7203L20J

Overview

The Renesas Electronics Corporation 7203L20J is a discontinued asynchronous FIFO memory device belonging to the 7203 series. It features a storage organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The component operates with a maximum access time of 20 nanoseconds and supports a data rate up to 33.3 MHz. It functions on a single 5.0 V power supply, with an operating voltage range specified between 4.5 V and 5.5 V. The device utilizes a unidirectional bus architecture and is housed in a 32-lead PLCC package.

Feature Summary

Asynchronous operation for independent read and write clock domains
Unidirectional data transfer capability
CMOS technology construction

Applications

Data buffering in digital signal processing systems
Interface bridging between components with different clock speeds
Temporary data storage in high-speed logic circuits

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or secondary market sources. Verify RoHS compliance status, as original units may not meet current environmental standards. Confirm package integrity and moisture sensitivity handling requirements before procurement.

Selection Notes

Engineers should evaluate the 7203L12JG8 as a potential upgrade path due to its faster 12 ns access time within the same family. Consider pin compatibility and electrical parameter alignment when transitioning from this legacy part. Assess long-term supply chain stability given the discontinuation status and limited future availability.

Part Context

The 7203L20J is part of the broader 7203 series of asynchronous FIFOs produced by Renesas Electronics. This series provides various speed grades and packaging options for memory buffering applications. The specific model represents a mid-range performance option within the lineup, characterized by its 20 ns access time and standard 32-lead PLCC form factor.
