70V05L55PFG8

Memory IC Overview

The 70V05L55PFG8 is a 64-kbit (8K x 8) dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The device features an asynchronous parallel interface with a maximum access time of 55 ns. It is housed in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm and supports surface-mount installation. The component is rated for commercial operating temperatures between 0°C and +70°C.

Memory IC Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports asynchronous operation without external clock requirements
• Utilizes low-voltage CMOS technology for reduced power consumption

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in digital signal processing

Memory IC Procurement Notes

Verify the specific suffix 'G8' indicates reel packaging, as this differs from tray-packaged variants like the standard PFG. Confirm RoHS compliance status for the specific manufacturing lot, as older production runs may not meet current environmental directives. Ensure the receiving facility handles moisture-sensitive devices according to JESD22-A114 standards prior to soldering.

Memory IC Selection Notes

Select this component when independent dual-port access is required for 8-bit wide data paths. The 55 ns speed class suits moderate-frequency asynchronous interfaces where lower cost is prioritized over high-speed performance. Verify that the 64-TQFP footprint matches the target PCB layout constraints and thermal dissipation requirements for the application environment.

Memory IC Part Context

This part belongs to the 70V05L series of low-power dual-port SRAMs. It shares architectural similarities with other members like the 70V05L15 but offers slower access speeds. The 'G8' suffix specifically denotes tape-and-reel packaging, distinguishing it from tray-packaged equivalents such as the 70V05L55PF or 70V05L55PFG.

Memory IC Replacement Considerations

The 70V05L15PFG is listed as an upgrade alternative. Verify pin compatibility and timing differences when substituting faster variants. Check for package equivalence if replacing tray-packaged versions with reel-packaged units.
