IS42S32800J-6BL

The IS42S32800J-6BL is a 256-megabit synchronous dynamic random access memory (SDRAM) organized as 8M x 32 bits. This high-performance parallel SDRAM operates at clock frequencies up to 166 MHz with a 5.4 ns access time, making it ideal for applications requiring fast, reliable volatile memory in a compact 90-TFBGA package.

Designed for commercial temperature operation from 0°C to 70°C, this SDRAM solution provides efficient memory bandwidth for embedded systems, consumer electronics, and industrial equipment where moderate speed and density requirements are balanced with cost considerations.

Key Features

• Memory Organization - 8M x 32-bit architecture provides 256 megabits of volatile memory storage, offering a practical balance between density and data width for 32-bit processor interfaces.
• Performance Specifications - 166 MHz clock frequency with 5.4 ns access time delivers responsive data throughput for real-time processing applications without requiring high-speed DDR technology.
• Parallel Interface - Standard SDRAM parallel interface simplifies integration with legacy and cost-optimized designs using established controller architectures.
• Power Requirements - Operates from 3V to 3.6V supply voltage, compatible with common 3.3V system rails found in embedded and consumer electronics.
• Package Format - 90-ball TFBGA (8mm x 13mm) provides a compact footprint for space-constrained PCB layouts while maintaining reliable solder joint connections.
• Operating Temperature Range - Commercial temperature grade (0°C to 70°C) supports typical indoor and consumer application environments.

Typical Applications

• Consumer Electronics - This SDRAM serves as main memory in set-top boxes, digital cameras, and portable media players where the 32-bit wide data path efficiently supports video buffering and user interface operations at moderate clock speeds.
• Embedded Systems - The parallel SDRAM interface integrates directly with 32-bit microprocessors and microcontrollers in point-of-sale terminals, kiosks, and control panels where proven SDRAM technology reduces design risk.
• Networking Equipment - Provides packet buffering and routing table memory in routers, switches, and gateways where the 256Mbit capacity handles moderate traffic loads at commercial temperature ratings.
• Industrial Control - Functions as working memory in PLCs, motor drives, and monitoring systems operating in controlled environments within the 0°C to 70°C temperature specification.
• Medical Devices - Supports data acquisition and processing in diagnostic equipment and patient monitoring systems where the stable parallel interface ensures reliable operation in clinical settings.

Unique Advantages
