7005L20J8

Overview

The Renesas Electronics Corporation 7005L20J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The component features independent read/write ports for simultaneous access to the same memory location without conflict. It operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. The maximum access time is specified at 20 nanoseconds. The device is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Feature Summary

• True dual-ported architecture enabling simultaneous independent reads and writes from either port.

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave configurations for 16-bit or wider data bus expansion

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm the exact package variant and environmental compliance status. Confirm current production status as components in this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the 68-PLCC form factor during procurement planning.

Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two processors or controllers. The 20ns speed class suits applications needing moderate latency. Verify that the system design supports the 68-pin PLCC footprint and that the operating temperature range aligns with the commercial grade specifications provided in the datasheet.

Part Context

This part belongs to the 7005 family of dual-port SRAMs manufactured by Renesas Electronics. The family offers various speed grades and packaging options to support different system timing and physical layout requirements. The 7005 series is designed for applications requiring high-speed data sharing between multiple masters.

Replacement Considerations

Consult official substitution guides for equivalent parts within the 7005 series or compatible dual-port SRAM families. Verify pinout compatibility and electrical parameter alignment before replacing the component.
