70V05L35J8

Memory IC Overview

The Renesas Electronics Corporation 70V05L35J8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device supports parallel data interfaces with a maximum access time of 35 nanoseconds and operates within a supply voltage range of 3.0 volts to 3.6 volts. It is housed in a 68-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation. The component functions reliably across a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Asynchronous dual-port architecture enabling independent read/write operations on both ports
• Parallel interface supporting high-speed data transfer with 35ns access time
• Single power supply operation within the 3V to 3.6V range

Memory IC Applications

• Buffering applications in telecommunications systems

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this specific part number may not meet current environmental directives. Validate pin compatibility and electrical parameters before integration into existing designs to ensure operational reliability.

Memory IC Selection Notes

Select this component when a non-volatile-free, high-speed dual-port memory solution is required for buffering data between asynchronous domains. Consider the 64Kb capacity and 35ns speed as primary constraints. Evaluate the 68-PLCC package dimensions against available board space. Ensure the design accommodates the 3V to 3.6V operating voltage window and commercial temperature limits.

Memory IC Part Context

The 70V05L series represents Renesas' line of asynchronous dual-port SRAMs, offering flexible memory management for complex digital systems. This specific model provides a balance of density and speed suitable for mid-range embedded applications. The PLCC packaging facilitates easy prototyping and replacement in legacy designs while maintaining robust electrical performance standards typical of the family.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, alternative components must be evaluated based on functional equivalence, including matching access times, port configurations, and package footprints.
