7005L35PFG

Overview

The Renesas Electronics Corporation 7005L35PFG 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 parallel interface access with a maximum access time of 35 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It supports surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible inputs and outputs allowing direct interfacing with standard digital logic systems.

Applications

• Stand-alone 64K-bit dual-port RAM modules
• Master/Slave dual-port configurations for 16-bit or wider word systems
• High-speed data buffering in embedded processing applications

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas documentation to confirm package type and lead finish. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 64-TQFP form factor.

Selection Notes

Select this component when true dual-port functionality is required for concurrent data access. Compare access times against system clock requirements to ensure the 35 ns speed meets timing constraints. Evaluate power consumption profiles if battery backup or low-power modes are critical for the application design.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs. The series offers various access speeds and packaging options to suit different performance and physical integration needs. It is designed for applications requiring high-speed data sharing between two independent processors or controllers.

Replacement Considerations

Official upgrade alternatives include the 7005L15PFG. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same package and thermal requirements.
