72104L50J

Overview

The Renesas Electronics Corporation 72104L50J is an asynchronous FIFO memory device featuring a storage capacity of 4K words by 9 bits. It operates with a maximum clock frequency of 15MHz and supports a data rate of 15MHz. The component has a typical access time of 50ns and functions within a supply voltage range of 4.5V to 5.5V. It utilizes a unidirectional bus architecture and is housed in a 44-pin PLCC package measuring 16.59mm by 16.59mm.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS technology implementation

Applications

• Data buffering between asynchronous systems
• Level shifting between different voltage domains
• Interface bridging in embedded control systems

Procurement Notes

Verify the specific suffix J against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as historical records may vary. Check current lifecycle status, as this component may be subject to discontinuation or obsolescence notices from the manufacturer.

Selection Notes

Select this part when a small-capacity, high-speed asynchronous buffer is required for 9-bit data paths. Ensure the system design accommodates the 44-pin PLCC footprint and the 4.5V to 5.5V power supply requirements. Consider the 50ns access time relative to the target system clock speeds.

Part Context

This component belongs to the Renesas 7200 series of FIFO memories, which are designed for general-purpose data storage and transfer applications. The 72104L50J specifically addresses needs for moderate depth buffering in parallel data interfaces, serving as a bridge between faster and slower logic sections in electronic circuits.

Replacement Considerations

Official substitutes include the IDT72104L50J. Verify pin compatibility and electrical specifications before substitution.
