71V424L12PHG8

Overview

The 71V424L12PHG8 is a 4Mb (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3V to 3.6V power supply and features a parallel interface with a maximum access time of 12 ns. The device is housed in a 44-TSOP II surface-mount package, measuring 0.400 inches (10.16 mm) wide. It supports an operating temperature range of 0°C to 70°C (TA).

Feature Summary

• Asynchronous SRAM architecture requiring no clock or refresh cycles.
• Parallel data interface for standard system integration.
• Single 3.3V supply operation compatible with LVTTL logic levels.

Applications

• General-purpose volatile data storage in embedded systems.
• Cache memory buffers in industrial control units.
• Data buffering in telecommunications equipment.

Procurement Notes

Verify the specific suffix PHG8 against official Renesas documentation to confirm the exact package variant and RoHS compliance status. Confirm current production status as legacy components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component when a 512K x 8 organization is required with 12 ns speed performance. Ensure the design accommodates the 44-TSOP II footprint and operates within the specified 3V to 3.6V voltage range and commercial temperature limits.

Part Context

This part belongs to the 71V424 family of high-speed asynchronous SRAMs from Renesas. It shares architectural similarities with other variants in the series but is distinguished by its specific 12 ns access time and TSOP II packaging configuration.

Replacement Considerations

Publicly confirmed substitutes include 71V424L10PHG and 71V424L15PHG. Verify pin compatibility and timing specifications before substitution.
