71V30L35TFI

Memory IC Overview

The 71V30L35TFI is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 8 kbit organized as 1K x 8 bits with a maximum access time of 35 ns. The device operates on a single 3.3 V power supply within a voltage range of 3.0 V to 3.6 V and supports parallel interface communication. It is housed in a 64-pin TQFP package designed for surface-mount technology applications.

Memory IC Feature Summary

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

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Real-time signal processing systems requiring low-latency memory access
• Industrial equipment control units needing reliable dual-port data exchange
• Communication network interfaces managing concurrent data streams

Memory IC Procurement Notes

Verify the specific suffix designation carefully, as the 'I' grade indicates industrial temperature range specifications distinct from commercial variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level handling protocols are strictly followed during assembly to prevent package damage. Cross-reference pinout configurations with the latest datasheet revision to guarantee compatibility with existing circuit designs.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration hardware. The 35 ns speed suits moderate-frequency asynchronous interfaces where deterministic latency is critical. Consider the 64-pin TQFP footprint for board space constraints compared to larger packages. Evaluate power consumption requirements against the automatic power-down capabilities for battery-operated or energy-efficient designs.

Memory IC Part Context

This part belongs to the 71V30 series of high-speed dual-port SRAMs. It shares architectural similarities with other members like the 71V30L25 and 71V30S55, differing primarily in access speed and temperature grading. The series is designed for standalone 8-bit dual-port memory applications in embedded systems.

Memory IC Replacement Considerations

The IDT71V30L35TFGI8 is listed as a direct replacement alternative. Verify pin compatibility and electrical specifications before substitution. Note that suffix variations may indicate differences in packaging format or environmental ratings.
