71V424S10PHGI8

Overview

The 71V424S10PHGI8 is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It operates within a supply voltage range of 3 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-pin 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

• Provides high-speed asynchronous data access with a 10 ns maximum latency for efficient system integration.
• Supports wide 16-bit data organization to reduce pin count requirements compared to narrower interfaces.
• Operates on a standard 3.3 V CMOS power supply for compatibility with common logic families.

Applications

• High-performance embedded systems requiring fast local data storage
• Industrial control units operating in extended temperature environments
• Telecommunications equipment needing reliable volatile memory buffering

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for valid date codes and ensure proper handling procedures are followed during soldering to prevent damage to the package.

Selection Notes

Select this part when a 256K x 16 configuration is required with 10 ns speed. Ensure the design accommodates the 44-TSOP II footprint. Consider thermal management for operation near the upper temperature limit. Verify that the 3.3 V logic levels match the system bus requirements.

Part Context

This component belongs to the 71V424 series of asynchronous SRAMs. It shares architectural similarities with other variants like the 71V424L10YGI but differs in package type and data width. The series is designed for applications demanding low-power consumption and high-density memory solutions in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT71V424S10PHGI8. Verify pinout compatibility and electrical specifications before substitution.
