7006S12JI8

Overview

The Renesas Electronics Corporation 7006S12JI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 16k x 8 words. The device features a parallel interface with a maximum access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PLCC package measuring 24.21x24.21 mm.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation for flexible system integration without clock synchronization
• Parallel data interface supporting standard logic levels

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor designs
• Data storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure packaging specifications match assembly line capabilities. Validate lead times and obsolescence notices before finalizing purchase orders.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. The 12 ns access speed suits high-performance asynchronous applications. Consider the 68-PLCC package dimensions for PCB layout compatibility. Evaluate power consumption against system thermal limits given the 5.5 V maximum supply voltage specification.

Part Context

This part belongs to the Renesas 7006S series of dual-port SRAMs. It shares architectural similarities with other variants like the 7006S15J8 and 7006S20J, differing primarily in access speed and package type. The series is designed for applications requiring fast, independent port access without complex arbitration logic.

Replacement Considerations

The IDT7006S12JI8 is a confirmed equivalent part number from Integrated Device Technology, now part of Renesas. Verify pinout compatibility and electrical parameters before substitution. Other series members may require interface adjustments.
