7005S12J

Overview

The Renesas Electronics Corporation 7005S12J is a 64Kbit (8K x 8) dual-port static random-access memory (SRAM) IC. It features asynchronous parallel interface with a maximum access time of 12 ns. The device operates on a single 5V power supply, ranging from 4.5V to 5.5V. It is housed in a 68-pin PLCC package with dimensions of 24.21mm x 24.21mm. The component supports standard TTL logic levels and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation for flexible system integration without clock synchronization
• Integrated hardware support for bus arbitration via semaphore and interrupt signals

Applications

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

Procurement Notes

Verify the specific suffix J indicates the 68-PLCC package configuration. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check lead availability due to potential end-of-life status. Ensure voltage requirements match the 4.5V to 5.5V specification. Validate pinout compatibility with existing PCB layouts before ordering.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Choose based on the 12 ns speed grade for moderate performance needs. Consider the PLCC package for through-hole mounting requirements. Evaluate power consumption against system thermal constraints. Compare alternative speeds if higher throughput is necessary.
