7140SA25J8

Overview

The Renesas Electronics Corporation 7140SA25J8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time and write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm x 19.13mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• High-speed data buffering in industrial control systems.

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Ensure compliance with RoHS non-compliance status and MSL level 3 handling requirements during procurement and assembly processes.

Selection Notes

Select this part only if legacy 52-PLCC packaging and specific 25ns timing are required. Verify that the 4.5V to 5.5V supply range matches the system design. Consider the discontinued status when planning long-term production lifecycles.

Part Context

The 7140SA25J8 belongs to the IDT7140SA/LA family of high-performance dual-port SRAMs manufactured by Renesas Electronics. This series is designed for applications requiring fast, independent port access without clock synchronization.
