7140LA25PFG

Overview

The Renesas Electronics Corporation 7140LA25PFG is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Pack (TQFP) package measuring 14x14 millimeters. The component functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports for high-throughput data handling.
• Utilizes CMOS technology to deliver low power consumption characteristics suitable for battery-operated systems.
• Features a parallel interface architecture designed for straightforward integration into digital logic circuits.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the exact suffix codes on the component marking against official datasheets to confirm pin compatibility and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for obsolescence notices or product change notifications from the manufacturer to ensure long-term availability and supply chain stability.

Selection Notes

Select this component when a system requires independent concurrent access to shared memory resources without external arbitration logic. Ensure the design accommodates the specific 64-TQFP footprint and thermal dissipation requirements. Validate that the operating voltage and speed parameters align with the target application's timing constraints and power budget.

Part Context

This part belongs to the IDT 7140SA/LA series of dual-port SRAMs manufactured by Renesas Electronics. The series is characterized by its ability to facilitate efficient data transfer between different clock domains or processors. It serves as a critical interconnect component in complex electronic architectures requiring reliable, high-speed temporary data storage.

Replacement Considerations

Consult official manufacturer documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout, voltage ratings, and access times to guarantee functional compatibility without redesigning the host circuit board.
