71V424L10PHGI8

Overview

The 71V424L10PHGI8 is a 4 Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 44-TSOP II package with a width of 10.16 mm. It supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation with fast 10 ns access time for high-speed data retrieval
• Single power supply operation compatible with standard 3.3 V logic systems
• Industrial-grade reliability with extended operating temperature range
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• High-performance embedded storage in industrial control systems
• Data buffering in telecommunications equipment
• Cache memory in consumer electronics requiring fast access
• Automotive infotainment and instrument cluster applications

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during assembly.

Selection Notes

Select this part when a 512K x 8 organization is required with 10 ns speed performance. Consider the 44-TSOP II package dimensions for PCB layout compatibility. Evaluate power consumption requirements against the specified maximum current limits. Compare alternative speeds if system timing allows for slower access times to potentially reduce cost.

Part Context

This component belongs to the 71V424L series of asynchronous SRAMs, designed for general-purpose memory applications. It represents a legacy product line from Renesas, formerly IDT, offering reliable static memory solutions. The series provides various speed grades and package options to suit different design constraints while maintaining consistent electrical characteristics across the family.

Replacement Considerations

Direct substitutes include 71V424L10PHG and 71V424L10PHGI. Verify pinout compatibility and electrical specifications before substitution. Alternative packages such as SOJ may require mechanical adaptation.
