71V30L35TFGI

Overview

The 71V30L35TFGI is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 8 kilobits organized as 1K x 8 bits. The device supports a supply voltage range of 3.0 V to 3.6 V and offers a maximum access time of 35 nanoseconds. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 10 mm x 10 mm footprint. The component operates within an industrial temperature range of -40 °C to +85 °C and complies with RoHS3 standards.

Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from both ports.
• On-chip port arbitration logic facilitates interrupt flags for direct communication between the two ports.
• Fully asynchronous operation allows flexible read and write cycles controlled independently by each port's chip enable signals.
• Automatic power-down feature reduces standby current when chip enables are deactivated.

Applications

• High-speed data buffering in telecommunications equipment requiring low-latency parallel interfaces.
• Industrial control systems needing reliable memory for real-time processing under varying thermal conditions.
• Embedded applications utilizing battery backup for data retention during primary power loss.

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required packaging and environmental standards. Confirm that the selected variant matches the necessary operating temperature range and voltage specifications for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring independent dual-port access without external arbitration hardware. Ensure the system design accommodates the 64-pin TQFP package dimensions and pitch constraints. Verify that the 3.3 V supply rail stability meets the specified tolerance requirements for consistent asynchronous performance across the full industrial temperature spectrum.

Part Context

This part belongs to the 71V30 series of high-speed dual-port SRAMs, designed for standalone 8-bit memory applications. The series provides flexibility through various access times and packaging options, catering to diverse embedded memory needs in consumer, industrial, and communications sectors while maintaining TTL-compatible logic levels.

Replacement Considerations

Direct substitutes include the 71V30L35TFGI8, which shares identical electrical characteristics but utilizes tape-and-reel packaging instead of trays. Other variants within the 71V30 family may offer different access speeds or temperature grades but require verification of pinout and functional compatibility.
