7005L12J

Overview

The Renesas Electronics Corporation 7005L12J is a static random-access memory (SRAM) device organized as 8K x 8 bits, providing a total storage capacity of 64 Kbit. It operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. The component features an asynchronous parallel interface with a maximum access time of 12 ns. Designed for surface-mount applications, it is housed in a 68-pin PLCC package. The device supports standard dual-port operations and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports independent simultaneous read/write operations at two separate ports
• Provides fast asynchronous data access via parallel interface
• Operates on a standard single 5V power supply

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Data storage in industrial control equipment

Procurement Notes

Verify the specific package variant and suffix codes against official Renesas documentation, as legacy part numbers may have multiple revisions. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited production runs. Ensure compliance with RoHS directives if required by your application specifications.

Selection Notes

Select this component when a small-capacity, high-speed dual-port SRAM is required for parallel data handling. The 12 ns access speed suits moderate-to-high frequency applications. Consider the 68-PLCC package constraints for PCB layout. Evaluate alternative parts from the same family if different access speeds or package types are needed for cost or space optimization.

Part Context

The 7005L series represents a family of dual-port SRAMs manufactured by Renesas Electronics. These devices are designed for applications requiring concurrent access from two independent masters. The 7005L12J specifically denotes the 12 ns speed grade within this architecture, offering a balance between performance and power consumption for general-purpose memory tasks.

Replacement Considerations

Check for direct substitutes such as the IDT7005L12J, which shares identical pinouts and functionality. Verify that any replacement maintains the 68-PLCC package and 12 ns access time requirements.
