7006S17PFI

Overview

The Renesas Electronics Corporation 7006S17PFI is a high-speed Dual-Port Static RAM (SRAM) with a storage capacity of 128Kbit, organized as 16K x 8. It features parallel interface access and write cycle times of 17 ns. The device operates on a supply voltage range of 4.5V to 5.5V and supports an extended industrial operating temperature range from -40°C to +85°C. It is housed in a 64-TQFP package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• High-speed asynchronous operation with 17 ns access time
• Extended industrial temperature rating for reliable performance in harsh environments

Applications

• Real-time data buffering between independent processing systems
• High-speed cache memory in embedded control applications
• Data logging and transfer interfaces in industrial automation equipment

Procurement Notes

Verify the specific suffix 'I' confirms the -40°C to +85°C industrial temperature range, as standard variants may differ. Confirm RoHS compliance status, as older production runs may not meet current environmental directives. Check for obsolescence notices or end-of-life notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without external arbitration logic. Ensure the system design accommodates the 4.5V to 5.5V power supply requirements. Verify that the 64-TQFP package dimensions fit the available PCB real estate and thermal management constraints.

Part Context

This part belongs to the IDT7006 series of high-speed dual-port SRAMs. It serves as a standalone memory solution for applications requiring fast, independent read/write operations from two distinct ports. The series is designed to replace slower synchronous memories in latency-sensitive digital signal processing tasks.

Replacement Considerations

The 7006L15PFG is listed as an upgrade alternative. Note that the L-series variant typically offers a faster 15 ns access time but may have different temperature or packaging specifications. Verify pin compatibility and electrical characteristics before substitution.
