71V30S25TF8

Memory IC Overview

The 71V30S25TF8 is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 8 kilobits organized as 1K x 8 bits. The device supports parallel interface access with a maximum access time of 25 nanoseconds. It operates on a single 3.3V power supply, compatible with TTL logic levels. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) designed for surface-mount technology applications.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from both ports.
• On-chip port arbitration logic facilitates efficient management of concurrent read and write operations.
• Integrated interrupt flags support direct communication and status signaling between the two ports.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'TF8' against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as older variants may differ. Check current product lifecycle status, as this part number may be obsolete or subject to last-time buy restrictions. Ensure voltage requirements match the target system design.

Memory IC Selection Notes

Select this component when true dual-port functionality is required for simultaneous access without external arbitration. Compare access times against system clock speeds to ensure timing compatibility. Evaluate pin count and package dimensions against available PCB real estate. Consider alternative members of the 71V30 family if different speed grades or temperature ranges are needed.

Memory IC Part Context

This component belongs to the 71V30 series of high-speed dual-port SRAMs. The series offers various speed grades and packaging options to suit different performance and form-factor requirements. It is designed for applications needing independent access from two masters, distinguishing it from standard single-port SRAMs.

Memory IC Replacement Considerations

Consult official substitution guides for verified equivalents within the 71V30 series. Verify pinout compatibility before replacing with other packages like PLCC. Cross-reference speed grades and operating temperatures to ensure functional parity.
