AS4C32M16D1A-5TIN

The AS4C32M16D1A-5TIN is a 512Mbit DDR SDRAM from Alliance Memory featuring a 32M x 16 memory organization. This parallel interface memory device operates at clock frequencies up to 200MHz and delivers fast 0.7ns access times, making it well-suited for embedded systems and industrial applications requiring reliable volatile memory storage.

Designed for operation across an extended temperature range of -40°C to 85°C, this SDRAM provides consistent performance in demanding environments where standard commercial-grade components may not suffice.

Key Features

• Memory Capacity and Organization - 512Mbit total capacity organized as 32M x 16, providing efficient word-width access for 16-bit data bus architectures.
• DDR SDRAM Technology - Double data rate architecture transfers data on both clock edges, effectively doubling throughput compared to single data rate SDRAM at the same clock frequency.
• High-Speed Operation - 200MHz clock frequency with 0.7ns access time and 15ns write cycle time enables responsive memory transactions for performance-sensitive applications.
• Extended Temperature Range - Operates reliably from -40°C to 85°C (TA), supporting deployment in industrial and outdoor environments with wide ambient temperature variations.
• Low Voltage Operation - 2.3V to 2.7V supply voltage range reduces power consumption and provides compatibility with low-power system designs.
• Industry-Standard Package - 66-TSOP II package (0.400", 10.16mm width) offers a proven form factor with established PCB footprints and second-sourcing options.

Typical Applications

• Industrial Control Systems - This DDR SDRAM serves as program and data memory in PLCs, motor drives, and process controllers where the extended temperature range ensures reliable operation in factory floor environments.
• Embedded Computing - The 32M x 16 organization and parallel interface integrate efficiently with embedded processors and FPGAs requiring external memory expansion for buffering, caching, or code execution.
• Networking Equipment - Routers, switches, and access points utilize this SDRAM for packet buffering and routing table storage, benefiting from the 200MHz clock speed for high-throughput data handling.
• Medical Devices - Patient monitoring systems and diagnostic equipment leverage the industrial temperature rating and consistent availability for designs requiring long product lifecycles.
• Test and Measurement - Data acquisition systems and instrumentation use this memory for sample buffering where fast write cycles and reliable operation across temperature extremes are essential.

Unique Advantages

• Long-Term Availability: Alliance Memory specializes in providing memory products with extended lifecycle support, reducing redesign risk for applications with multi-year production requirements.
• Drop-In Compatibility: Pin-compatible with industry-standard DDR SDRAM devices, simplifying second-sourcing strategies and minimizing qualification effort for existing designs.
