• Performance Specifications - 5.4ns access time with 143MHz maximum clock frequency enables responsive data throughput for real-time control and data buffering applications.
• Power Supply - 3V to 3.6V operating voltage aligns with standard 3.3V logic levels, simplifying integration into existing digital designs.
• Parallel Interface - Traditional parallel bus connection provides straightforward integration with microcontrollers, DSPs, and FPGAs supporting standard SDRAM protocols.
• Extended Temperature Range - Industrial-grade -40°C to 85°C operating range ensures stable operation in harsh environments where temperature extremes are common.
• Package Format - 54-pin TSOP II package in 10.16mm width offers compact footprint for space-constrained PCB layouts.

Typical Applications

• Industrial Control Systems - This SDRAM provides working memory for programmable logic controllers (PLCs) and industrial computers where extended temperature tolerance ensures reliable operation in factory floor environments subject to thermal stress.
• Communications Equipment - The 64Mbit capacity serves as packet buffering memory in routers, switches, and telecommunications infrastructure where moderate-density volatile storage handles transient data flows.
• Embedded Computing - This memory supports program execution and data storage in embedded processors and microcontroller systems where synchronous operation and 16-bit data width match common embedded architectures.
• Test and Measurement Instruments - The parallel interface and industrial temperature range make this SDRAM suitable for data acquisition systems and bench equipment that must operate reliably across varying environmental conditions.

Unique Advantages

• Proven SDRAM Architecture: Standard synchronous DRAM protocol ensures broad compatibility with existing controller IP and simplifies firmware development using established memory timing specifications.
• Industrial Temperature Capability: Extended -40°C to 85°C rating eliminates the need for thermal management in many industrial installations, reducing system complexity and cost.
• 16-Bit Data Width: Native 16-bit organization matches word sizes of many embedded processors and DSPs, eliminating the need for byte-to-word conversion logic and simplifying memory controller design.
• Moderate Density: 64Mbit capacity provides sufficient buffer and working memory for many embedded applications without the cost premium of higher-density alternatives.
• Standard 3.3V Operation: Compatibility with widely-used 3.3V logic levels avoids the need for level shifters and supports direct connection to common microcontrollers and FPGAs.
• Compact TSOP II Package: Industry-standard surface-mount package enables automated assembly and fits within tight board space constraints typical of embedded products.
