70V05L55J8

Memory IC Overview

The Renesas 70V05L55J8 is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 64 kilobits, organized as 8K words by 8 bits. It features an asynchronous parallel interface and supports independent read/write operations on both ports simultaneously. The device operates within a supply voltage range of 3.0 V to 3.6 V and provides a maximum access time of 55 ns. It is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount technology.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct processors or systems
• Asynchronous parallel interface supporting standard logic-level control signals
• Single 3.3 V power supply operation compatible with standard digital logic families

Memory IC Applications

• High-speed data buffering between asynchronous system components
• FIFO buffer implementations in communication interfaces
• Cache memory applications in embedded processing systems

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental directives. Validate pin compatibility and electrical specifications against target design constraints before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Ensure the design accommodates the 68-PLCC package dimensions and soldering profile. Verify that the 55 ns access speed meets system timing requirements compared to faster alternatives.

Memory IC Part Context

This component belongs to the 70V05L series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and packaging options to suit different performance and form-factor requirements in industrial and commercial electronic designs.

Memory IC Replacement Considerations

Check for direct cross-references such as IDT70V05L55J8. Evaluate alternative packages like TQFP if PLCC availability is limited. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
