70V05S55PF

Memory IC Overview

The 70V05S55PF is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 64Kb, organized as 8K words by 8 bits. The device operates with an asynchronous parallel interface and supports a voltage supply range of 3V to 3.6V. Key performance specifications include a maximum access time of 55 ns and a write cycle time of 55 ns per word/page. It is housed in a 64-TQFP package measuring 14x14 mm and is designed for surface mount installation. The component functions within a temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation providing flexible timing control without clock synchronization requirements
• Parallel interface supporting standard data bus connections for straightforward integration

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controller architectures
• Temporary storage in industrial automation control units

Memory IC Procurement Notes

Verify current availability status as this part may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that some sources indicate non-compliance. Ensure the 64-TQFP package dimensions match the target PCB footprint. Validate operating voltage ranges against system power rails before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations between two masters. Consider the 55 ns access speed for applications requiring moderate throughput. Evaluate the 64-TQFP package size against board space limitations. Compare against single-port alternatives if simultaneous access is not necessary to reduce cost.

Memory IC Part Context

This SRAM belongs to the 70V05 series, which focuses on low-voltage dual-port memory solutions. The series is designed for applications needing independent port access. The 70V05S55PF specifically targets systems requiring 64Kb capacity with asynchronous timing. It complements Renesas' broader portfolio of embedded memory products.

Memory IC Replacement Considerations

Check for official substitute part numbers from Renesas Electronics Corporation. Verify pin compatibility and electrical specifications before substitution. Review product discontinuance notices for end-of-life status.
