70V05L15J

Memory IC Overview

The Renesas Electronics Corporation 70V05L15J is an asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kbit, organized as 8K words by 8 bits. The component features a parallel interface with a maximum access time of 15 ns. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum power supply current of 185 mA. The device supports single data rate (SDR) operations and functions within an ambient temperature range of 0°C to +70°C. It is housed in a 68-pin PLCC surface-mount package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in communication systems.

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as variations exist within the product family. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Check for moisture sensitivity level requirements during handling. Ensure the selected package matches the target PCB footprint. Validate that the operating temperature range aligns with the final application environment.

Memory IC Selection Notes

Select this component when independent port access is required for concurrent data processing tasks. Consider the 15 ns access speed for timing-critical interfaces. Evaluate the 68-PLCC package constraints for board layout. Compare power consumption specifications against system thermal limits. Verify compatibility with the host system's voltage levels and signal integrity requirements.

Memory IC Part Context

This part belongs to the 70V05L series of dual-port SRAMs from Renesas Electronics. The series offers various access speeds and packaging options to suit different design needs. The 70V05L15J specifically targets applications requiring fast, non-blocking memory access between two distinct logic domains or processors.

Memory IC Replacement Considerations

Direct substitutes include other 70V05L series parts with identical pinouts and electrical characteristics but potentially different suffixes indicating package or temperature variations. Cross-reference tools should be used to identify parametrically equivalent components from the same manufacturer.
