7005L55J8

Overview

The Renesas Electronics Corporation 7005L55J8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features parallel interface access with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 68-lead Plastic Leadless Chip Carrier package measuring 24.21mm by 24.21mm. The component functions reliably across an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read and write operations on two separate ports for high-throughput data handling
• Utilizes asynchronous logic architecture requiring no external clock signal for operation
• Provides non-volatile data retention during power loss events typical of SRAM technology

Applications

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

Procurement Notes

Verify the specific suffix J8 against official manufacturer documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as historical records indicate potential non-compliance for this series. Validate that the component meets current environmental regulations for your target market before integration into final assemblies.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Ensure the system design accommodates the 55-nanosecond access latency. Verify that the 68-pin PLCC footprint aligns with the printed circuit board layout constraints and thermal management requirements.

Part Context

This part belongs to the Renesas 7005L series of dual-port SRAM devices. The series offers various speed grades and packaging options to suit different performance and form-factor requirements. The 7005L55J8 specifically targets applications needing moderate speed with a standard leadless chip carrier package.

Replacement Considerations

Consult official substitution guides for compatible parts such as the IDT7005L55J8. Verify pin compatibility and electrical specifications before replacing existing inventory.
