7005L12J8

Overview

The Renesas Electronics Corporation 7005L12J8 is an asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kbit, organized as 8k words by 8 bits. The component features a maximum access time of 12 ns and operates within a supply voltage range of 4.5 V to 5.5 V. Maximum power consumption is specified at 210 mA. The device supports parallel interface communication and functions within an operating temperature range of 0°C to +70°C. It is housed in a surface-mount PLCC-68 package.

Feature Summary

• Supports simultaneous independent read and write operations from two separate ports
• Provides high-speed asynchronous data transfer with 12 ns access time
• Compatible with standard 5V logic families for system integration

Applications

• High-performance digital signal processing systems requiring concurrent data access
• Network equipment buffer memory for packet switching applications
• Industrial control systems needing reliable volatile data storage

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Cross-reference datasheet specifications against current design requirements to ensure compatibility with existing 5V logic interfaces and timing constraints.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. The 12 ns speed grade offers a balance between performance and power consumption compared to faster variants. Ensure the design accommodates the PLCC-68 footprint and thermal characteristics associated with the 210 mA maximum current draw during active operation.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs, originally developed under IDT branding. The series is characterized by its ability to support complex multiprocessing architectures where multiple processors require immediate access to shared memory resources without bus contention.

Replacement Considerations

Public confirmed substitute part numbers include IDT7005L12J8.
