7006S12JI

Overview

The Renesas Electronics Corporation 7006S12JI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits, organized as 16K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 12 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation providing flexible timing control for data read and write cycles
• Parallel interface supporting standard digital logic levels for direct system integration

Applications

• Industrial control systems requiring high-speed data buffering
• Telecommunications equipment utilizing fast memory access
• Embedded systems needing independent port data handling

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 68-PLCC footprint specifications before assembly.

Selection Notes

Select this component when dual-port functionality is required for concurrent data processing tasks. Ensure the design accommodates the 68-PLCC package dimensions and thermal characteristics. Verify that the 4.5V to 5.5V operating voltage aligns with the target system power rails and that the 12ns access speed meets the application's timing constraints.

Part Context

This part belongs to the 7006 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and packaging options to suit different performance and form-factor requirements. The 7006S12JI specifically targets applications demanding reliable, high-speed memory buffering with independent port access capabilities.

Replacement Considerations

Check for official substitute part numbers provided by Renesas Electronics. Evaluate pin compatibility and electrical specifications if considering alternative vendors. Ensure any replacement maintains the dual-port architecture and PLCC package format to fit existing board layouts.
