It offers an ideal balance of capacity, speed, and environmental resilience for embedded systems where standard commercial-grade memory components fall short.

Key Features

• High-Performance DDR2 Architecture - 333MHz clock frequency with 4.5ns access time provides responsive data throughput for real-time industrial control systems and automotive infotainment platforms.
• 256Mbit Capacity in 16M x 16 Configuration - Parallel memory organization optimized for 16-bit data bus architectures common in embedded microcontrollers and DSP systems.
• Extended Industrial Temperature Range - Qualified for -40°C to 105°C ambient operation, ensuring reliable memory retention and access in harsh factory floors, outdoor enclosures, and automotive engine compartments.
• Low Voltage Operation - 1.7V to 1.9V supply voltage reduces power consumption and heat generation in space-constrained industrial equipment and battery-powered automotive modules.
• Compact 84-TWBGA Package - 8mm x 12.5mm thin very-fine-pitch ball grid array minimizes PCB footprint for dense multi-layer board designs in industrial controllers and automotive ECUs.

Typical Applications

• Industrial Automation Controllers - This DDR2 SDRAM serves as main memory in programmable logic controllers and distributed control systems where the extended temperature rating ensures continuous operation in factory environments with variable climate control.
• Automotive Infotainment Systems - Provides frame buffer and program memory for in-vehicle displays and navigation units that must function reliably across extreme cabin temperatures from cold winter startups to summer heat exposure.
• Outdoor Telecommunications Equipment - Enables reliable data buffering in cellular base stations, wireless access points, and fiber optic network equipment mounted in outdoor cabinets subject to direct sun exposure and sub-zero winter conditions.
• Medical Diagnostic Instruments - Supports real-time image processing and data acquisition in portable ultrasound devices and patient monitors that operate in varied clinical environments from emergency vehicles to operating rooms.
• Industrial Machine Vision Systems - Serves as high-speed image buffer memory in factory inspection cameras and robotic guidance systems where extended temperature tolerance accommodates proximity to heat-generating manufacturing processes.

Unique Advantages

• Simplified Thermal Management: Extended 105°C maximum ambient rating eliminates the need for active cooling in sealed industrial enclosures, reducing system complexity and maintenance requirements.
• Design Longevity: Active lifecycle status from ISSI ensures ongoing availability for long product lifecycles typical in industrial and automotive platforms with 10+ year production runs.
• Proven DDR2 Ecosystem: Mature DDR2 SDRAM technology benefits from established controller IP, reference designs, and validation tools, accelerating time-to-market for new industrial designs.
• Reduced BOM Cost: Parallel interface eliminates the need for additional level shifters or interface converters when connecting directly to legacy microcontrollers and DSPs with native parallel memory buses.
• Enhanced Reliability in Variable Environments: Wide operating temperature qualification reduces field failure rates in equipment exposed to daily thermal cycling and seasonal temperature extremes.
• Space-Efficient Integration: Small-footprint TWBGA package enables high-density memory subsystems in compact industrial computers and automotive modules with strict size constraints.
