70V05S55J

Memory IC Overview

The Renesas 70V05S55J is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a total storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. It features a parallel interface and supports independent read/write operations at both ports simultaneously. The access time is specified at 55 nanoseconds. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two separate ports without bus contention.
• Enables flexible system architectures by functioning as a standalone memory or in master/slave configurations.
• Utilizes asynchronous logic to simplify interface timing requirements in complex digital systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential writes

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as variations exist between J and J8 packaging types. Confirm that the required operating temperature range aligns with the commercial grade specifications. Ensure compatibility with existing 3.3V logic levels before integration into the design.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Compare performance metrics against single-port alternatives if cost reduction is prioritized over throughput. Verify that the PLCC footprint matches the target printed circuit board layout constraints.

Memory IC Part Context

This part belongs to the 70V05 series of dual-port SRAMs from Renesas Electronics. The series includes variants with different access speeds and voltage tolerances. The 70V05S55J specifically targets applications needing moderate speed and standard 3.3V operation within a compact leadless package format.

Memory IC Replacement Considerations

IDT70V05S55J is a confirmed equivalent part number from the same manufacturer lineage. Verify pinout compatibility and electrical parameters before substitution.
