70V05S35J8

Memory IC Overview

The 70V05S35J8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features parallel interface access with a maximum access time of 35 nanoseconds and a write cycle time of 35 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts and supports surface-mount installation in a 68-lead Plastic Leadless Chip Carrier (PLCC) package. The component functions reliably across an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through separate ports for each side of the memory array.
• Utilizes asynchronous logic allowing flexible timing control without reliance on a global clock signal.
• Provides high-speed data transfer capabilities suitable for buffering and temporary data storage applications.

Memory IC Applications

• Data buffering between components operating at different clock speeds
• Temporary storage in telecommunications equipment interfaces
• Cache memory implementation in embedded processing systems

Memory IC Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements against project specifications as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 68-PLCC footprint. Review datasheet revisions for any updates regarding electrical characteristics or handling instructions before integration into final designs.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access from two independent masters. Ensure system power rails align with the specified 3V to 3.6V operating range. Consider the 35ns access speed relative to processor cycles. Evaluate the 68-PLCC package dimensions against available board space constraints. Verify that the asynchronous nature fits the target system's timing architecture without requiring complex synchronization logic.

Memory IC Part Context

This device belongs to the 70V05 series of dual-port SRAMs, designed for high-performance memory applications. The series typically offers various access speeds and organization options to suit different bandwidth requirements. As a legacy product from Renesas, it represents established technology for systems prioritizing reliability and proven performance over newer, faster alternatives.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-reference parts. Check for updated series members offering improved speed grades or enhanced environmental compliance. Verify pin compatibility if substituting with similar dual-port SRAMs from other manufacturers.
