70V05L55PF

Memory IC Overview

The 70V05L55PF is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device operates with an asynchronous parallel interface and has a maximum access time of 55 nanoseconds. It supports a supply voltage range from 3 volts to 3.6 volts. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 millimeters. It is designed for surface mount installation and functions within an ambient temperature range of 0°C to +70°C.

Memory IC Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors for remaining stock or consider approved upgrade alternatives. Ensure that the 64-TQFP package footprint matches the design requirements. Check for moisture sensitivity level compliance during handling and storage to prevent damage prior to soldering.

Memory IC Selection Notes

Select this component only if the specific 55 ns access speed and 64-kbit capacity align with system timing constraints. Verify that the 3V to 3.6V operating voltage range matches the target power supply rails. Consider the 64-TQFP package size for board space limitations. Evaluate whether the asynchronous parallel interface meets the bus requirements of the host processor. Assess end-of-life implications for long-term production viability.

Memory IC Part Context

This device belongs to the 70V05L series of dual-port SRAMs from Renesas Electronics. These components are engineered for applications requiring fast, independent data access from two separate ports. The series typically offers various speed grades and packaging options to suit different performance and form factor needs. The 70V05L55PF represents a specific speed grade within this family, providing a balance of performance and pin count for general-purpose memory applications.

Memory IC Replacement Considerations

The 70V05L15PFG is identified as an upgrade alternative. This replacement offers a faster 15 ns access time while maintaining the same 64-kbit capacity and 64-TQFP package. Verify electrical compatibility and signal integrity when transitioning to the higher-speed variant.
