7140SA20PF

Overview

The Renesas Electronics Corporation 7140SA20PF is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access 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 surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports simultaneous independent read and write operations through two distinct port interfaces
• Provides high-speed asynchronous data transfer capabilities via parallel bus architecture
• Utilizes CMOS technology for low power consumption during active and standby modes

Applications

• High-performance digital signal processing systems requiring concurrent data access
• Telecommunications equipment utilizing fast buffer memory for packet handling
• Industrial control systems needing reliable volatile data storage for real-time operations

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as package variations exist within the 7140SA family. Confirm RoHS compliance status prior to integration, as specific variants may not meet current environmental directives. Check for end-of-life notifications or discontinuance notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for shared memory applications. Ensure the design accommodates the 4.5V to 5.5V supply voltage requirements. Verify that the 64-TQFP footprint matches the PCB layout constraints. Consider thermal management for the specified commercial temperature range if ambient conditions approach the upper limit.

Part Context

This part belongs to the IDT7140SA series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and package options to suit different system performance needs. These devices are designed for applications demanding high bandwidth and low latency memory solutions.

Replacement Considerations

Consult official substitution guides for compatible dual-port SRAMs with matching pinouts and electrical characteristics. Verify that any alternative device supports the same 1K x 8 organization and 20ns access speed.
