7007L12JI

Overview

The Renesas Electronics Corporation 7007L12JI is a dual-port static random-access memory (SRAM) IC with a storage capacity of 256 Kbit, organized as 32K x 8. It features an asynchronous parallel interface and a maximum access time of 12 ns. The device 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 24.21 x 24.21 mm.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation for flexible timing integration without clock synchronization requirements
• High-speed data transfer capability with 12 ns access time for rapid memory retrieval

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• FIFO buffer applications in telecommunications equipment

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may differ. Validate package integrity upon receipt, ensuring the 68-PLCC leads are undamaged. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement orders.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 12 ns speed suits applications needing faster access than standard SRAMs. Ensure the design accommodates the 68-PLCC footprint and 4.5V–5.5V power supply constraints. Consider thermal management for SMD installations in enclosed environments.

Part Context

This part belongs to the Renesas 7007L series of dual-port SRAMs, offering varying access speeds such as 15 ns and 20 ns variants. It serves as a high-performance memory solution for industrial and commercial applications requiring reliable, fast, and independent port access for complex data management tasks.

Replacement Considerations

Compatible substitutes include IDT7007L12JI and other 7007L series parts with matching 12 ns access times and 68-PLCC packaging. Verify electrical parameters and pin compatibility before substitution.
