Device Structure

Built with dual-port architecture allowing two independent ports to access the memory at the same time without interference. Uses parallel interface for rapid data transfer. Each port has its own control and address lines, allowing concurrent read and write operations. Supplied in a compact 64-TQFP package for space-efficient surface mounting.

Performance Characteristics

Very fast data access and write cycles (55 ns), enabling high-speed data exchange between systems. Asynchronous operation means it does not require a clock signal, providing flexibility in timing. High data integrity between two accessing ports. Reliable within the 0°C to 70°C temperature range. Operates at 5V logic, typical for older system architectures.

Application Environments

Ideal for use in communication equipment, networking devices, dual-processor systems, shared memory buffers, and situations requiring quick data exchange between two controllers or systems. Commonly used in legacy systems or where dual access to static RAM is necessary. Suitable for surface mount assemblies in controlled environments.

Selection Guidelines

Choose this product when dual data access and fast parallel SRAM operation is needed. Confirm compatibility with 5V supply voltage and legacy logic levels. Ensure the space requirements match the TQFP 64-pin package. Check environmental requirements against product’s operation temperature and MSL rating. Because this model is obsolete, confirm availability for long-term applications or consider alternative/newer parts.

Usage Considerations

Obsolete status – consider long-term availability and life-cycle planning. Not RoHS compliant; unsuitable for new designs requiring lead-free compliance. Follow MSL level precautions during storage and soldering (Level 3, 168 hours out-of-bag at ≤30°C/60% RH). Careful signal timing and interfacing is required for proper asynchronous operation and to avoid bus contention. Operates only in the 0°C to 70°C temperature range.
