7205L15TPGI

Overview

The Renesas 7205L15TPGI is an asynchronous FIFO memory integrated circuit housed in a 28-PDIP package. It provides a storage capacity of 72K bits, organized as 8K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The component is rated for industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Unidirectional data flow simplifies system design for specific buffer applications.
• Industrial temperature rating ensures reliable performance in demanding environmental conditions.

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the part status carefully as this component is scheduled for obsolescence and discontinuation by the manufacturer. Confirm availability through authorized distributors or remaining stock holders. Ensure that any substitute components maintain compatibility with the existing 28-PDIP footprint and electrical specifications to avoid redesign efforts.

Selection Notes

Select this component when a small-to-medium depth asynchronous FIFO is required for unidirectional data buffering. The 8K x 9 configuration suits applications needing moderate latency tolerance. Verify that the 15ns access time meets the system timing requirements. Consider the PDIP package constraints if surface-mount solutions are preferred for future manufacturing.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs, which are designed for general-purpose data buffering. The series offers various capacities and speed grades to accommodate different system bandwidth needs. These devices are commonly used in legacy and modern digital designs requiring reliable data synchronization between asynchronous domains.

Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as the 7205L50P for slower speed requirements. Verify that alternative parts support the same 8K x 9 depth and unidirectional functionality. Ensure the replacement maintains the 28-PDIP package form factor for board compatibility.
