AS4C16M16D1-5TINTR

The AS4C16M16D1-5TINTR is a 256-megabit synchronous dynamic random access memory (SDRAM) module utilizing DDR (Double Data Rate) technology. Organized as 16M x 16, this volatile memory device operates at a 200MHz clock frequency with a 7ns access time, making it well-suited for applications requiring fast data transfer rates. Housed in a 66-pin TSOP II package, it offers reliable memory expansion for embedded systems and industrial equipment.

Key Features

• Memory Architecture - 256Mb total capacity organized as 16M x 16, providing flexible integration for 16-bit data bus systems.
• DDR SDRAM Technology - Double data rate operation transfers data on both rising and falling clock edges, effectively doubling throughput compared to standard SDRAM at the same clock frequency.
• Performance Specifications - 200MHz clock frequency with 7ns access time and 15ns write cycle time ensures responsive memory performance for time-sensitive applications.
• Power Supply - Operates on 2.3V to 2.7V supply voltage, compatible with low-power embedded designs.
• Industrial Temperature Range - Rated for operation from -40°C to 85°C, supporting deployment in harsh environmental conditions.
• Package Format - 66-pin TSOP II (0.400", 10.16mm width) package provides a compact footprint for space-constrained PCB layouts.

Typical Applications

• Industrial Control Systems - This DDR SDRAM provides working memory for programmable logic controllers (PLCs) and distributed control systems where the extended temperature rating ensures reliable operation in factory floor and outdoor industrial environments.
• Embedded Computing - Serves as main memory for embedded processors and microcontrollers in applications such as point-of-sale terminals, kiosks, and data acquisition systems that require fast volatile storage for program execution and data buffering.
• Communications Equipment - Supports network routers, switches, and telecommunications infrastructure where the parallel interface and DDR performance facilitate packet buffering and routing table management.
• Test and Measurement Instruments - Provides data capture and processing memory for oscilloscopes, logic analyzers, and automated test equipment that require high-speed temporary storage during measurement cycles.

Unique Advantages

• Extended Temperature Tolerance: The -40°C to 85°C operating range reduces the need for additional thermal management components in industrial designs, simplifying system architecture and lowering BOM costs.
• Proven DDR Technology: DDR SDRAM offers a mature, well-understood memory architecture with broad ecosystem support, reducing integration risk and development time compared to newer memory technologies.
• Standard Parallel Interface: The parallel memory interface eliminates the need for complex serial controllers, simplifying firmware development and reducing latency for direct memory access applications.
• Compact TSOP II Package: The narrow 10.16mm width package optimizes board space utilization in space-constrained designs while maintaining compatibility with standard SMT assembly processes.
• Flexible Memory Organization: The 16M x 16 configuration aligns naturally with 16-bit microcontroller and processor architectures, minimizing address decoding complexity and improving memory access efficiency.
