71V416S12PHG

Overview

The Renesas Electronics 71V416S12PHG is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM). It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The device features a 12 ns access time and supports parallel interface communication. It is housed in a 44-pin Thin Small Outline Package (TSOP II) designed for surface-mount technology. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clock signals or periodic refresh cycles for data retention.
• 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 coupling.

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Industrial control system data storage

Procurement Notes

Verify the specific suffix PHG against official datasheets to confirm the TSOP-44 package and commercial/industrial temperature ratings. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into manufacturing processes.

Selection Notes

Select this component when a 256K x 16 organization is required with 12 ns speed performance. Ensure the design accommodates the 3.3V supply constraint and utilizes the center-ground pinout layout for optimal PCB routing.

Part Context

This part belongs to the 71V416 series of CMOS SRAMs, which provides non-volatile-like ease of use without the complexity of flash programming. The series offers various speed grades and package options to support diverse embedded memory needs.

Replacement Considerations

Check for IDT71V416S12PHG as a potential equivalent from Integrated Device Technology, noting that cross-manufacturer substitution requires verification of pin compatibility and electrical specifications.
