71V416S15PHG

Overview

The 71V416S15PHG is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) manufactured by IDT, now part of Renesas Electronics. It operates on a single 3.3V supply with a voltage range of 3.0V to 3.6V. The device features a parallel interface and offers a maximum access time of 15 ns. It is housed in a 44-pin Thin Shrink Small Outline Package (TSOP II), designated as PHG44. The component supports surface-mount installation and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Fully static asynchronous operation requiring no clock signals or periodic refresh cycles
• LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
• Center power and ground pinout configuration to optimize signal integrity

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor architectures
• FIFO buffer applications in communication interfaces

Procurement Notes

Verify the current manufacturing status, as this component may be subject to discontinuation notices. Confirm that the specific suffix 'PHG' corresponds to the TSOP-44 package variant required for your design. Ensure compatibility with RoHS3 standards if environmental compliance is mandatory for the target market.

Selection Notes

Select this component when a 4 Mbit capacity with 16-bit width is required at a 15 ns speed grade. The TSOP-44 package is suitable for space-constrained surface-mount designs. Consider the center power/ground pinout for improved performance compared to edge-powered alternatives in high-frequency applications.

Part Context

This part belongs to the 71V416 family of 3.3V CMOS SRAMs. It shares architectural similarities with variants like the 71V416S12 and 71V416L series, differing primarily in access speed and package type. The product line represents standard asynchronous memory solutions from Integrated Device Technology before its acquisition by Renesas.

Replacement Considerations

The 71V416S15PHGI8 is a manufacturer-recommended alternative offering identical electrical specifications but packaged in a reel format instead of tape and reel.
