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.
Feature Summary
- Dual-port architecture enabling independent simultaneous read/write operations from two separate ports.
Applications
- High-speed data buffering in communication systems
- Cache memory implementation in embedded processors
- Real-time data logging applications
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.
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.
Part Context
This part belongs to the IDT/Renesas 7140SA/LA series of CMOS dual-port SRAMs. These devices are widely used in industrial and commercial electronics requiring reliable non-volatile-like temporary storage without complex control logic. The series offers various speed grades and package options to fit diverse board space and performance needs.
