71V30L35TFGI8

Overview

The Renesas Electronics Corporation 71V30L35TFGI8 is an asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 8Kb, organized as 1K x 8 bits. It operates on a single 3.3V ±0.3V power supply and features a parallel interface with a maximum access time of 35 ns. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 10x10 mm. It supports an industrial operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• True dual-ported memory 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 reads or writes to any memory location without clock synchronization.
• Automatic power-down feature controlled by chip enable signals reduces standby power consumption.

Applications

• High-speed data buffering in embedded systems requiring concurrent read/write operations
• Industrial equipment control interfaces needing reliable asynchronous memory access
• Battery-backed backup memory applications supporting low-voltage data retention

Procurement Notes

Verify the specific suffix 'I8' indicates tape-and-reel packaging rather than tray configuration when ordering. Confirm the RoHS3 compliance status matches current regulatory requirements for your region. Ensure the industrial temperature grade (-40°C to +85°C) aligns with your system's environmental specifications. Cross-reference the manufacturer part number with official Renesas documentation to avoid confusion with obsolete variants like the TFI8 series.

Selection Notes

Select this component when true dual-port functionality is required for simultaneous data exchange without external arbitration hardware. The 35 ns access speed suits moderate-to-high frequency asynchronous interfaces. Consider the 64-TQFP package constraints for PCB layout space. Verify that the 3.3V logic levels are compatible with the host microcontroller or processor I/O voltages.

Part Context

This device belongs to the 71V30 family of high-speed dual-port SRAMs. It serves as a successor or alternative to older IDT-branded versions, maintaining pin compatibility and functional equivalence within the 71V30 series. The 'L' designation typically denotes the 3.3V core voltage variant with battery backup capabilities.

Replacement Considerations

The 71V30L35TFI8 is listed as an obsolete direct substitute. Verify if the 'I' suffix implies different packaging or temperature grades compared to the active 'I8' version. No other cross-manufacturer equivalents are confirmed in the provided data.
