7050S35G

Memory IC Overview

The Renesas Electronics Corporation 7050S35G is a static random access memory (SRAM) component belonging to the 7050 series. It features a storage capacity of 1K x 8 bits and utilizes a four-port architecture for asynchronous parallel data transfer. The device operates within a supply voltage range of 4.5V to 5.5V and supports an access time of 35ns. It is housed in a PGA-108 package and is designated as Not Recommended for New Designs, with official documentation recommending the 7052 series as a replacement.

Memory IC Feature Summary

• Four-port architecture enabling simultaneous independent read and write operations across multiple ports
• Asynchronous parallel interface supporting standard SRAM control signals
• Static RAM technology providing non-volatile retention characteristics when powered

Memory IC Applications

• High-speed data buffering in legacy industrial control systems
• Cache memory implementation in older embedded processor designs
• Data storage in telecommunications equipment requiring multi-port access

Memory IC Procurement Notes

This component is officially marked as Not Recommended for New Designs. Verify current availability through authorized distributors, noting potential end-of-life status. Confirm package integrity and authenticity upon receipt. Review the manufacturer's discontinuation notices for timeline details. Ensure design migration plans align with the recommended 7052 series transition if applicable.

Memory IC Selection Notes

Select this part only for maintenance or repair of existing equipment utilizing the 7050 series. Evaluate the 7052 series for new projects due to improved performance and support. Compare pin compatibility and electrical specifications against system requirements. Assess long-term supply stability given the discontinued status. Consult official datasheets for detailed timing parameters.

Memory IC Part Context

The 7050 series represents an earlier generation of high-performance SRAMs from Renesas Electronics. These devices were designed for applications requiring fast access times and flexible port configurations. The 7050S35G specifically offers a compact 1K x 8 configuration in a PGA-108 package. This series has been largely superseded by newer generations offering higher densities and enhanced features.

Memory IC Replacement Considerations

Official documentation explicitly recommends the 7052 series as the successor. Verify pinout compatibility between the 7050 and 7052 families before substitution. Check for differences in power consumption and access speeds. Ensure the replacement meets all original system timing and voltage requirements.
