Overview of IS42S16400N-7BLI-TR - 64Mbit Synchronous DRAM in Compact TFBGA Package
The IS42S16400N-7BLI-TR is a 64-megabit synchronous dynamic RAM optimized for space-constrained embedded systems and industrial applications. Featuring a 4M x 16 memory organization and SDRAM technology, this component delivers reliable parallel data storage with a 143MHz clock frequency and 5.4ns access time. The 54-pin TFBGA package measures just 8x8mm, making it ideal for applications where board space is at a premium while extended temperature tolerance ensures operation across industrial environments.
Key Features
- Memory Core: 64-megabit capacity organized as 4M x 16, providing efficient 16-bit wide data paths for parallel processing applications.
- High-Speed Performance: 143MHz clock frequency with 5.4ns access time enables responsive data operations for real-time systems and embedded controllers.
- Standard Interface: LVTTL-compatible memory interface simplifies integration with common microcontrollers and processors without level-shifting requirements.
- Power Supply: Operates on standard 3V to 3.6V supply voltage, compatible with most 3.3V system designs.
- Compact Package: 54-pin TFBGA in an 8x8mm footprint maximizes board space efficiency for portable and embedded designs.
- Extended Temperature Range: -40°C to 85°C operating temperature supports reliable operation in industrial and automotive environments.
Typical Applications
- Industrial Control Systems: This SDRAM provides working memory for programmable logic controllers and human-machine interfaces where the extended temperature range ensures reliable operation in factory floor conditions and the compact package fits space-limited control panel designs.
- Embedded Computing: The 16-bit wide data path and 143MHz clock frequency support real-time data buffering in embedded systems such as data loggers, measurement instruments, and communication gateways where moderate memory capacity meets application requirements.
- Portable Instrumentation: The small 8x8mm TFBGA footprint and 3.3V operation enable battery-powered test equipment and handheld devices to integrate sufficient volatile memory without sacrificing portability or power efficiency.
- Networking Equipment: Serves as packet buffer memory in switches, routers, and network appliances where synchronous operation aligns with system clocking and the industrial temperature rating supports installation in telecom closets and outdoor enclosures.
- Point-of-Sale Terminals: Provides system memory for retail terminals and kiosks operating in diverse environmental conditions, with the compact package supporting slim form factors and the extended temperature range accommodating installation in uncontrolled environments.
Unique Advantages
- Simplified Board Layout: The compact 8x8mm TFBGA package reduces PCB area requirements, allowing designers to minimize board size or allocate space for additional features.
- Single-Supply Operation: Standard 3.3V supply voltage eliminates the need for multiple power rails, simplifying power distribution and reducing BOM complexity.
- Industrial Temperature Tolerance: -40°C to 85°C range extends deployment options beyond commercial environments, reducing the need for separate industrial-grade product variants.
- Standard SDRAM Interface: LVTTL-compatible signaling ensures broad compatibility with existing processor ecosystems and simplifies migration from other SDRAM devices.
- Active Lifecycle Status: Current production availability supports long-term product roadmaps and reduces supply chain risk for designs with extended lifecycles.
- Established Technology: SDRAM architecture is well-understood and widely supported by development tools, reducing design risk and accelerating time-to-market.
