71V30S25TF

Memory IC Overview

The Renesas Electronics Corporation 71V30S25TF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features an 8 kbit storage density organized as 1K x 8 bits with parallel interface access. The component operates on a single 3.3V power supply and supports simultaneous independent reads or writes from two separate ports. Key electrical parameters include a maximum access time of 25 ns, a minimum operating voltage of 3 V, and a maximum operating voltage of 3.6 V. The device is housed in a 64-pin TQFP package suitable for surface mount technology.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location from both ports without conflict.
• On-chip port arbitration logic manages bus contention automatically during simultaneous access scenarios.
• Integrated interrupt flags facilitate direct communication and status signaling between the two independent ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency dual-port interaction.
• Real-time signal processing systems utilizing independent processor access to shared memory buffers.
• Industrial control networks employing asynchronous communication protocols between multiple microcontrollers.

Memory IC Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required packaging and temperature grades. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference part numbers with manufacturer obsolescence notices to avoid sourcing discontinued variants. Ensure procurement channels provide authentic components with traceable documentation.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration hardware. Compare access times and power consumption metrics against alternative dual-port SRAMs for optimal system performance. Evaluate package dimensions and pin configurations to match existing printed circuit board layouts. Consider industrial temperature range options if operation exceeds standard commercial limits.

Memory IC Part Context

This component belongs to the 71V30 series of dual-port SRAMs manufactured by Renesas Electronics. The series provides scalable memory solutions for applications demanding high-speed, non-blocking data exchange. Variants within the family differ primarily in access speed, temperature rating, and packaging style while maintaining consistent functional architecture.

Memory IC Replacement Considerations

Direct substitutes may include other 71V30 series variants with matching pinouts and electrical characteristics. Verify that replacement parts maintain identical dual-port functionality and interrupt flag capabilities. Check for any changes in package dimensions or thermal requirements when transitioning between different speed grades or temperature ranges.
