7005L35JI

Overview

The Renesas Electronics Corporation 7005L35JI is a high-speed 64K-bit (8K x 8) dual-port static random-access memory. It features asynchronous parallel operation with a maximum access time of 35 ns. The device operates on a single 5V power supply within a range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. It is housed in a 68-pin PLCC package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads of the same memory location from both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage concurrent access.
• Automatic power-down feature controlled by chip enable signals to achieve low standby power consumption.
• TTL-compatible inputs and outputs allowing direct interface with standard digital logic systems.

Applications

• Stand-alone 64K-bit dual-port RAM configurations
• Master/Slave dual-port RAM combinations for 16-bit or wider data bus systems
• Industrial control systems requiring reliable data buffering

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches the required package and temperature grade.

Selection Notes

Select this part when simultaneous independent access to shared memory is required without external arbitration logic. Consider the 68-pin PLCC package for surface-mount assembly needs. Verify that the 35 ns speed meets system timing constraints. Ensure the industrial temperature range aligns with the operational environment.

Part Context

The 7005 series represents a family of high-speed dual-port SRAMs designed for applications requiring concurrent data access. The 7005L35 variant specifically offers 35 ns access times. This component serves as a bridge between different processing domains, facilitating efficient data exchange in complex embedded architectures.
