71V124SA15PHG8

Overview

The 71V124SA15PHG8 is a 1-Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates on a single 3.0V to 3.6V power supply and features a 15 ns access time. The device utilizes a parallel interface and is housed in a 32-TSOP II surface-mount package. It supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Asynchronous operation without clock or refresh requirements
• JEDEC center power and ground pinout for noise reduction
• LVTTL-compatible bidirectional I/O lines

Applications

• General-purpose data storage in embedded systems
• Cache memory for microcontrollers
• Buffer memory in industrial control units

Procurement Notes

Verify the specific suffix PHG8 against official Renesas documentation to confirm the 32-TSOP II package and extended temperature range. Confirm RoHS compliance status as indicated in current datasheets. Check for obsolescence notices, as this component family may have discontinued variants.

Selection Notes

Select this part when a 1-Mbit capacity with 15 ns speed is required in a compact TSOP II form factor. Ensure the system design accommodates the 3.3V logic levels and the specific pinout configuration. Verify that the thermal environment stays within the specified -40°C to +85°C operational limits.

Part Context

This component belongs to the 71V124 series of high-speed CMOS SRAMs. The series is characterized by low power consumption and compatibility with standard logic families. The SA variant typically denotes specific speed grades and package options within the broader product line.
