71V424L15PHGI

Overview

The 71V424L15PHGI is a 4-Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 15 ns and operates within a supply voltage range of 3.0 V to 3.6 V. The device is housed in a 44-pin Thin Shrink Small Outline Package (TSOP II) designed for surface-mount technology. 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 fast data access without external clock synchronization
• Industrial-grade thermal stability ensuring reliable operation across extended temperature ranges
• Surface-mount TSOP II packaging optimized for high-density printed circuit board layouts

Applications

• Embedded systems requiring non-volatile-like speed with volatile storage characteristics
• Industrial control units needing robust performance under varying environmental conditions
• Communication equipment buffer memory applications

Procurement Notes

Verify the component status as End-of-Life (EOL) through official Renesas channels before procurement planning. Confirm that the 44-TSOP II package dimensions match your existing footprint requirements. Ensure compliance with RoHS3 specifications if required by your manufacturing standards. Check for available manufacturer-recommended alternatives due to potential supply constraints associated with discontinued parts.

Selection Notes

Select this component when a 4-Mbit capacity with 15 ns access speed is required in a 44-pin surface-mount package. It is suitable for designs needing wide industrial temperature tolerance and standard 3.3V logic compatibility. Consider pin-compatible or functionally equivalent newer generations if long-term availability is a primary constraint for the product lifecycle.

Part Context

This part belongs to the Renesas 71V424 family of high-speed asynchronous SRAMs. The 'L' suffix typically denotes specific package or temperature variants within the series, while 'PHGI' indicates lead-free, halogen-free, and green material composition. It serves as a legacy solution for parallel memory interfaces in established industrial and commercial electronic designs.

Replacement Considerations

Consult Renesas documentation for officially recommended replacements such as the 71V424L10PHGI or other members of the 71V424 series. Verify electrical and mechanical compatibility before substitution.
