71V424L15Y

Overview

The IDT71V424L15Y is a high-speed asynchronous static random-access memory (SRAM) IC with a total storage capacity of 4 megabits. The memory array is organized as 512K words by 8 bits. It features a parallel interface and supports an access time of 15 nanoseconds. The device operates within a supply voltage range of 3 volts to 3.6 volts. It is housed in a 36-lead small outline J-leaded package (SOJ) designed for surface-mount installation.

Feature Summary

• High-speed asynchronous operation with 15 ns access time
• Parallel data interface for direct system connection
• Single 3V to 3.6V power supply requirement

Applications

• Embedded systems requiring fast local data storage
• Industrial control equipment memory buffers
• Telecommunications signal processing units

Procurement Notes

Verify the specific suffix against official Renesas or IDT documentation, as variants such as YI may indicate different temperature ranges or packaging. Confirm RoHS compliance status, as some listings indicate non-compliance. Check for obsolescence notices, as this component family has been subject to product change notifications and discontinuation updates. Ensure the 36-SOJ package availability matches current manufacturing capabilities.

Selection Notes

Select this component when a 4Mb parallel SRAM with 15 ns speed is required in a 36-lead SOJ package. Compare against other 71V424 series variants if different temperature grades or pinouts are needed. Verify that the 3V to 3.6V operating voltage aligns with the target system's power rails. Consider lead times and end-of-life status due to the component's age and manufacturer transitions.

Part Context

This part belongs to the IDT 71V424 series of high-speed static RAMs. Integrated Device Technology was acquired by Renesas Electronics Corporation. The series typically includes various speed grades and package options. The 71V424L15Y specifically denotes the 15 nanosecond access time variant in the standard SOJ form factor.

Replacement Considerations

Check for direct substitutes within the IDT/Renesas 71V424 family with compatible pinouts. Verify electrical compatibility for any cross-manufacturer replacements. Note that newer generations may use different packages like TSOP or BGA.
