71V416S15PHGI

Overview

The Renesas Electronics 71V416S15PHGI is a static random access memory device organized as 256K x 16, providing a total storage capacity of 4 Mbit. It operates with an asynchronous parallel interface and features a maximum access time of 15 ns. The component supports a supply voltage range from 3 V to 3.6 V, with a maximum power consumption of 170 mA. Designed for surface mount applications, it is housed in a TSOP-44 package. The device functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes fully static asynchronous circuitry that requires no clock signals or periodic refresh cycles for operation.
• Features LVTTL-compatible bidirectional inputs and outputs for direct interfacing with standard logic families.
• Operates from a single 3.3V CMOS supply, simplifying power distribution requirements in embedded systems.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network infrastructure hardware

Procurement Notes

Verify the specific suffix PHGI against official datasheets to confirm pinout compatibility and lead-free status. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly. Check for recent product change notifications regarding manufacturing site transfers or material updates. Ensure the source document explicitly lists this part number as active or available.

Selection Notes

Select this component when a 256K x 16 organization is required with 15 ns access speed. It is suitable for designs needing LVTTL compatibility and single-supply operation. Compare against the 71V416L series if lower power consumption is critical, noting potential differences in operating voltage ranges. Verify package availability in TSOP-44 format.

Part Context

This part belongs to the Renesas 71V416S/L family of high-speed SRAMs. The 'S' designation typically indicates a specific performance grade or feature set within the broader 71V416 portfolio. It shares architectural similarities with other members like the 71V416L15PHGI but may differ in electrical characteristics such as current consumption or voltage tolerance.

Replacement Considerations

The IDT71V416S15PHG is listed as a manufacturer-recommended alternative. Verify pin-to-pin compatibility and electrical specifications before substitution. Other variants in the 71V416S series may offer different access times or packaging options.
