set-top boxes, digital displays, and multimedia devices where the combination of capacity, speed, and small footprint supports feature-rich product designs.
• Test and Measurement Instruments: Provides data acquisition buffering and waveform storage in oscilloscopes and logic analyzers where synchronous operation at 166MHz enables high-speed sample capture and processing.
• Point-of-Sale Terminals: Delivers system memory for POS devices and payment terminals operating in commercial environments where the 0-70°C range covers typical retail conditions and active lifecycle status supports long product deployment cycles.

Unique Advantages

• 32-bit Native Interface Reduces Component Count: The x32 data width directly matches 32-bit processor buses without additional external logic, simplifying board design and reducing BOM costs compared to using multiple narrower memory devices.
• Industry-Standard LVTTL Interface Simplifies Integration: Direct compatibility with 3.3V logic eliminates level-shifting circuits and reduces design complexity when interfacing with standard microprocessors and FPGAs.
• Synchronous Architecture Improves System Timing: Clock-synchronized operation simplifies timing design and validation compared to asynchronous memory, reducing development time and improving signal integrity in high-speed systems.
• Space-Efficient TFBGA Package: The 90-ball fine-pitch BGA footprint delivers high pin density in minimal board space, enabling more compact product designs or freeing PCB area for additional functionality.
• Commercial Temperature Range Covers Wide Application Scope: The 0-70°C operating range addresses most commercial, office, and light industrial environments without requiring expensive extended-temperature components.
• Active Production Status Ensures Supply Continuity: Current active lifecycle status provides confidence for new design commitments and reduces long-term obsolescence risks in products with multi-year lifecycles.
