71V424L15PHG

Overview

The IDT71V424L15PHG is a 4-megabit asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and is organized as 512K words by 8 bits. The device operates within a supply voltage range of 3 volts to 3.6 volts and provides an access time of 15 nanoseconds. It is housed in a 44-pin Thin Shrink Small Outline Package (TSOP II) with a width of 0.400 inches (10.16 mm). The component supports surface mount installation and functions across a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous parallel SRAM architecture for high-speed data storage
• Compact 44-pin TSOP II surface-mount package design
• Standard 3.3-volt CMOS operation compatible with low-power systems

Applications

• Embedded memory systems requiring fast random access
• Industrial control units operating within standard temperature ranges
• Consumer electronics utilizing 3.3-volt logic interfaces

Procurement Notes

Verify the specific suffix PHG to confirm the 44-TSOP II package type, as other suffixes indicate different form factors like SOJ. Confirm RoHS compliance status, as manufacturing changes may affect regulatory adherence. Check for End-of-Life notices or Product Change Notifications regarding assembly site transfers or label modifications before finalizing procurement plans.

Selection Notes

Select this part when a 512K x 8 organization is required with 15-nanosecond performance. Ensure the application environment stays within the 0°C to 70°C commercial temperature limit. Verify that the system board layout accommodates the 44-lead TSOP II footprint and that the power supply strictly maintains the 3V to 3.6V operating window.

Part Context

This component belongs to the IDT 71V424 family of asynchronous SRAMs. The 'L' designation typically indicates the 15-nanosecond speed grade, while 'PHG' specifies the lead-free 44-TSOP II packaging variant. This series is designed for general-purpose memory applications where moderate density and fast access times are necessary.

Replacement Considerations

Officially recommended substitutes include the 71V424L10PHGI and 71V424L10PHG. These alternatives offer faster 10-nanosecond access times while maintaining the same 44-TSOP II package and electrical specifications.
