Overview of IS45S32400B-7BLA1-TR - 128Mbit Parallel SDRAM
The IS45S32400B-7BLA1-TR is a 128Mbit synchronous dynamic random access memory (SDRAM) device organized as 4M x 32 bits. This parallel interface DRAM operates from a 3V to 3.6V supply and supports clock frequencies up to 143MHz with 5.4ns access time. Designed for applications requiring reliable memory performance across industrial temperature ranges, this SDRAM provides cost-effective volatile memory storage in a compact 90-TFBGA package.
Key Features
- Memory Architecture - 128Mbit density organized as 4M x 32, providing straightforward integration for systems requiring 32-bit parallel data paths with moderate density requirements.
- Performance Specifications - Operates at clock frequencies up to 143MHz with 5.4ns access time, delivering responsive memory performance for real-time data processing and buffering applications.
- Power Supply - Single 3.3V supply operation (3V to 3.6V range) simplifies power distribution and reduces component count in embedded system designs.
- Industrial Temperature Range - Qualified for -40°C to 85°C ambient operation, ensuring consistent performance in harsh environmental conditions typical of industrial, automotive, and outdoor installations.
- Package - 90-pin TFBGA (8x13mm) offers a compact footprint for space-constrained designs while maintaining the parallel interface bandwidth advantages.
Typical Applications
- Industrial Control Systems - This SDRAM serves as working memory for programmable logic controllers (PLCs) and human-machine interfaces (HMIs) where the extended temperature range ensures reliable operation in factory floor environments subject to temperature variations.
- Automotive Electronics - Provides memory buffering for infotainment systems, instrument clusters, and body control modules where the industrial temperature qualification supports under-hood and cabin applications with wide thermal swings.
- Test and Measurement Equipment - Functions as data acquisition buffer memory in oscilloscopes, spectrum analyzers, and data loggers where the 32-bit parallel interface enables efficient high-speed data capture and transfer.
- Networking Equipment - Offers packet buffering and routing table storage in switches, routers, and gateways deployed in industrial networking environments where extended temperature operation is required.
- Medical Devices - Supports embedded processing in diagnostic equipment and patient monitoring systems where the industrial temperature range accommodates diverse installation environments from climate-controlled facilities to portable field units.
Unique Advantages
- Proven SDRAM Technology: Leverages mature synchronous DRAM architecture with established driver support and broad compatibility across microprocessor and FPGA platforms, reducing development risk and time-to-market.
- Extended Temperature Operation: The -40°C to 85°C qualification eliminates the need for thermal management in many industrial applications, reducing system complexity and cost.
- Parallel Interface Bandwidth: The 32-bit parallel data path delivers deterministic access latency without the protocol overhead of serial interfaces, simplifying timing analysis for real-time systems.
- Compact BGA Footprint: The 8x13mm TFBGA package minimizes board space requirements while the ball grid array construction improves signal integrity compared to equivalent QFP packages.
- Standard 3.3V Operation: Compatibility with common 3.3V logic families and microcontrollers simplifies level translation requirements and reduces interface component count.
- Cost-Effective Density: The 128Mbit capacity addresses mid-range memory requirements without over-provisioning, optimizing bill-of-materials cost for applications with defined memory needs.
