71V424L10PHG

Overview

The Renesas Electronics Corporation 71V424L10PHG is a static random access memory (SRAM) device with a storage capacity of 4 Mbit, organized as 512K x 8. It operates asynchronously with a parallel interface and supports a supply voltage range from 3 V to 3.6 V. The component features a maximum access time of 10 ns and a maximum power supply current of 165 mA. Designed for surface mount installation, it is housed in a TSOP-44 package. The device functions within an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Asynchronous operation with parallel data interface
• CMOS technology for low power consumption
• Industrial temperature range support

Applications

• Data buffering in embedded systems
• Cache memory for microcontrollers

Procurement Notes

Verify the specific suffix PHG against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check for product discontinuance notifications or lifecycle changes prior to procurement. Ensure compatibility with existing board designs regarding pinout and voltage levels.

Selection Notes

Select this component when a 512K x 8 asynchronous SRAM is required for industrial environments. Consider the 10 ns access speed and TSOP-44 form factor for space-constrained applications. Evaluate power requirements against the specified 165 mA maximum current. Compare against other members of the 71V424L series for alternative speeds or packages.

Part Context

This part belongs to the Renesas 71V424L series of asynchronous SRAMs. It shares architectural similarities with other variants in the family, differing primarily in access speed, package style, and operating temperature range. The series provides non-volatile-like performance with volatile memory characteristics.

Replacement Considerations
