72251L10PFGI

Overview

The Renesas 72251L10PFGI is an asynchronous and synchronous FIFO memory IC providing 8k x 9-bit storage capacity. It operates with a data rate of 100MHz and features a typical access time of 6.5ns. The device supports unidirectional data flow and functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 50mA. It is housed in a 32-TQFP package (7x7mm) and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports both asynchronous and synchronous operation modes for flexible system integration
• Provides high-speed data buffering with 100MHz data rate capability
• Features unidirectional data transfer architecture

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between components with different clock domains
• Temporary data storage in communication protocol converters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix PFGI matches the required 32-TQFP package and industrial temperature grade. Check for RoHS compliance documentation as indicated in official specifications. Ensure the obsolete status does not impact long-term supply requirements for your design lifecycle.

Selection Notes

Select this component when bidirectional FIFO functionality is not required, as it is strictly unidirectional. Compare against the 72251L10 series variants if different access times or package options are needed. Ensure the 8k x 9 organization fits the data width requirements of the application. Verify that the 6.5ns access time meets the timing constraints of the target system interface.

Part Context

This part belongs to the Renesas CMOS SyncFIFO family, designed for high-performance memory applications. The 72251L10 series offers various configurations including different data widths and organizations. The PFGI suffix specifically denotes the surface-mount TQFP package variant suitable for automated assembly processes in industrial environments.
