7006S17JI

Overview

The Renesas Electronics Corporation 7006S17JI is a high-speed, 128-kbit (16K x 8) dual-port static random-access memory. It features fully asynchronous parallel operation with a 17 ns access time and operates on a single 5V power supply ranging from 4.5 V to 5.5 V. The device supports simultaneous independent reads and writes from either port, utilizing true dual-ported memory cells. It includes on-chip hardware for semaphore signaling and interrupt flags, housed in a 68-pin PLCC package suitable for surface mount installation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read and write operations from both ports without conflict.
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate efficient port arbitration.
• Fully asynchronous interface allowing flexible timing control for both Port A and Port B connections.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider data bus expansion
• High-speed buffer applications requiring concurrent data access

Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm the exact package type and temperature grade, as suffixes define physical form factors. Confirm moisture sensitivity levels and lead-free status requirements prior to ordering. Ensure compatibility with existing PCB footprints for the 68-pin PLCC variant if applicable.

Selection Notes

Select this component when concurrent independent access to shared memory is required without external arbitration logic. The 17 ns speed suits moderate-to-high frequency asynchronous interfaces. Consider the 68-pin PLCC package constraints for board space and thermal management within the specified industrial temperature range.

Part Context

The 7006 series represents a family of high-speed dual-port SRAMs designed for complex system architectures. This specific model belongs to the S-series, typically denoting standard industrial specifications. It serves as a critical interconnect element in embedded systems needing reliable, low-latency data sharing between multiple processors or controllers.

Replacement Considerations

Cross-reference with IDT7006S17JI for pin-compatible alternatives from Integrated Device Technology. Verify electrical parameter equivalence, particularly access times and power consumption, before substituting.
