71V30L25TFI

Overview

The 71V30L25TFI is a high-speed, 8Kbit (1K x 8) dual-port static random-access memory manufactured by Renesas Electronics. It operates on a single 3.3V power supply with a specified access time of 25 nanoseconds. The device features true dual-ported memory cells allowing simultaneous independent access to the same location from two ports. It supports fully asynchronous operation and includes on-chip port arbitration logic for interrupt flags. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) and is designed for industrial temperature ranges.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read/write access to shared memory locations
• On-chip port arbitration logic providing interrupt flags for efficient port-to-port communication
• Fully asynchronous operation from either port without requiring clock synchronization
• Automatic power-down feature controlled by chip enable signals for low standby power consumption

Applications

• High-speed data buffering in telecommunications equipment
• Real-time data logging systems requiring concurrent access
• Industrial control systems needing isolated dual-port memory interfaces
• Network switch buffer applications

Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm it denotes the Industrial temperature grade (-40°C to +85°C). Confirm package type is 64-TQFP. Check current product status as availability may vary. Ensure RoHS compliance matches project requirements. Validate pinout compatibility if replacing existing components.

Selection Notes

Select this component when simultaneous independent access to the same memory address is required. Choose based on the 25ns speed grade for high-performance needs. Verify voltage compatibility with the 3.3V system. Consider the TQFP package for surface-mount assembly. Evaluate power consumption requirements given the automatic power-down capabilities.

Part Context

This part belongs to the 71V30 family of dual-port SRAMs. It shares architectural similarities with other variants like the 71V30L25TFG and 71V30L35TFGI, differing primarily in speed grade and temperature range specifications. The family is designed for applications requiring non-blocking memory access between two independent masters.

Replacement Considerations

Check for direct substitutes such as IDT71V30L25TFI or equivalent parts from other manufacturers offering identical 1Kx8 dual-port SRAM specifications. Ensure replacement parts match the 25ns access time and 64-TQFP package dimensions.
