71V424S12PHG8

Overview

The 71V424S12PHG8 is a 4 Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3.3 V supply voltage within the range of 3 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 44-pin Thin Small Outline Package (TSOP II). It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation without requiring external clocks or refresh cycles
• JEDEC center power and ground pinout configuration for noise reduction
• LVTTL-compatible bidirectional inputs and outputs
• Single 3.3 V supply voltage operation

Applications

• High-speed data buffering in embedded systems
• Cache memory applications in microcontroller-based designs
• Industrial control system data storage
• Telecommunications equipment signal processing

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures. Check for manufacturer recommended replacements if new production is required. Ensure compliance with RoHS3 specifications for environmental standards.

Selection Notes

Select this component for applications requiring fast asynchronous access times with low power consumption. Consider the 44-pin TSOP II package constraints for PCB layout. Evaluate thermal performance within the specified industrial temperature range. Compare against newer generation SRAMs for size and speed optimization.

Part Context

This part belongs to the 71V424 family of 4 Mbit SRAMs. It shares architectural similarities with other variants like the 71V424S12YGI but differs in package type and temperature rating. The PHG suffix indicates a specific lead-free, green compound package suitable for surface mount technology applications.

Replacement Considerations

The 71V424S12PHGI is listed as a manufacturer recommended replacement. Verify pin compatibility and electrical specifications before substitution. Other family members may require adapter solutions or design modifications.
