7005S35J8

Overview

The Renesas Electronics Corporation 7005S35J8 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 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Feature Summary

• Supports simultaneous independent reads and writes from two distinct ports without bus contention
• Includes on-chip hardware logic for semaphore signaling and port arbitration between masters and slaves
• Provides automatic low-power standby mode controlled by chip enable inputs
• Offers TTL-compatible I/O levels for direct interfacing with standard digital logic

Applications

• Stand-alone dual-port memory modules in embedded systems
• Master-slave configurations for expanding data bus widths in 16-bit or larger architectures
• High-speed buffering applications requiring concurrent data access
• Industrial control systems utilizing asynchronous communication protocols

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm the exact package variant and tape-and-reel specifications. Confirm RoHS compliance status as legacy components may vary. Check for End-of-Life notices or discontinuance announcements prior to procurement planning. Ensure compatibility with existing PCB footprints for the 68-PLCC form factor.

Selection Notes

Select this component when a system requires true dual-port capability for concurrent data handling without external arbitration logic. The 35ns speed grade suits moderate-frequency asynchronous interfaces. Consider the 68-PLCC package constraints for surface-mount assembly processes. Evaluate power consumption requirements against the specified operating current limits.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs, which are designed for flexible memory expansion and high-performance data buffering. The series supports various access speeds and packaging options to accommodate different system timing and physical layout requirements.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers.
