70V05L35PF8

Memory IC Overview

The 70V05L35PF8 is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features an 8K x 8 organization, providing a total storage capacity of 64 kilobits. The device operates with a single 3.3V power supply and supports asynchronous parallel interfaces for both ports. It utilizes a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. The component offers a maximum access time of 35 nanoseconds and functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent read and write operations from either port without bus contention.
• Asynchronous operation allowing flexible timing control for both master and slave ports without clock synchronization requirements.
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate efficient data exchange between ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Network switch and router architectures utilizing dual-port RAM for packet processing queues.
• Industrial control systems needing isolated data sharing between separate processor domains.

Memory IC Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status, as this part number may be discontinued or subject to production changes. Ensure compatibility with 3.3V logic levels in the target circuit design before procurement.

Memory IC Selection Notes

Select this component when a 64Kbit dual-port SRAM with 35ns access speed is required. It is suitable for applications needing independent port access without external arbitration logic. Consider the 64-TQFP package constraints for PCB layout. Verify that the 3.3V operating voltage aligns with the system power rails and that the commercial temperature range meets environmental requirements.

Memory IC Part Context

This device belongs to the 70V05L series of dual-port SRAMs from Renesas Electronics. The series is designed for high-performance memory applications requiring fast, conflict-free data transfer between two processors or controllers. The 70V05L family typically includes variations with different access times and voltage supplies, such as 3.3V and 5V options.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for direct replacements. Verify pinout compatibility and electrical specifications if considering alternative manufacturers. Ensure any substitute part maintains the same 8K x 8 organization and dual-port functionality.
