7142LA25JI

Overview

The Renesas Electronics Corporation 7142LA25JI is a high-speed 16Kbit (2K x 8) Dual-Port Static Random Access Memory (SRAM). It operates on a single 5.0V supply with a voltage range of 4.5V to 5.5V and features a 25ns access time. The device utilizes an asynchronous parallel interface and is housed in a 52-pin PLCC package. Designed for use as a 'SLAVE' dual-port RAM, it supports independent read/write operations by two masters.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two masters
• Asynchronous operation with fast 25ns access time
• Single 5.0V power supply compatibility

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current standards. Validate package integrity upon receipt. Check datasheet revisions for any pinout or electrical specification changes before integration into new designs.

Selection Notes

Select this component when dual-port functionality is required for master-slave configurations. Ensure system timing aligns with the 25ns access speed. Verify that the 52-PLCC package fits the PCB layout constraints. Consider the 5.0V logic level compatibility with existing circuitry.

Part Context

Part of the 7142 series designed specifically for dual-port SRAM applications. Intended to operate alongside 7132 series 'MASTER' dual-port RAMs. Provides non-volatile-like performance with volatile memory characteristics. Manufactured by Renesas Electronics Corporation.

Replacement Considerations

Check for direct substitutes within the 7142 series such as different access speeds. Verify pin-to-pin compatibility with alternative dual-port SRAMs from other manufacturers if sourcing new components.
