Overview of AS4C4M32D1-5BIN - 128Mbit DDR SDRAM with Industrial Temperature Range
The AS4C4M32D1-5BIN is a 128-megabit DDR SDRAM organized as 4M x 32, delivering fast synchronous memory performance in a compact 144-LFBGA package. Engineered for industrial applications requiring reliable data storage and retrieval, this parallel interface memory solution operates across an extended temperature range of -40°C to 85°C, making it well-suited for systems deployed in challenging environmental conditions.
With a 200MHz clock frequency and 7ns access time, this DDR SDRAM provides the bandwidth needed for data-intensive embedded applications while maintaining a low-power operating voltage of 2.3V to 2.7V. The 4M x 32 organization offers flexible memory architecture options for system designers.
Key Features
- Memory Architecture - 128Mbit capacity organized as 4M x 32, providing a 32-bit data path that enables efficient data transfer for parallel processing applications.
- DDR SDRAM Technology - Double data rate synchronous DRAM delivers data on both rising and falling clock edges, doubling the effective bandwidth compared to single data rate SDRAM at the same clock frequency.
- High-Speed Performance - 200MHz clock frequency with 7ns access time and 12ns write cycle time ensures rapid data access for time-critical operations.
- Industrial Temperature Rating - Operates reliably across -40°C to 85°C ambient temperature range, suitable for industrial control systems and automotive infotainment applications.
- Low-Voltage Operation - 2.3V to 2.7V supply voltage reduces power consumption and heat generation in space-constrained designs.
- Compact LFBGA Package - 144-pin low-profile fine-pitch BGA in a 12mm x 12mm footprint enables high-density board layouts for space-constrained applications.
Typical Applications
- Industrial Control Systems - This DDR SDRAM provides the fast, reliable memory needed for programmable logic controllers (PLCs) and distributed control systems where extended temperature tolerance ensures stable operation in factory floor environments.
- Networking Equipment - The 32-bit parallel interface and 200MHz operation support packet buffering and routing table storage in switches and routers operating in temperature-variable telecom closets and outdoor enclosures.
- Automotive Infotainment - The industrial temperature range makes this memory suitable for in-vehicle entertainment and navigation systems that must function reliably from cold starts to high cabin temperatures.
- Medical Instrumentation - Provides stable memory performance for diagnostic equipment and patient monitoring systems where data integrity and environmental resilience are critical requirements.
- Embedded Computing - Serves as main system memory for industrial single-board computers and embedded controllers requiring balance between performance, power efficiency, and temperature tolerance.
Unique Advantages
- Extended Temperature Reliability: The -40°C to 85°C operating range eliminates the need for additional thermal management in many industrial deployments, reducing system complexity and cost.
- Efficient 32-Bit Data Path: The 4M x 32 organization provides a wide data bus that reduces the number of memory devices needed for 32-bit processor architectures, simplifying board layout and reducing BOM costs.
- Proven DDR Technology: DDR SDRAM offers a mature, well-understood architecture with broad industry support and established design practices, reducing development risk compared to newer memory technologies.
- Low Operating Voltage: The 2.3V to 2.7V supply voltage reduces power consumption and allows compatibility with a wide range of industrial processors and controllers.
- Compact Footprint: The 12mm x 12mm LFBGA package provides high pin density while maintaining a small board footprint, critical for space-constrained industrial and embedded designs.
- Standard Parallel Interface: The parallel DDR interface provides straightforward integration with legacy processors and controllers without requiring complex serial protocol implementations.
