7202LA12TPI

Overview

The Renesas Electronics Corporation 7202LA12TPI is an asynchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports unidirectional data bus direction and operates with a maximum data rate of 50MHz. Access time is specified at 12ns. It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 80mA. The device is housed in a 28-PDIP (0.300 inch) package and is rated for operation between 0°C and 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Supports retransmit capability to ensure data integrity during bus contention or error conditions.
• Unidirectional data flow simplifies system design for specific buffer applications.

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock speeds
• Temporary storage in communication protocol converters

Procurement Notes

Verify the exact suffix 'TPI' against official Renesas documentation to confirm pinout and electrical specifications, as variations exist within the 7202L family. Ensure compatibility with standard 28-pin DIP footprints. Check RoHS compliance status for the specific manufacturing batch. Confirm availability through authorized distributors given potential lead times associated with legacy logic families.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO with 12ns access time is required in a through-hole package. Compare against the JG variant if surface mount assembly is preferred. Consider the LA12 speed grade relative to system timing requirements. Verify that the 9-bit width meets data bus alignment needs without additional padding logic.

Part Context

This part belongs to the Renesas 7202L series of CMOS parallel FIFOs, originally developed by IDT before acquisition. The series offers various speed grades and packaging options to support diverse embedded memory applications. The 7202LA12TPI specifically targets designs requiring reliable asynchronous buffering in dual-in-line packages.

Replacement Considerations

The IDT7202LA12TP is a direct equivalent from Integrated Device Technology. Other 7202L variants with different suffixes may offer alternative packaging but require verification of mechanical fit and electrical equivalence.
