7142SA100CB

Overview

The 7142SA100CB is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features an asynchronous parallel interface with a storage capacity of 16Kb, organized as 2K words by 8 bits. The device supports a supply voltage range of 4.5V to 5.5V and operates within a commercial temperature range of 0°C to 70°C. It utilizes a 48-side brazed DIP package designed for through-hole mounting. The component specifies a maximum access time and write cycle time of 100 ns.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations on separate ports
• Asynchronous parallel interface supporting standard logic levels
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering in industrial control systems
• Real-time signal processing applications requiring concurrent data access
• Embedded systems utilizing legacy through-hole PCB designs

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as variations may indicate differences in packaging or testing criteria. Confirm RoHS compliance status prior to integration, as older variants often lack modern environmental certifications. Ensure compatibility with existing system voltage requirements and thermal management strategies during procurement planning.

Selection Notes

Select this component when a dual-port memory solution with through-hole mounting is required for legacy hardware maintenance. Compare access speeds and pin configurations against alternative SRAM families if newer form factors are acceptable. Evaluate total cost of ownership considering potential obsolescence risks associated with discontinued semiconductor products.

Part Context

This part belongs to the 7142SA series of dual-port SRAMs from Renesas Electronics. The series typically offers various speed grades and package options to accommodate different design constraints. The 7142SA100CB represents a specific configuration within this lineage, characterized by its 100 ns speed rating and specialized ceramic DIP packaging suitable for high-reliability environments.

Replacement Considerations

Consult official discontinuation notices for approved substitute part numbers. Verify electrical pinouts and timing parameters before substituting with other dual-port SRAM models. Cross-reference with current Renesas product portfolios for modern equivalents if redesigning the application.
