71V416S12PHG8

Overview

The Renesas Electronics Corporation 71V416S12PHG8 is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM). It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. The device features a parallel interface and offers a maximum access time of 12 ns. It is housed in a 44-pin Thin Shrink Small Outline Package (TSOP-44) designed for surface-mount technology. The component supports an industrial operating temperature range from 0°C to +70°C.

Feature Summary

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

Applications

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• Temporary storage in telecommunications equipment

Procurement Notes

Verify the exact suffix against official Renesas documentation, as package variations exist within the family. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the specific revision matches design specifications. Cross-reference part numbers with legacy IDT equivalents if applicable. Validate lead-free status for environmental compliance.

Selection Notes

Select this component when a 3.3 V asynchronous SRAM with 12 ns speed is required. The TSOP-44 package suits space-constrained surface-mount designs. Consider the center power/ground pinout for improved performance. Verify that the 0°C to +70°C temperature range meets operational needs. Compare against faster or slower variants in the 71V416 series based on timing constraints.

Part Context

This part belongs to the 71V416 series of 4 Mbit CMOS SRAMs manufactured by Renesas Electronics. The series includes various speed grades and package options. The 'S' designation typically indicates a specific speed grade within the product line. These devices are widely used in industrial and commercial applications requiring reliable volatile memory storage.

Replacement Considerations

IDT71V416S12PHG8 is a confirmed equivalent part number for this component. Other speed grades such as 71V416S10 or 71V416S15 may serve as functional substitutes if timing requirements allow. Package compatibility must be verified when considering alternatives.
