7005L55J

Overview

The Renesas Electronics Corporation 7005L55J 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 connectivity with a specified access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 68-pin Plastic Leadless Chip Carrier package measuring 24.21mm by 24.21mm. The component is rated for an ambient operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations from two separate ports.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications requiring concurrent port access

Procurement Notes

Verify the specific manufacturer source and document authenticity before procurement. Confirm that the component meets all required environmental and electrical specifications for the intended application. Ensure compatibility with existing system interfaces and power supplies. Check for any discontinuation notices or lifecycle status updates from the manufacturer.

Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing concurrent data access. Consider the 68-PLCC package constraints and the 55ns speed performance relative to system timing requirements. Evaluate the commercial temperature range suitability against the operational environment conditions.

Part Context

This part belongs to the 7005L series of dual-port SRAMs manufactured by Renesas Electronics. The series typically offers various speed grades and packaging options to accommodate different design needs. The 7005L55J specifically targets applications requiring moderate speed performance in a compact surface-mount form factor.

Replacement Considerations

Cross-reference with other 64Kb dual-port SRAMs offering similar 55ns access times and 68-PLCC packages. Verify pinout compatibility and electrical characteristics before substitution.
