7142LA55P

Overview

The Renesas Electronics Corporation 7142LA55P is a high-speed, 16K-bit (2K x 8) Dual-Port Static Random Access Memory (SRAM). It utilizes asynchronous dual-port technology with a parallel memory interface. The device features a 55 ns access time and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 48-pin Plastic Dual In-line Package (PDIP) designed for through-hole mounting. The component supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two processors
• Asynchronous operation with parallel interface for flexible system integration
• High-speed data transfer capabilities suitable for real-time processing applications

Applications

• Master-slave dual-port RAM configurations
• Real-time data buffering between independent processors
• High-speed cache memory systems

Procurement Notes

Verify the specific suffix requirements against official datasheets, as package and speed variants exist within the family. Confirm RoHS compliance status, as older revisions may not meet current environmental standards. Check for obsolescence notices or production change notifications before finalizing procurement plans.

Selection Notes

Select this component when a dedicated slave dual-port SRAM is required to pair with a master counterpart like the 7132 series. Ensure the design accommodates the 48-DIP footprint and through-hole assembly constraints. Verify that the 55 ns speed meets the system timing requirements.

Part Context

This part belongs to the 7142SA/LA series of high-speed dual-port SRAMs. It is specifically designed to function as a slave device in conjunction with 7132 series master dual-port RAMs, facilitating efficient data sharing between two independent bus masters without arbitration logic.
