Memory IC Overview

The Renesas Electronics Corporation 7140SA100J is an asynchronous dual-port static random access memory (SRAM) device. It provides a storage capacity of 8 kbit, organized as 1K x 8 bits. The component features a parallel interface with a maximum access time of 100 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum supply current of 110 mA. The device is housed in a PLCC-52 package and supports surface mount installation. It is designed for commercial temperature operation between 0°C and +70°C.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations from two separate ports.

Memory IC Applications

High-speed data buffering in communication systems
Cache memory implementation in embedded processors
Real-time data logging applications

Memory IC Procurement Notes

Verify the specific suffix J indicates the PLCC-52 package variant when sourcing replacements. Confirm RoHS compliance status as older manufacturing runs may differ. Check for moisture sensitivity level requirements during handling. Ensure the supplier provides valid traceability documentation for legacy components. Validate pin compatibility if substituting into existing PCB layouts.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. The 100 ns speed suits moderate-frequency asynchronous interfaces. Verify that the PLCC-52 footprint matches the target design constraints. Consider the commercial temperature range suitability for the operating environment. Evaluate power consumption against system thermal limits given the 110 mA maximum current draw.
