7005S20J

Overview

The Renesas Electronics Corporation 7005S20J is an asynchronous dual-port static random access memory (SRAM) device. It provides a storage capacity of 64 kbit, organized as 8k words by 8 bits. The component features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 290 mA. The device is designed for surface mount installation in a PLCC-68 package. It functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• Integrated control logic including busy flags and interrupt capabilities

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as standard versions may not meet current environmental directives. Validate package integrity upon receipt, as moisture sensitivity requires proper handling. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing design integration.

Selection Notes

Select this component when independent read/write ports are necessary for concurrent data processing. Ensure the 20 ns access time meets system timing constraints. Verify that the PLCC-68 footprint aligns with PCB layout specifications. Consider thermal management requirements given the maximum power consumption levels during active operation.

Part Context

This part belongs to the 7005 series of high-speed dual-port SRAMs originally developed by IDT and later acquired by Renesas. The series offers various speed grades and packaging options to suit different performance and form factor requirements in industrial and commercial electronics.
