7140SA100CB

Overview

The Renesas Electronics Corporation 7140SA100CB is an asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 8 kbit, organized as 1K x 8 words. The component features a parallel interface with a maximum access time of 100 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power current of 110 mA. The device is housed in a 48-SIDE BRAZED package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring dual-processor access

Procurement Notes

Verify the obsolete status and end-of-life designation before procurement planning. Confirm RoHS compliance requirements against specific project standards, as this component may not meet current environmental directives. Validate that the 48-SIDE BRAZED package is compatible with existing assembly processes and thermal management strategies. Ensure supply chain stability due to discontinued manufacturing status.

Selection Notes

Select this component when dual-port memory functionality is required for asynchronous data sharing between multiple masters. The 100 ns access time suits moderate-speed logic applications. Consider the 48-SIDE BRAZED package constraints for board layout and mounting. Evaluate alternative components if RoHS compliance or active lifecycle status is mandatory for the design.

Part Context

This part belongs to the 7140 series of dual-port SRAMs from Renesas Electronics. It shares architectural similarities with variants like the 7140LA100CB and 7140SA55CB, differing primarily in access speed and package type. The series is designed for applications requiring high-reliability memory with independent port control.

Replacement Considerations

Public confirmed substitute part numbers include IDT7140SA100CB.
