7140LA25J

Overview

The 7140LA25J is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-PLCC package measuring 19.13x19.13 mm. The component is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

Supports simultaneous independent read/write operations on two ports without bus contention
Utilizes high-speed CMOS technology for low power consumption and fast cycle times
Provides flexible configuration through dedicated chip select and output enable controls

Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in embedded processing systems
Data logging and temporary storage in industrial control units

Procurement Notes

Verify component authenticity due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity handling procedures during assembly. Validate pin compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave memory operations. Consider the 25ns access speed for applications demanding rapid data exchange between processors. Ensure the 52-PLCC package fits the available board space and manufacturing capabilities.

Part Context

This part belongs to the 7140SA/LA series of dual-port SRAMs. It is often paired with the 7130 series master dual-port RAM to form complete memory subsystems. The LA suffix typically denotes specific packaging or temperature grade variations within the broader product family.
