• Interface - Parallel SDRAM interface provides straightforward integration with microprocessors, FPGAs, and microcontrollers supporting standard SDRAM protocols.
• Package - Compact 90-pin TFBGA (8x13mm) footprint minimizes board space while providing high pin count for wide data buses.

Typical Applications

• Industrial Control Systems - This SDRAM serves as main memory or data buffer in programmable logic controllers (PLCs) and distributed control systems where the extended temperature range ensures consistent operation in factory floor and outdoor industrial environments.
• Embedded Computing - Provides volatile working memory for embedded processors in networking equipment, automation controllers, and industrial computers requiring fast data access and moderate memory capacity.
• Test and Measurement Equipment - Functions as acquisition buffer memory in oscilloscopes, data loggers, and test instruments where the parallel interface supports high-speed data capture from analog-to-digital converters.
• Communications Infrastructure - Serves as packet buffer and routing table memory in network switches, routers, and telecommunications equipment operating in temperature-controlled or environmentally variable locations.
• Medical Devices - Provides data processing memory for medical imaging equipment and diagnostic instruments where reliable operation and adequate capacity support real-time signal processing.

Unique Advantages

• Extended Temperature Reliability: The -40°C to 85°C operating range eliminates the need for additional thermal management in many industrial applications, reducing system complexity and cost.
• 32-bit Data Width Efficiency: Native 32-bit organization matches common processor architectures, eliminating the overhead of multiple narrower memory chips and simplifying board layout.
• Proven SDRAM Technology: Standard synchronous DRAM interface leverages existing controller IP and driver software, accelerating development time compared to specialized memory technologies.
• Balanced Performance Profile: The 133MHz clock and 6ns access time deliver sufficient bandwidth for most embedded applications without the power consumption and complexity of higher-speed alternatives.
• Compact BGA Footprint: Small 8x13mm TFBGA package conserves PCB area while the ball grid array provides reliable connections in vibration-prone industrial environments.
• Active Lifecycle Status: Ongoing availability supports long product lifecycles typical in industrial and infrastructure equipment design.
