7142SA25J

Overview

The Renesas Electronics Corporation 7142SA25J is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Applications

• High-speed data buffering in communication equipment.

Procurement Notes

Verify component authenticity through authorized channels due to potential availability issues. Confirm RoHS compliance status, as the specific part may not meet current environmental directives. Check for moisture sensitivity handling requirements during storage and assembly processes. Ensure compatibility with existing system voltage levels before integration.

Selection Notes

Select this component when independent dual-port memory access is required for high-speed applications. Verify that the 52-PLCC package fits the target PCB layout constraints. Ensure the operating temperature range meets the specific environmental conditions of the intended deployment scenario.

Part Context

This component belongs to the Renesas 7142SA series of dual-port SRAMs. These devices are designed for applications requiring fast, independent read/write operations from two distinct ports.
