7140LA25PFG8

Overview

The 7140LA25PFG8 is a CMOS dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features an 8K x 8 organization, providing a total storage capacity of 64 kbit. The device supports asynchronous parallel interface operation with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a surface-mount TQFP-64 package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate ports
• Asynchronous parallel interface for straightforward integration into digital systems
• CMOS technology ensuring low power consumption during operation

Applications

• Data buffering in high-speed communication interfaces
• Cache memory implementation in embedded processing systems
• Temporary data storage in industrial control applications

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm the TQFP-64 package and lead-free status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as regulatory status can vary by production batch. Ensure the ordering quantity aligns with factory packaging requirements specified in the product datasheet.

Selection Notes

Select this component when a 64 kbit dual-port SRAM with 25 ns access speed is required. It is suitable for designs needing independent read/write capabilities on separate ports. Verify that the system operates within the 4.5 V to 5.5 V voltage range and requires a 64-pin surface-mount package.

Part Context

This part belongs to the 7140LA series of dual-port SRAMs from Renesas Electronics. The series is characterized by CMOS technology and asynchronous operation. The 7140LA25 variant specifically denotes the 25 ns access time performance tier within this family.

Replacement Considerations

IDT7140LA25PFG8 is a confirmed substitute part number.
