71V30S25TFI

Overview

The Renesas Electronics Corporation 71V30S25TFI is an asynchronous dual-port static random-access memory (SRAM) with a density of 8 kilobits, organized as 1K x 8. It operates on a single 3.3V power supply and features a parallel interface with a maximum access time of 25 nanoseconds. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 10x10 mm footprint. It supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location by both ports
• On-chip port arbitration logic for managing concurrent read/write operations
• Interrupt flags facilitating direct communication between the two ports

Applications

• High-speed data buffering in telecommunications equipment
• Real-time signal processing systems requiring low-latency memory access
• Industrial control networks utilizing asynchronous parallel interfaces

Procurement Notes

Verify component status carefully as this specific part number may be obsolete or discontinued. Confirm availability through authorized distributors and check for valid RoHS compliance documentation. Ensure that any substitute components maintain identical pinout compatibility and electrical specifications to prevent integration issues.

Selection Notes

Select this component when true dual-port functionality is required for simultaneous data exchange without external arbitration. The 25ns access speed suits high-performance applications. Verify that the TQFP-64 package fits the board layout constraints and that the operating voltage aligns with the system's 3.3V logic levels.

Part Context

This device belongs to the 71V30 series of high-speed dual-port SRAMs. It shares architectural similarities with variants like the 71V30L25 and 71V30L35 but differs in specific packaging and commercial/industrial temperature ratings. The 'S' designation typically indicates standard commercial or specific industrial grade variations within the family.

Replacement Considerations

The 71V30L35TFGI is listed as a direct replacement option. Verify that the substitute matches the required access time and temperature range specifications for the target application.
