71321LA25TFI

Memory IC Overview

The 71321LA25TFI is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 16 kilobits organized as 2K x 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 10x10 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate processors or systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control networks

Memory IC Procurement Notes

Verify the exact suffix configuration, as the provided model lacks the standard trailing characters found in official datasheets. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the supplier provides valid traceability documentation for this specific package variant.

Memory IC Selection Notes

Select this component when a 25ns access speed is required for dual-port applications within a 5V logic environment. Compare against the 71321SA series for pin-compatible alternatives if different timing specifications are needed. Verify that the 64-TQFP footprint matches the target PCB design constraints.

Memory IC Part Context

This part belongs to the 71321 family of high-speed CMOS dual-port SRAMs. The 'LA' designation typically indicates a specific voltage and speed grade within the Renesas memory portfolio. These components are designed for applications requiring high bandwidth and low latency between multiple masters.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-references. Potential substitutes may include other members of the 71321 series with compatible pinouts and electrical characteristics.
