71V416L10PHG

Overview

The IDT71V416L10PHG is a 4 Mbit asynchronous static random-access memory (SRAM) organized as 256K x 16 bits. Manufactured by Renesas Electronics, this component utilizes CMOS technology and operates on a single 3.3V supply voltage ranging from 3.0V to 3.6V. It features a parallel interface with a maximum access time of 10 ns. The device is housed in a 44-pin TSOP II surface-mount package. It supports LVTTL-compatible bidirectional inputs and outputs and requires no clock or refresh cycles for operation.

Feature Summary

• Fully static asynchronous circuitry eliminates the need for external clocks or periodic refresh operations.
• Bidirectional data inputs and outputs are compatible with LVTTL logic levels.
• Operates reliably from a single 3.3V power supply within specified voltage limits.

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor-based designs
• Data storage in industrial control applications

Procurement Notes

Verify the manufacturer designation, as Renesas Electronics is the current producer of this part number. Confirm the specific suffix 'PHG' corresponds to the 44-TSOP II package and commercial temperature range. Check for moisture sensitivity level requirements during handling. Ensure compatibility with LVTTL logic levels in the target system design before procurement.

Selection Notes

Select this component when a 256K x 16 bit organization is required for asynchronous SRAM applications. The 10 ns access speed suits high-performance buffering needs. Consider the 44-pin TSOP II package for surface-mount assembly constraints. Verify that the 3.3V operating voltage aligns with the system's power distribution network and that LVTTL input/output compatibility meets interface requirements.

Part Context

This part belongs to the 71V416L series of 4 Mbit SRAMs. It shares architectural similarities with other variants in the family, differing primarily in access speed and temperature rating suffixes. The 'L' typically denotes low-power characteristics, while '10' indicates the 10 ns speed grade. It is a legacy product originally from IDT, now managed under Renesas Electronics.

Replacement Considerations

Direct substitutes include IDT71V416L10PHGI for extended industrial temperature ranges. Other speed grades like 71V416L12PHG may serve as alternatives if slower speeds are acceptable. Verify pinout and electrical specifications match exactly before substitution.
