IS42S16400J-6TLI-TR

The IS42S16400J-6TLI-TR is a 64-megabit synchronous DRAM (SDRAM) organized as 4M x 16 bits, designed for systems requiring fast, reliable volatile memory. Operating at up to 166MHz with a 5.4ns access time, this parallel-interface SDRAM provides cost-effective memory expansion for industrial, commercial, and embedded applications. With an extended temperature range of -40°C to 85°C, it delivers consistent performance in demanding environments where standard-grade memory may not be suitable.

Key Features

• Memory Architecture - 64-megabit capacity organized as 4M x 16, providing flexible data bus integration for 16-bit systems.
• High-Speed Performance - 166MHz clock frequency with 5.4ns access time enables rapid data retrieval for time-sensitive applications.
• Parallel Interface - Standard SDRAM parallel interface simplifies integration with processors, FPGAs, and ASICs that support legacy memory architectures.
• Extended Temperature Range - -40°C to 85°C operating range ensures reliable operation in industrial, automotive, and outdoor environments.
• Low Voltage Operation - 3V to 3.6V supply voltage reduces power consumption while maintaining compatibility with standard logic levels.
• Compact Package - 54-pin TSOP II package (10.16mm width) offers high density for space-constrained PCB designs.

Typical Applications

• Industrial Control Systems - This SDRAM provides working memory for PLCs, industrial PCs, and distributed control systems where the extended temperature range ensures reliable operation in factory floor environments subject to temperature extremes.
• Embedded Computing Platforms - The parallel interface and moderate capacity make this memory ideal for legacy embedded systems, single-board computers, and real-time operating systems that require fast data access without the complexity of DDR technologies.
• Test and Measurement Equipment - High-speed access times support data buffering in oscilloscopes, logic analyzers, and data acquisition systems where rapid capture and temporary storage of measurement data is critical.
• Communications Infrastructure - This SDRAM serves as buffer memory in routers, switches, and base station equipment operating in challenging thermal environments, providing reliable data handling for packet processing and protocol management.
• Legacy System Upgrades - The TSOP II package and standard SDRAM pinout enable direct replacement or capacity upgrades in existing designs that were originally specified with similar parallel SDRAM components.

Unique Advantages

• Extended Temperature Tolerance: The -40°C to 85°C range eliminates the need for additional thermal management in industrial designs, reducing system complexity and improving reliability in harsh environments.
• Proven SDRAM Technology: Mature, well-understood parallel SDRAM architecture reduces design risk and simplifies firmware development compared to newer DDR technologies, particularly for legacy system support.
• Simplified BOM Management: Standard SDRAM interface requires fewer support components and simpler routing compared to high-speed DDR interfaces, reducing PCB layer count and design costs.
• Drop-in Compatibility: Industry-standard TSOP II footprint and pinout enable easy sourcing alternatives and design migration, protecting against single-source supply chain risks.
• Power-Efficient Operation: 3V to 3.6V operation aligns with modern low-power system designs while maintaining compatibility with 3.3V logic families commonly used in industrial electronics.
• Cost-Effective Capacity: 64-megabit density provides sufficient working memory for many embedded applications without over-provisioning, optimizing cost per bit for budget-conscious designs.
