70V05L20PFG8

Memory IC Overview

The 70V05L20PFG8 is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device features asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates on a single 3-volt to 3.6-volt power supply and supports surface-mount installation in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters. The component functions within an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic power-down mode controlled by chip enable signals

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring concurrent port access

Memory IC Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement components. Ensure that any substitute parts maintain compatibility with the original voltage, package, and timing specifications required by the design.

Memory IC Selection Notes

Engineers should evaluate the 70V05L20PFG8 for designs requiring dual-port memory with 20-nanosecond access speeds. Consider the 64-pin TQFP footprint and 3.3-volt operation limits during schematic capture. Verify that the selected component meets the thermal requirements for the intended operating environment before finalizing the bill of materials.

Memory IC Part Context
