71V424L12PHGI

Overview

The Renesas Electronics Corporation 71V424L12PHGI is a static random-access memory (SRAM) integrated circuit with a total storage capacity of 4 megabits. The device utilizes an asynchronous parallel interface and features a memory organization of 512K words by 8 bits. It operates within a supply voltage range of 3 volts to 3.6 volts. The component supports surface-mount installation in a 44-pin Thin Shrink Small Outline Package (TSOP II). The specified access time for this model is 12 nanoseconds, and it is designed for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel memory interface for direct system integration
• Industrial-grade wide operating temperature range capability
• CMOS technology ensuring low power consumption during operation

Applications

• Embedded systems requiring non-volatile data retention during power cycles
• Industrial control units operating in extreme environmental conditions
