71V416VL15PHG

Overview

The IDT71V416VL15PHG is a 4 Mbit (256K x 16) high-speed Static RAM fabricated using CMOS technology. It operates from a single 3.3V power supply and features an access time of 15 ns. The device utilizes a fully static asynchronous circuit design, eliminating the need for clocks or refresh cycles. It includes bidirectional data inputs and outputs that are TTL-compatible. The component is housed in a 44-pin Plastic SOJ package with JEDEC center power and ground pinout configuration.

Feature Summary

• Supports high-speed memory operations through advanced CMOS fabrication techniques
• Utilizes fully static asynchronous architecture requiring no external clock signals
• Features bidirectional I/O pins directly compatible with TTL logic levels

Applications

• High-speed data buffering in computer systems
• Cache memory applications in embedded controllers
• General-purpose volatile storage in industrial equipment

Procurement Notes

Verify the specific suffix 'VL' against official manufacturer documentation to confirm voltage range and temperature grade specifications. Ensure the package type matches the required 44-pin Plastic SOJ form factor. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Cross-reference the part number with current Renesas Electronics catalogs due to corporate acquisitions affecting product line availability.

Selection Notes

Select this component when a 256K x 16 organization is required for synchronous-like performance without clock overhead. The 15 ns access time suits moderate-speed digital logic interfaces. Verify that the system design accommodates the 3.3V supply requirement and that the 44-pin SOJ footprint aligns with the PCB layout constraints. Consider power consumption characteristics during active and deselected states.

Part Context

This part belongs to the IDT 71V416 family of 4 Mbit SRAMs. The family offers various speed grades and package options, including TSOP and SOJ configurations. The manufacturer, originally Integrated Device Technology, continues these products under Renesas Electronics following industry consolidation. These devices serve as standard parallel interface memory solutions for legacy and specialized hardware designs.

Replacement Considerations

Consult official datasheets for equivalent parts such as the IDT71V416S15Y or IDT71V416L15PHGI. Verify pin compatibility and electrical parameters before substitution. Note that package variations within the same speed grade may require physical adapter considerations.
