71V424L15PHG

Overview

The IDT71V424L15PHG is a high-speed asynchronous static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology. It provides a total storage capacity of 4 megabits, organized as 512K words by 8 bits. The device features a parallel interface with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and is designed for surface-mount installation in a 32-pin Thin Small Outline Package (TSOP II).

Feature Summary

• Asynchronous parallel memory architecture providing fast data access.
• High-density 4-megabit storage capacity suitable for complex system buffering.
• Surface-mount package design optimized for automated PCB assembly.

Applications

• Data buffering in telecommunications equipment.
• Cache memory implementation in embedded computing systems.
• General-purpose volatile storage in industrial control units.

Procurement Notes

Verify the specific suffix 'PHG' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Confirm that the 15ns speed grade matches the target system timing requirements. Check current availability status as older SRAM components may be subject to discontinuation notices or limited production runs from Renesas Electronics.

Selection Notes

Select this component when a 4Mb density with 15ns latency is required in a compact 32-pin TSOP form factor. Ensure the host system supports 3.3V logic levels and asynchronous parallel interfaces. Consider thermal dissipation capabilities within the SMD package if operating near the upper temperature limits.

Part Context

This part belongs to the IDT 71V424 family of 4M-bit asynchronous SRAMs. Variants within this series typically differ by access speed grades, package types, and environmental compliance suffixes. The L15 designation indicates the specific 15-nanosecond performance tier within the product line.

Replacement Considerations

Consult official cross-reference lists for direct replacements such as the IDT71V424L15PFG or equivalent parts from Renesas. Verify electrical parameters and pin configurations before substitution.
