IS42S32400J-7BLI

The IS42S32400J-7BLI is a 128Mbit synchronous dynamic random access memory (SDRAM) organized as 4M x 32 bits, designed for high-performance embedded systems requiring fast, reliable volatile memory. Operating at clock frequencies up to 143MHz with a 5.4ns access time, this LVTTL-compatible SDRAM delivers responsive data throughput for processor-intensive applications. Its extended industrial temperature range of -40°C to 85°C makes it well-suited for demanding environments where standard commercial-grade memory may not perform reliably.

Key Features

• Memory Architecture - 128Mbit capacity organized as 4M x 32-bit configuration provides flexible data word width for 32-bit processors and controllers.
• High-Speed Performance - 143MHz clock frequency and 5.4ns access time enable rapid data transfers for time-sensitive operations.
• LVTTL Interface - Low-voltage TTL-compatible interface simplifies integration with standard logic families and reduces power consumption.
• Extended Temperature Range - -40°C to 85°C operation ensures stable performance across industrial temperature extremes.
• Compact Package - 90-ball TFBGA (8mm x 13mm) footprint minimizes board space requirements for space-constrained designs.
• Standard Voltage Supply - 3V to 3.6V supply voltage aligns with common system power rails for simplified power design.

Typical Applications

• Industrial Control Systems - Provides working memory for programmable logic controllers (PLCs) and distributed control systems where the extended temperature range ensures reliable operation in factory floor environments.
• Embedded Computing - Serves as main memory for ARM, MIPS, or other 32-bit embedded processors in applications requiring fast random access to program code and data structures.
• Telecommunications Equipment - Supports packet buffering and data processing in network switches, routers, and base stations where the 143MHz clock frequency maintains throughput under load.
• Test and Measurement Instruments - Functions as acquisition memory in oscilloscopes, logic analyzers, and data loggers where fast access time enables real-time data capture and display.
• Medical Devices - Provides volatile data storage for diagnostic imaging equipment and patient monitoring systems operating in controlled industrial temperature environments.

Unique Advantages

• Wide Temperature Tolerance: -40°C to 85°C operation eliminates the need for thermal management in many industrial applications, reducing system complexity and cost.
• Board Space Efficiency: The compact 90-TFBGA package reduces PCB footprint by approximately 40% compared to equivalent TSOP packages, enabling denser board layouts.
• Standard Interface Compatibility: LVTTL signaling ensures direct connectivity to a wide range of processors and controllers without level translation circuitry.
• 32-Bit Data Bus: Native 32-bit organization matches common embedded processor architectures, minimizing memory access overhead and simplifying hardware design.
• Proven SDRAM Technology: Synchronous operation with the system clock simplifies timing design and provides predictable performance compared to asynchronous DRAM alternatives.
• Active Lifecycle Status: Current production availability supports long-term design commitments and reduces obsolescence risk for industrial product lifecycles.
