71321LA55TF

Memory IC Overview

The Renesas Electronics Corporation 71321LA55TF is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2048 words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is designed for industrial temperature ranges.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate systems
• Asynchronous parallel interface supporting standard logic levels
• Volatile memory technology retaining data only during active power supply

Memory IC Applications

• High-speed data buffering between processing units
• Cache memory implementation in embedded systems
• Data storage in telecommunications equipment

Memory IC Procurement Notes

Verify the specific suffix configuration against current manufacturer documentation to ensure compatibility with required environmental ratings and package dimensions. Confirm RoHS compliance status as legacy variants may differ. Check for obsolescence notices or recommended replacement parts before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without bus contention. Ensure the system design accommodates the 55-nanosecond access speed and 64-pin TQFP footprint. Validate that the operating voltage and temperature range align with the target application environment.

Memory IC Part Context

This part belongs to the 71321LA series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to suit different performance requirements. The LA designation typically indicates lead-free and halogen-free compliant versions compared to older SA series counterparts.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Verify pinout compatibility and electrical specifications before substituting.
