71V416YL12PHG

Overview

The IDT71V416YL12PHG is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3.3 V supply with a voltage range of 3 V to 3.6 V. The device features a parallel interface and a maximum access time of 12 ns. It is housed in a 44-pin BSOJ package with a width of 0.400 inches (10.16 mm). The component supports surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation.
• Bidirectional inputs and outputs are LVTTL-compatible for direct logic interfacing.
• Center power and ground pinout design to optimize signal integrity and reduce noise.

Applications

• High-speed data buffering in telecommunications equipment.
• Cache memory implementation in embedded computing systems.
• Data storage in industrial control and automation hardware.

Procurement Notes

Verify the manufacturer designation, as this part number is associated with Renesas Electronics following corporate acquisitions. Confirm RoHS compliance status, as specific suffixes may indicate lead-free or non-compliant variants. Check for Product Change Notices regarding packaging or material updates. Ensure the 44-BSOJ package dimensions match the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a 256K x 16 organization is required for synchronous-like performance without clock dependencies. The 12 ns access speed suits moderate-to-high frequency applications. Consider the 44-BSOJ package constraints against available board space. Verify that the 3.3 V operating voltage aligns with the system's power distribution network and I/O logic levels.

Part Context

This device belongs to the 71V416 family of high-performance CMOS SRAMs. The family offers various access speeds and package options, including TSOP and SOJ configurations. The 'YL' suffix typically denotes a specific package variant within the series. These components are designed for applications demanding fast read/write cycles and low power consumption in portable and desktop environments.

Replacement Considerations

Compatible substitutes include the IDT71V416S12YGI8 and IDT71V416L12PHG. Verify pin compatibility and electrical specifications before substitution. Note that some variants may differ in moisture sensitivity levels or RoHS compliance status.
