7203L30TDB

Overview

The Renesas Electronics Corporation 7203L30TDB is an asynchronous FIFO memory device with a capacity of 18K bits, organized as 2K words by 9 bits. It features a unidirectional bus architecture and operates at a maximum data rate of 25MHz with a 30ns access time. The component supports a supply voltage range of 4.5V to 5.5V and utilizes CMOS parallel interface technology. It is housed in a 28-lead Ceramic Dual In-Line Package (CDIP-28).

Feature Summary

• Asynchronous operation for independent read and write clock domains.
• CMOS parallel interface supporting 9-bit wide data transfer.
• Unidirectional bus architecture for single-direction data flow.

Applications

• Data buffering in high-speed digital systems.
• Clock domain crossing interfaces.
• Parallel data storage applications.

Procurement Notes

Verify the specific manufacturer source, as this part number appears under both IDT and Renesas Electronics due to corporate acquisition history. Confirm package authenticity and lead integrity upon receipt. Check for RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability records for ceramic dual in-line packages.

Selection Notes

Select this component when a 2K x 9 asynchronous FIFO with 30ns speed is required. Consider the CDIP-28 package constraints for board layout. Verify that the 4.5V to 5.5V operating voltage aligns with system power rails. Evaluate thermal requirements for ceramic packaging in the intended environment.

Part Context

This device belongs to the 7203L series of asynchronous FIFOs. It shares architectural similarities with other members like the 7203L15 and 7203L20, differing primarily in speed grades and package types. The series is designed for reliable data buffering in industrial and communication equipment.

Replacement Considerations

IDT7203L30TDB is a confirmed substitute part number representing the same functional specifications and pinout compatibility.
