71V30VL90TF

Memory IC Overview

The Renesas Electronics Corporation 71V30VL90TF is a high-speed, 8-kbit dual-port static random-access memory (SRAM) organized as 1K x 8 bits. It operates on a single 3.3V power supply with a specified access time of 90 nanoseconds. The device features true dual-ported memory cells allowing simultaneous independent access to the same memory location from two separate ports. It includes on-chip port arbitration logic and interrupt flags for efficient port-to-port communication. The component supports battery backup operation with data retention down to 2V and utilizes a 64-pin STQFP package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read/write access to identical memory locations via separate control and I/O pins.
• Integrated on-chip port arbitration logic and interrupt flags designed to facilitate direct communication between the two ports.
• Supports battery backup functionality ensuring data retention at voltages as low as 2V for critical information preservation.

Memory IC Applications

• High-speed data buffering in industrial automation systems requiring concurrent data handling
• Real-time signal processing applications needing immediate dual-port memory access
• Communication interface circuits utilizing port-to-port interrupt signaling for synchronization

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the specific suffix matches the required package type and temperature grade. Check for RoHS compliance status and moisture sensitivity level requirements relevant to your assembly process. Ensure the part number corresponds exactly to the 90ns speed variant and 3.3V operation specifications.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration hardware. Consider the 90ns access speed relative to system clock requirements. Evaluate the need for battery backup capabilities if non-volatile storage is necessary during power transitions. Compare package dimensions against available PCB space constraints.

Memory IC Part Context

This component belongs to the 71V30 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to suit different performance and form factor requirements. It is designed for standalone use as an 8-bit dual-port memory solution in complex electronic systems.

Memory IC Replacement Considerations

Direct substitutes within the 71V30 series include variants with different access times such as 71V30L25 or 71V30L35, provided the speed difference meets system timing requirements. Verify pin compatibility and electrical characteristics before substitution.
