IS42S32800J-75EBL-TR

The IS42S32800J-75EBL-TR is a 256-Mbit synchronous dynamic random access memory (SDRAM) designed for commercial applications requiring high-speed data access and moderate density. Built on proven SDRAM technology, this device features an 8M x 32 memory organization that provides efficient 32-bit parallel data transfer. Operating at clock frequencies up to 133MHz with a 6ns access time, this SDRAM is ideal for systems requiring reliable temporary data storage with fast read/write performance in consumer electronics, networking equipment, and embedded computing platforms.

The device operates from a standard 3.0V to 3.6V power supply and functions within a commercial temperature range of 0°C to 70°C, making it suitable for office and indoor environments where environmental conditions are controlled.

Key Features

• Memory Architecture - 256-Mbit capacity organized as 8M x 32, providing 32-bit wide data access for applications requiring parallel data transfer and higher bandwidth than x8 or x16 configurations.
• High-Speed Operation - 133MHz clock frequency with 6ns access time delivers responsive data throughput for time-sensitive applications including network buffers, graphics processing, and real-time data acquisition systems.
• Parallel Interface - 32-bit parallel data bus enables simultaneous transfer of four bytes per clock cycle, reducing transaction overhead and improving system efficiency compared to narrower interfaces.
• Standard Voltage Operation - 3.0V to 3.6V supply voltage matches common system power rails, simplifying power supply design and reducing component count in embedded systems.
• Commercial Temperature Range - Operates reliably from 0°C to 70°C, suitable for indoor commercial applications including office equipment, point-of-sale systems, and consumer devices.
• Compact Package - 90-pin TFBGA (8mm x 13mm) footprint provides high pin density in a space-efficient form factor, enabling compact PCB layouts in size-constrained designs.

Typical Applications

• Networking Equipment - Serves as packet buffer memory in routers and switches where the 32-bit interface supports high-speed data queuing and the moderate capacity handles typical packet buffering requirements in enterprise networking gear.
• Set-Top Boxes and Media Devices - Provides working memory for video decoding and interface rendering where the parallel architecture supports frame buffer operations and the commercial temperature range suits indoor consumer electronics.
• Embedded Computing Platforms - Functions as main system RAM in embedded controllers and single-board computers where 256Mbit capacity is sufficient for operating system and application data while the 133MHz speed matches typical embedded processor bus speeds.
• Point-of-Sale Terminals - Offers reliable temporary storage for transaction processing and display management in retail environments where the commercial temperature rating aligns with indoor operation and the compact package fits space-limited terminal designs.
• Test and Measurement Instruments - Supports data acquisition buffering in benchtop instruments where the parallel interface enables rapid sample storage and the standard voltage operation simplifies integration with common instrument architectures.

Unique Advantages

• Optimized 32-bit Architecture: The x32 organization delivers four times the per-cycle throughput of x8 configurations, reducing memory transaction overhead and improving system responsiveness in bandwidth-sensitive applications.
• Proven SDRAM Technology: Leverages mature synchronous DRAM architecture with broad ecosystem support, ensuring compatibility with existing memory controllers and reducing integration risk compared to newer memory types.
• Standard Supply Voltage: 3.0V to 3.6V operation eliminates the need for dedicated voltage regulators in many systems, reducing BOM cost and board complexity.
• Space-Efficient Packaging: The 90-TFBGA package concentrates 32 data pins plus control signals into an 8mm x 13mm footprint, freeing valuable PCB real estate for other components.
• Active Lifecycle Status: Current production availability ensures long-term supply stability for multi-year product designs, reducing obsolescence risk and supporting ongoing production requirements.
• Cost-Effective Density: 256Mbit capacity provides sufficient memory for many embedded applications at a lower cost point than higher-density devices, optimizing system cost without over-provisioning.

Why Choose IS42S32800J-75EBL-TR?

This SDRAM is positioned for commercial embedded systems where designers need proven memory technology with a 32-bit interface and moderate density. The device's 133MHz operation and 6ns access time align well with embedded processors in the 100-200MHz range, while the 256Mbit capacity suits applications that require more than basic SRAM can provide but don't justify higher-density DRAM solutions. The commercial temperature rating makes it appropriate for indoor equipment designs.

For systems requiring reliable, cost-effective working memory with a parallel interface, this SDRAM offers a balance of performance, density, and package size that simplifies design while meeting the operational requirements of networking, consumer electronics, and embedded computing applications.
