7140SA20PF8

Overview

The Renesas Electronics Corporation 7140SA20PF8 is an asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range from 0°C to 70°C. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports for high-throughput data handling.
• Utilizes CMOS technology to ensure low power consumption during operation.
• Features a parallel interface architecture for direct connection to microprocessors and digital signal processors.

Applications

• High-speed data buffering in telecommunications equipment
• Real-time processing systems requiring concurrent data access
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to limited availability. Confirm that the 64-TQFP package dimensions align with existing PCB footprints. Ensure that the 4.5V to 5.5V supply voltage requirement matches the target system design. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when dual-port functionality is required for simultaneous data access without bus contention. The 20 ns speed rating suits applications demanding rapid data throughput. Consider the 64-TQFP package for surface-mount assembly needs. Verify that the 8Kb capacity meets the specific memory organization requirements of the host system.

Part Context

This component belongs to the IDT7140SA/LA series of dual-port SRAMs manufactured by Renesas Electronics. The series is designed for applications requiring high-performance memory solutions with independent port access. The 7140SA20PF8 variant specifically denotes the 20 ns speed grade and the TQFP packaging option within this product family.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before replacing the component. Ensure that any alternative device maintains the dual-port architecture and 8Kb capacity requirements.
