71V424S15PH

Overview

The IDT 71V424S15PH is a standard asynchronous SRAM with a memory density of 4 megabits, organized as 512K words by 8 bits. It features a maximum access time of 15 nanoseconds and operates on a single 3-volt to 3.6-volt power supply. The device utilizes CMOS technology and is housed in a 32-pin Thin Shrink Small Outline Package (TSOP II).

Feature Summary

• Asynchronous parallel interface for direct system connection.
• Single low-voltage power supply operation.
• High-speed data access capabilities.

Applications

• General-purpose volatile memory storage.
• Buffering applications in digital systems.
• Cache memory implementations.

Procurement Notes

Verify the specific suffix 'PH' against official Renesas or IDT documentation to confirm package dimensions and pinout compatibility. Ensure RoHS compliance status matches project requirements, as manufacturing sources may vary. Confirm end-of-life status through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a 512K x 8 organization is required with 15ns speed limits. Verify that the 3.3V logic level aligns with the target system voltage. Consider the TSOP II footprint constraints during PCB layout design to ensure proper thermal and mechanical fit.

Part Context

This part belongs to the IDT 71V424 family of high-speed static random-access memories. The series typically includes variants with different access speeds and packaging options, such as SOJ or PLCC, allowing designers to choose based on performance and board space requirements within the same functional architecture.

Replacement Considerations

Check for equivalents like the IDT71V424L12YG or IDT71V424S10YG. Verify if the manufacturer has issued a product change notice affecting pinouts or electrical characteristics before substituting.
