• Power Supply - Operates on 1.7V to 1.9V supply voltage, aligning with standard DDR2 power requirements for energy-efficient system integration.
• Interface - SSTL_18 (Stub Series Terminated Logic) interface ensures signal integrity and reliable high-speed data transfer.
• Extended Temperature Range - Rated for -40°C to 95°C case temperature operation, supporting designs exposed to wide thermal excursions.
• Compact Package - 84-TFBGA (8mm x 12.5mm) package provides space-efficient board-level integration.

Typical Applications

• Industrial Automation - This DDR2 SDRAM provides reliable memory buffering for programmable logic controllers (PLCs) and human-machine interfaces where the extended temperature range ensures stable operation in factory floor environments subject to thermal stress.
• Networking Equipment - The 512Mbit capacity and 400MHz clock frequency support packet buffering and data routing in switches, routers, and telecommunications infrastructure operating in temperature-variable equipment closets.
• Embedded Computing Systems - Serves as main or auxiliary memory in embedded platforms requiring moderate density and speed, particularly in applications deployed outdoors or in non-climate-controlled enclosures.
• Test and Measurement Instruments - Provides data acquisition buffering and waveform storage in portable or benchtop instruments where compact packaging and temperature tolerance are essential.
• Medical Devices - Supports diagnostic equipment and patient monitoring systems where reliable memory operation across temperature variations contributes to device dependability.

Unique Advantages

• Proven DDR2 Ecosystem Compatibility: Leverages mature DDR2 controller IP and design practices, reducing development risk and accelerating time-to-market for new platforms.
• Extended Temperature Resilience: The -40°C to 95°C case temperature rating reduces the need for costly thermal management in systems deployed in harsh or variable environments.
• Balanced Density and Speed: 512Mbit capacity and 400MHz operation provide a practical balance for embedded applications without the complexity or power demands of higher-speed or larger-density alternatives.
• Compact Footprint: The 84-FBGA package minimizes PCB area consumption, supporting higher integration density in space-constrained designs.
• Flexible Word Organization: The 32M x 16 configuration aligns naturally with 16-bit or 32-bit processor architectures, simplifying memory subsystem design.
• Reliable Alliance Memory Source: Alliance Memory provides long-term product availability and stable supply, supporting extended product lifecycles common in industrial and embedded markets.
