AS4C4M32D1A-5BINTR

The AS4C4M32D1A-5BINTR is a 128Mbit DDR SDRAM memory device from Alliance Memory, Inc., organized as 4M x 32 with a parallel interface. Built on proven DDR SDRAM technology, this memory component delivers reliable performance for embedded systems requiring fast, volatile memory storage. With a 200MHz clock frequency and -40°C to 85°C operating temperature range, it addresses the needs of industrial, communication, and computing applications where extended temperature tolerance is essential.

Key Features

• Memory Architecture - 128Mbit capacity organized as 4M x 32, providing flexible data width for 32-bit bus systems and efficient memory access patterns.
• DDR SDRAM Technology - Double data rate operation at 200MHz clock frequency with 7ns access time enables high-bandwidth data transfers while maintaining compatibility with standard DDR controllers.
• Power Supply - 2.3V to 2.7V operating voltage range supports low-power designs and compatibility with modern embedded processors.
• Industrial Temperature Range - -40°C to 85°C operating temperature ensures reliable operation in harsh environmental conditions beyond consumer-grade specifications.
• Package - 144-LFBGA in 12mm x 12mm footprint provides compact board-level integration with good thermal characteristics.

Typical Applications

• Industrial Control Systems - This DDR SDRAM provides working memory for programmable logic controllers (PLCs) and distributed control systems where the extended temperature range ensures stable operation in factory floor environments with temperature extremes.
• Network Infrastructure - The parallel interface and 200MHz operation support buffering and data processing in routers, switches, and telecom equipment where consistent performance across temperature variations is critical for 24/7 uptime.
• Embedded Computing - Serves as main system memory in embedded processors and single-board computers operating in industrial or outdoor installations where ambient temperature fluctuations require components rated beyond commercial grades.
• Automotive Infotainment - The -40°C to 85°C temperature tolerance makes this memory suitable for non-critical automotive applications such as dashboard displays and entertainment systems that experience cabin temperature variations.
• Test and Measurement Equipment - Provides data acquisition buffering and waveform storage in portable instruments that may be used in field conditions requiring industrial temperature resilience.

Unique Advantages

• Extended Temperature Reliability: The -40°C to 85°C operating range eliminates the need for thermal management systems in many industrial applications, reducing BOM costs and design complexity.
• Standard DDR Interface: Full compatibility with industry-standard DDR SDRAM controllers simplifies integration into existing designs and reduces development risk.
• Proven Technology: DDR SDRAM's mature ecosystem provides well-understood timing characteristics and broad software support, accelerating time-to-market.
• Balanced Performance: The 200MHz clock frequency and 7ns access time deliver sufficient bandwidth for industrial control and embedded applications without the power consumption and signal integrity challenges of higher-speed memory technologies.
• Compact Footprint: The 12mm x 12mm LFBGA package maximizes board space efficiency in space-constrained embedded designs.
• Active Lifecycle Status: Current production availability supports long-term product planning and reduces obsolescence risk for industrial equipment with extended lifecycles.
