71V30S35TFI

Overview

The Renesas Electronics Corporation 71V30S35TFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It features an 8Kb storage capacity organized as 1K words by 8 bits. The device operates with a single 3.3V power supply and supports parallel interface connections. It provides independent read/write access to any memory location from either port without conflict. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 10x10mm footprint. It is designed for commercial temperature ranges and includes automatic power-down capabilities to minimize standby current consumption.

Feature Summary

• True dual-ported architecture allowing simultaneous independent access to the same memory location from both ports
• On-chip arbitration logic manages conflicts between simultaneous accesses from Port A and Port B
• Fully asynchronous operation enables flexible timing control for both read and write cycles
• Automatic power-down feature reduces standby power consumption when chip enable signals are inactive

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring fast write speeds
• Network switch buffer memory
• Industrial control system temporary storage

Procurement Notes

Verify the specific suffix 'S' indicates commercial temperature range specifications compared to industrial variants. Confirm package type matches design requirements. Check RoHS compliance status for current production versions. Ensure voltage levels align with system 3.3V standards. Validate lead-free status if required by assembly processes.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external multiplexing. Consider the 35ns access time for moderate speed applications. Evaluate power consumption needs against the automatic power-down feature. Compare pin compatibility with existing PCB layouts using the 64-TQFP package. Assess thermal performance within the specified operating temperature range.

Part Context

The 71V30 series represents Renesas' high-performance dual-port SRAM family. These devices bridge the gap between standard single-port SRAMs and complex FIFOs. They offer true dual-ported functionality with integrated arbitration. The series supports various access times and temperature grades. This specific model targets cost-sensitive commercial applications requiring reliable dual-port memory.

Replacement Considerations

Direct replacements include other 71V30 series variants with different access times or temperature ratings. Verify pin-to-pin compatibility before substitution. Check if updated suffixes indicate packaging or environmental changes. Ensure electrical parameters match original design constraints.
