7142SA55J

Memory IC Overview

The Renesas Electronics Corporation 7142SA55J is a static random-access memory integrated circuit featuring 16Kb of storage capacity organized as 2K by 8 bits. It utilizes an asynchronous dual-port architecture with parallel interface technology, allowing independent access to the same memory array from two separate ports. The device 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. It provides a maximum access time and write cycle time of 55 ns, functioning reliably across an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

Supports simultaneous independent read and write operations through dual-port architecture
Utilizes CMOS technology for high-speed asynchronous data transfer
Provides parallel interface connectivity for direct system integration

Memory IC Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in industrial control systems

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as the device does not meet current standards. Validate package integrity upon receipt. Check datasheet revisions for any parameter updates. Ensure compatibility with existing board designs before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Consider the 55 ns speed for moderate performance needs. Evaluate the 52-PLCC package for surface mount constraints. Verify voltage compatibility with 5V logic systems. Assess thermal management for the specified operating temperature range.

Memory IC Part Context

This part belongs to the 7142SA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7142SA55P but differs in packaging. The series is designed for applications requiring fast, independent port access without complex arbitration logic.
