7142SA25J8

Memory IC Overview

The Renesas Electronics Corporation 7142SA25J8 is a high-speed, 16Kb (2K x 8) dual-port static random-access memory (SRAM). It operates with a parallel interface and features an access time of 25 ns. The device supports a single power supply voltage ranging from 4.5V to 5.5V. It is housed in a 52-pin PLCC surface-mount package and is designed for industrial temperature applications.

Memory IC Feature Summary

True dual-ported memory cells allow simultaneous independent access to the same memory location by two separate ports without conflict.
Includes a BUSY input flag mechanism to manage data integrity during simultaneous access attempts on shared addresses.
Features an automatic power-down mode controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in embedded processing systems
Data storage in network switching hardware

Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. Sourcing should prioritize verified suppliers to ensure authenticity and proper handling of obsolete electronic components.

Memory IC Selection Notes

Select this part when a true dual-port SRAM solution is required for systems needing simultaneous read/write operations from two distinct masters. It serves as a slave device in conjunction with master dual-port RAMs to expand word width. Ensure the design accommodates the 52-PLCC package and 5V logic levels.

Memory IC Part Context

The 7142SA series belongs to Renesas' legacy portfolio of high-speed dual-port SRAMs. These devices are engineered to function as slave units alongside master dual-port memories, enabling full-speed, error-free operation in wider data bus configurations without requiring additional discrete logic gates for arbitration.
