Device Structure

Dual port architecture allows simultaneous access from two independent buses. Each port operates asynchronously, supporting separate data flows without coordination. Internal memory cell array stores 16Kbit in 2K x 8 organization. Layout optimized for parallel data transfer.

Performance Characteristics

Fast memory access with 35 ns access and write times. Reliable operation in standard commercial temperature range. Dual port design enables simultaneous read and write operations. Stable performance at 4.5V to 5.5V supply. Parallel interface maximizes throughput for high-speed applications.

Application Environments

Used in embedded systems, communications equipment, industrial controllers, and hardware requiring rapid memory access and multitasking. Suitable for legacy products continuing support of 5V components, or specialized multi-master applications.

Selection Guidelines

Choose when dual port, asynchronous parallel SRAM is required. Verify system supply voltage matches 4.5V to 5.5V. Confirm operating temperature needs do not exceed 0°C to 70°C. Check that PLCC packaging fits PCB layout and reflow process. Consider RoHS status if environmental compliance is needed, as this model is not RoHS compliant.

Usage Considerations

Obsolete product status may restrict availability. Handle MSL Level 3 packaging within 168 hours of opening to avoid moisture damage. Ensure compatibility with 5V logic levels. Use anti-static precautions during assembly. Non-compliant with RoHS regulations, so avoid in new designs targeting compliance. Confirm replacement options before design-in.
