7202LA25TPI

Overview

The Renesas 7202LA25TPI is a 1K x 9 asynchronous FIFO memory device operating at a maximum data rate of 25MHz with a 30ns access time. It features a unidirectional bus architecture and supports relay capability for signal buffering. The component operates within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 100mA. It is housed in a 28-pin PDIP package and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Asynchronous first-in-first-out memory architecture for temporary data storage
• Unidirectional bus directionality for sequential data flow management
• Relay capability enabling signal buffering and timing adjustment
• Standard TTL interface compatibility for 5.0V logic systems

Applications

• Data buffering between asynchronous clock domains
• Interface bridging for high-speed digital communication links
• Temporary data storage in embedded processing systems
• Signal timing adjustment in industrial control circuits

Procurement Notes

Verify the specific suffix TPI confirms the 28-pin PDIP package configuration. Confirm RoHS compliance status as legacy variants may differ. Check for active production or obsolescence notices from Renesas. Ensure the supplier provides valid traceability documentation for this discontinued component series.

Selection Notes

Select this part when a 1K x 9 depth and 9-bit width are required for unidirectional data transfer. The 25MHz speed rating suits moderate-frequency applications. Verify that the PDIP package fits the target PCB footprint. Consider the -40°C to 85°C temperature range against environmental requirements.

Part Context

This component belongs to the Renesas 7202L family of asynchronous FIFOs. It shares architectural similarities with other members like the 7202LA15TPI but offers different speed grades. The 7202 series is designed for general-purpose memory buffering in digital logic applications.
