7140SA100PF8

Overview

The Renesas Electronics Corporation 7140SA100PF8 is an 8Kbit dual-port asynchronous SRAM memory IC. It features a 1K x 8 memory organization and supports parallel interface communication. The device offers a maximum access time of 100 ns, ensuring efficient data retrieval for system applications. It operates within a supply voltage range of 4.5V to 5.5V and is designed for commercial temperature environments ranging from 0°C to +70°C. The component is housed in a 64-TQFP package with dimensions of 14x14 mm, facilitating surface-mount installation on printed circuit boards.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with various system clock speeds
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the specific suffix PF8 confirms the 64-TQFP package and 100ns speed grade against official Renesas documentation. Confirm RoHS compliance status as historical data may vary. Check for obsolescence notices or last-time-buy dates directly from the manufacturer before initiating procurement orders.

Selection Notes

Select this component when dual-port functionality is required for shared memory access between multiple masters. Ensure the 100ns access time meets the system timing requirements. Verify that the 64-TQFP footprint aligns with the PCB layout constraints and that the operating voltage range matches the target system power rails.

Part Context

This part belongs to the Renesas 7140SA series of dual-port SRAMs. It shares architectural similarities with other variants like the 7140SA55P but differs in package type and access speed. The series is designed for applications requiring high-speed data exchange between independent processing units without complex arbitration logic.

Replacement Considerations

Direct substitutes include the IDT7140SA100PF8. Verify pin compatibility and electrical specifications before substitution.
