IDT71V416S20PHG8

Memory IC Overview

The IDT71V416S20PHG8 is a 4 Megabit (256K x 16-bit) high-speed CMOS Static RAM. It operates on a single 3.3V power supply and features LVTTL-compatible bidirectional data inputs and outputs. The device utilizes fully static asynchronous circuitry, eliminating the need for external clocks or refresh cycles. It includes dedicated upper and lower byte enable pins for selective data access.

Memory IC Feature Summary

• JEDEC center power and ground pinout configuration to reduce electrical noise
• Equal access and cycle times for consistent performance
• Single chip select and output enable pin architecture
• Bidirectional I/Os directly compatible with LVTTL logic levels

Memory IC Applications

• High-speed memory buffering in embedded systems
• Cache memory applications requiring fast random access
• Data storage in industrial control environments
• Telecommunications equipment signal processing

Memory IC Procurement Notes

Verify that the specific suffix 'HG8' corresponds to the standard TSOP Type II package as documented in official Renesas/IDT ordering guides. Confirm the component meets RoHS compliance standards required by your manufacturing facility. Ensure the commercial temperature range of 0°C to +70°C aligns with your system's operational environment before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4Mb capacity with a 16-bit word width is required. The synchronous interface is not applicable; this is an asynchronous SRAM. Consider the 44-pin TSOP Type II package for surface-mount assembly constraints. Verify that the 3.3V operating voltage matches the target system's power rails and that LVTTL compatibility satisfies the host controller's logic requirements.

Memory IC Part Context

This part belongs to the IDT71V416 family of 4-Megabit SRAMs manufactured by Integrated Device Technology, now part of Renesas Electronics. The family offers various speed grades and packages, including SOJ and BGA options. The 'S' designation indicates standard power consumption characteristics within this product line.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Substitutes must match the 256K x 16 organization, 3.3V supply, and 44-pin TSOP package. Verify timing parameters against the original design specifications.
