71V124SA15PHGI

Memory IC Overview

The Renesas Electronics Corporation 71V124SA15PHGI is a static random-access memory (SRAM) integrated circuit organized as 128K x 8 bits, providing a total storage capacity of 1 Mbit. It operates with an asynchronous parallel interface and features a maximum access time of 15 ns. The device is designed for a single 3.3 V power supply, functioning within a voltage range of 3 V to 3.6 V. It utilizes a 32-pin TSOP II surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Asynchronous operation without the need for external clocks or refresh cycles
• JEDEC center power and ground pinout configuration to reduce noise generation
• LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing

Memory IC Applications

• Embedded systems requiring fast local data buffering
• Industrial equipment control units
• Consumer electronics with high-speed memory requirements

Memory IC Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for product change notifications regarding packaging or material updates. Ensure proper ESD handling procedures are followed during storage and installation to maintain device integrity.

Memory IC Selection Notes

Select this component when a 1 Mbit non-volatile buffer is required in a compact TSOP II footprint. The 15 ns access speed suits applications needing moderate performance. Verify that the system design accommodates the 3.3 V logic levels and the specified industrial temperature range constraints.

Memory IC Part Context

This part belongs to the 71V124SA series of 3.3V CMOS SRAMs. It shares architectural similarities with other members like the 71V124SA12PHG but offers a slower 15 ns access time compared to faster variants. The series is characterized by low power consumption and compatibility with standard LVTTL logic families.

Memory IC Replacement Considerations

The IDT71V124SA15PHGI is a documented alias for this component. Other potential substitutes include parts from the same family with compatible pinouts and electrical specifications, subject to availability.
