7204L20TP

Overview

The Renesas Electronics Corporation 7204L20TP is an asynchronous FIFO memory device with a storage capacity of 36K bits, organized as 4K words by 9 bits. It features a maximum data rate of 50MHz and an access time of 12ns. The component operates on a single supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 120mA. It utilizes a unidirectional bus direction and is housed in a 28-PDIP package.

Feature Summary

• Asynchronous operation for flexible clock domain interfacing
• Unidirectional data flow architecture
• Standard TTL-compatible logic levels

Applications

• Buffering data between different clock domains
• Interface bridging in digital systems
• Temporary data storage in high-speed processing chains

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or verifying specific stock conditions. Procurement should account for potential discontinuation risks and limited replacement options within the same series.

Selection Notes

Select this part when a small-capacity, unidirectional asynchronous FIFO is required for 9-bit wide data paths. Verify that the 12ns access time meets system timing requirements and that the 28-PDIP through-hole package fits the PCB layout constraints. Ensure the operating temperature range aligns with the application environment.

Part Context

The 7204L20TP belongs to the Renesas 7200 series of FIFO memories. This series provides various configurations for buffering applications. The 7204 variant specifically offers 4Kx9 organization, distinguishing it from other members like the 7206 which offers larger capacities. It serves as a legacy solution for older industrial and commercial designs requiring simple memory buffering.
