71V30L25TF8

Overview

The Renesas Electronics Corporation 71V30L25TF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features an 8 kbit storage capacity organized as 1K x 8 bits. The component supports parallel interface communication with a maximum access time of 25 ns. It operates on a single 3.3V power supply, with a voltage range from 3.0V to 3.6V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology. It functions within a commercial temperature range of 0°C to +70°C and includes automatic power-down capabilities controlled by chip enable signals.

Feature Summary

• True dual-ported architecture allowing simultaneous independent access to the same memory location from two separate ports.
• On-chip port arbitration logic manages data conflicts during concurrent read/write operations.
• Interrupt flags facilitate direct communication between the two ports without external microprocessor intervention.
• Battery backup operation capability ensures data retention down to 2V.

Applications

• High-speed data buffering in telecommunications equipment
• Real-time processing systems requiring low-latency memory access
• Industrial control systems needing reliable dual-port data exchange
• Network routers and switches for packet buffering

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as variations such as TFG8 or TFGI8 indicate specific packaging or temperature grades. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordered part matches the required industrial or commercial temperature rating. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit components.

Selection Notes

Select this component when simultaneous bidirectional data access is required without bus contention. The 25 ns access speed suits applications demanding rapid data throughput. Consider the 64-pin TQFP package constraints for PCB layout. Evaluate the need for interrupt-based port communication versus software polling. Verify that the 3.3V operating voltage aligns with the system's power domain.

Part Context

The 71V30L25TF8 belongs to the Renesas 71V30 series of dual-port SRAMs. This series is designed for applications requiring high-speed, independent access to shared memory resources. The L variant typically denotes 3.3V operation with battery backup support. The series offers various access times and temperature ranges to fit different performance and environmental requirements.

Replacement Considerations

Direct substitutes include other variants within the 71V30 series, such as those with different access times or temperature ratings. Verify pin compatibility and electrical specifications before substitution. Consult the official replacement guide for end-of-life notifications.
