70V05L55PF8

Memory IC Overview

The 70V05L55PF8 is a dual-port static random-access memory (SRAM) 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 an access time of 55 nanoseconds and a write cycle time of 55 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Supports independent simultaneous read and write operations at both Port A and Port B without bus contention.

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as packaging and compliance variations exist within the product family. Confirm that the specific lot date codes meet project requirements due to potential end-of-life status. Cross-reference pin assignments and electrical characteristics with the current datasheet to ensure compatibility with existing board designs before procurement.

Memory IC Selection Notes

Select this component when a moderate-speed dual-port SRAM with 64-kbit density is required for applications needing independent port access. Ensure the design accommodates the 3.0V to 3.6V supply voltage range and the 64-TQFP package dimensions. Consider thermal management within the specified commercial temperature range during system integration.
