71421LA35PF

Overview

The Renesas Electronics Corporation 71421LA35PF is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 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, functioning between 0°C and 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Applications

• High-speed data buffering in communication equipment.

Procurement Notes

Verify the exact package marking and manufacturer date code against official Renesas documentation before integration. Confirm that the 35ns speed grade matches system timing requirements. Ensure the 4.5V to 5.5V power supply rails are stable within specified tolerances. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate pin compatibility with existing PCB footprints.

Selection Notes

Select this component when a design requires independent read/write ports for concurrent data handling without bus contention. The 16Kb density suits applications needing moderate buffer space. Verify that the 64-TQFP package fits the available board real estate. Ensure the operating temperature range aligns with the intended deployment environment. Compare performance metrics against alternative dual-port SRAM families for optimal cost-performance balance.

Part Context

This part belongs to the Renesas 71421 series of high-speed dual-port SRAMs. These devices are engineered for applications requiring fast, non-blocking data exchange between two masters. The series typically offers various speed grades and packaging options to accommodate different system constraints and form factors.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference parts. Ensure any substitute maintains identical pinout, voltage levels, and access times. Verify functional equivalence for dual-port operations before implementation.
