71V30L25TF

Overview

The Renesas Electronics Corporation 71V30L25TF is a high-speed, 8-kbit (1K x 8) dual-port static random-access memory (SRAM). It operates asynchronously with a maximum access time of 25 nanoseconds. The device supports a single 3.3V power supply within a voltage range of 3.0V to 3.6V. It features true dual-ported memory cells allowing simultaneous independent access from two ports. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) and is designed for commercial temperature ranges.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read/write operations from separate ports
• On-chip port arbitration logic manages access conflicts between the two ports
• Interrupt flags facilitate direct communication and status signaling between ports
• Automatic power-down mode reduces standby current when chip enable signals are inactive

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring independent host and peripheral access
• Real-time signal processing buffers in industrial control systems

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required packaging and environmental specifications. Confirm that the 64-pin TQFP package dimensions align with the target PCB footprint. Check for RoHS compliance status relevant to the manufacturing date code. Ensure the selected variant meets the intended operating temperature range requirements for the final assembly environment.

Selection Notes

Select this component when independent concurrent access to shared memory is required without external arbitration circuitry. The 25ns access speed suits moderate-to-high frequency asynchronous interfaces. Consider the 64-pin TQFP package constraints for board space. Evaluate power consumption profiles if battery backup or low-power standby modes are critical design parameters.

Part Context

This part belongs to the 71V30 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and temperature grades. The 71V30L25TF specifically denotes the 25ns speed grade in the commercial temperature range. It serves as a standalone memory solution for applications needing parallel interface simplicity and dual-port functionality.

Replacement Considerations

Direct substitutes include other variants within the 71V30 family such as the 71V30L25TFG or 71V30L35TFGI, provided pinouts and electrical characteristics match. Verify package compatibility and temperature ratings before substitution.
