7204L50P

Overview

The Renesas Electronics Corporation 7204L50P is an asynchronous FIFO memory integrated circuit housed in a 28-pin PDIP package. It provides a storage capacity of 36K bits, organized as 4K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 15MHz and features a 50ns access time. It operates on a single 5V power supply ranging from 4.5V to 5.5V, drawing a maximum supply current of 120mA. Designed for industrial environments, it functions within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-port architecture enabling independent read and write clock domains
• Unidirectional data bus configuration for straightforward interface integration
• Standard CMOS technology ensuring reliable operation at 5V logic levels

Applications

• Buffering data streams between components operating at different clock speeds
• Interface bridging in telecommunications equipment requiring temporary data storage
• Data acquisition systems needing transient memory for signal processing

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package integrity upon receipt, as the PDIP format requires careful handling during soldering. Check manufacturing date codes against project requirements, noting that legacy stock may exhibit varying shelf life conditions. Ensure compatibility with existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this component when a small-capacity asynchronous FIFO is required for unidirectional data buffering. The 4Kx9 organization suits applications with narrow data buses. Consider the 50ns access speed adequate for moderate-frequency interfaces. Evaluate the PDIP package suitability for through-hole assembly processes versus surface-mount alternatives if space constraints exist.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories, originally developed under the IDT brand lineage. The 7204L50P specifically targets low-density memory needs within industrial and commercial electronic systems. Its design emphasizes simplicity and reliability for basic data buffering tasks without complex programmable flags or wide data paths.
