71V30L35TF

Overview

The Renesas Electronics Corporation 71V30L35TF 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 independent access from two separate ports with dedicated control, address, and I/O pins. It operates on a single 3.3V power supply and provides a maximum access time of 35 ns. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology applications.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location from both ports.
• On-chip port arbitration logic manages concurrent access requests without external intervention.
• Interrupt flags facilitate direct communication and status signaling between Port A and Port B.
• Automatic power-down mode controlled by chip enable inputs reduces standby power consumption.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging and temporary storage in industrial control units

Procurement Notes

Verify the specific suffix requirements against the official datasheet, as package and temperature variants exist within the 71V30 series. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the selected variant matches the required operating temperature range and pinout configuration for the target PCB design.

Selection Notes

Select this component when independent dual-port access is required for shared memory resources. The 35 ns speed grade suits moderate-to-high frequency asynchronous interfaces. Consider the 64-pin TQFP footprint constraints and 3.3V logic compatibility during system architecture definition. Evaluate interrupt flag usage for complex multi-master coordination scenarios.

Part Context

The 71V30 series represents Renesas' high-performance dual-port SRAM family designed for applications requiring simultaneous read/write operations from two distinct masters. This specific model utilizes advanced CMOS technology to deliver low power consumption alongside fast access times. The series is widely adopted in networking and industrial automation sectors where data integrity and concurrent access are critical.

Replacement Considerations

Direct substitutes include the IDT71V30L35TFGI8 and other variants within the 71V30L35 family. Verify pin compatibility and electrical specifications before substitution. Alternative packages such as STQFP may require mechanical redesign.
