71V424L12PHGI8

Overview

The 71V424L12PHGI8 is a 4-Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates with a supply voltage range of 3.0 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 II (TSOP II) with a width of 10.16 mm. It supports surface-mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous parallel memory architecture for direct data access
• CMOS technology ensuring low power consumption during operation
• Single 3.3 V power supply compatibility for system integration

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing volatile memory buffers
• Consumer electronics utilizing standard SRAM interfaces

Procurement Notes

Verify the exact suffix PHGI8 against official Renesas documentation to confirm package type, lead-free status, and humidity sensitivity level. Ensure the component meets RoHS3 compliance requirements for your specific manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts, as this series has undergone production transfers.

Selection Notes

Select this component when a 512K x 8 organization is required with 12 ns speed performance. It is suitable for designs constrained by the 44-TSOP II footprint. Consider alternative speeds or densities if higher capacity or faster access times are needed. Verify that the operating temperature range aligns with the final application environment.

Part Context

This part belongs to the 71V424 family of high-speed asynchronous SRAMs from Renesas. The family includes variants with different access speeds and packaging options. The 71V424 series is widely used in legacy and current embedded applications where simple parallel SRAM interfaces are preferred over complex serial memories.

Replacement Considerations

Check for pin-compatible alternatives within the same 71V424 series. Verify if slower speed grades can function as drop-in replacements. Confirm that any substitute maintains the 44-TSOP II package and 3.3 V operating voltage.
