71V30L25TFG8

Overview

The 71V30L25TFG8 is a high-speed, 1K x 8 dual-port static RAM manufactured by Renesas Electronics. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The device features asynchronous parallel access from either port with a maximum access time of 25ns. It utilizes a 64-pin TQFP surface-mount package and supports commercial operating temperatures from 0°C to +70°C. The component includes automatic power-down capabilities for low standby power consumption.

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 efficient port-to-port communication
• Fully asynchronous operation allows flexible read and write cycles without clock synchronization requirements
• Battery backup capability ensures data retention down to 2V during primary power loss

Applications

• Stand-alone 8-bit dual-port SRAM implementations in embedded systems
• High-performance processor secondary cache applications requiring fast data buffering
• Industrial control systems utilizing asynchronous communication protocols
• Network equipment requiring reliable data storage with independent port access

Procurement Notes

Verify the specific suffix '8' indicates reel packaging rather than tray configuration when sourcing. Confirm RoHS compliance status as it may vary by production batch or region. Ensure the selected variant matches the required temperature grade and package type for your design constraints. Cross-reference manufacturer part numbers to avoid confusion with legacy IDT branding.

Selection Notes

Select this component when true dual-port functionality is required for concurrent data access. The 25ns access speed suits moderate-frequency asynchronous interfaces. Verify that the 64-pin TQFP footprint fits the PCB layout constraints. Consider the 3.3V supply requirement against system voltage rails. Evaluate if the commercial temperature range meets environmental specifications.

Part Context

This part belongs to the 71V30 series of dual-port SRAMs, which offers various access speeds and temperature grades. The 'L' designation typically indicates lower power characteristics compared to standard variants. The series provides flexibility for designs needing independent port control and shared memory resources without complex arbitration logic.

Replacement Considerations

Direct substitutes include the 71V30L25TFGI8 for industrial temperature ranges. The 71V30L35TFG8 offers slower 35ns access times but maintains similar electrical characteristics. Verify pin compatibility and functional equivalence before substitution.
