IDT71V424L12PH8

Memory IC Overview

The IDT71V424L12PH8 is a 4Mb (512K x 8) asynchronous static random-access memory manufactured by Renesas Electronics Corporation. It operates on a single 3V to 3.6V supply and features a parallel interface with a maximum access time of 12ns. The component is housed in a 44-pin TSOP II package, measuring 0.400 inches wide, and supports surface-mount installation. Designed for commercial applications, it functions within a temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Asynchronous SRAM architecture requiring no clocks or refresh cycles
• Single 3.3V power supply operation
• LVTTTL-compatible inputs and outputs
• JEDEC center power and ground pinout

Memory IC Applications

• General-purpose data storage
• Buffering applications
• Cache memory systems

Memory IC Procurement Notes

Verify the exact suffix against official documentation, as variations exist between PHG8 and PH8 designations. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check current lifecycle status, as this part may be obsolete or subject to last-time-buy restrictions. Ensure compatibility with existing board layouts regarding the 44-TSOP II footprint.

Memory IC Selection Notes

Select this component when a 4Mb capacity with 12ns speed is required in a compact TSOP II form factor. Compare against the 71V424L10YGI for faster 10ns performance needs or the 71V424L12YG for SOJ packaging options. Consider the center power/ground pinout for noise reduction benefits in sensitive designs.

Memory IC Part Context

This device belongs to the 71V424 family of high-speed CMOS static RAMs. The family utilizes advanced low-power CMOS technology to deliver fast access times while maintaining low power consumption through chip deselect modes. The specific L12 designation indicates the 12ns speed grade within this product line.

Memory IC Replacement Considerations

Official substitutes include the 71V424S10YG and 71V424S15YG from Renesas Electronics Corporation.
