7005S12JI8

Overview

The Renesas Electronics Corporation 7005S12JI8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 64 kbit, organized as 8k words by 8 bits. 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 read/write operations on separate ports
• Asynchronous operation without requiring a system clock signal for data transfer
• CMOS technology ensuring low power consumption during standby and active states

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast access

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 the specific package variant matches design specifications. Check for end-of-life notices or obsolescence warnings before finalizing purchase orders.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling between different system buses. The 12 ns access speed suits high-performance applications needing rapid data retrieval. Consider the 68-PLCC package dimensions for PCB layout compatibility. Evaluate power supply stability within the 4.5 V to 5.5 V range to ensure reliable operation under varying load conditions.
