71V424S15PHGI

Overview

The IDT71V424S15PHGI is a 4Mbit (512K x 8) asynchronous static random-access memory manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 3.6V and features a parallel interface with a maximum access time of 15ns. The device is housed in a 44-lead Thin Small Outline Package (TSOP II) designed for surface-mount installation. It supports an industrial operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Asynchronous parallel SRAM architecture providing independent read and write operations without clock synchronization.
• Industrial-grade thermal stability supporting reliable operation across extended temperature ranges.
• CMOS technology ensuring low power consumption during active and standby modes.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control units

Procurement Notes

Verify the specific suffix 'PHGI' against official Renesas documentation to confirm package type, lead finish, and environmental compliance status. Confirm current availability as this component series may be subject to discontinuation notices or production line transfers. Ensure compatibility with existing board layouts regarding the 44-TSOP II footprint and pin configuration before procurement.

Selection Notes

Select this component when a 4Mbit capacity with 8-bit word width is required for asynchronous applications. The 15ns speed grade suits systems needing moderate access latency. Verify that the 44-TSOP II package dimensions fit the target PCB space and that the 3V to 3.6V supply voltage aligns with the system's power rails.

Part Context

This part belongs to the IDT 71V424 family of high-performance asynchronous SRAMs. The 'S' designation typically indicates a specific speed bin or package variant within the broader product line. These devices are engineered for general-purpose memory applications requiring fast, non-volatile-free data retention and simple interface protocols.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Potential replacements include other members of the 71V424 family with compatible pinouts and electrical characteristics, such as variants with different access times or package styles, provided they meet the system's timing and physical constraints.
