72241L10PFG

Overview

The Renesas 72241L10PFG is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It provides a storage capacity of 36K bits, organized as 4K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and features an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 35mA. The device is housed in a 32-TQFP package measuring 7x7mm and is designed for surface mount installation. It functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports dual-clock operation allowing independent read and write clocks or single-clock synchronization
• Features zero fall-through time architecture for immediate data availability upon read enable
• Includes programmable Almost-Empty and Almost-Full status flags for buffer management
• Provides Empty and Full flags to signal FIFO status conditions

Applications

• Graphics data buffering systems
• Local area network interface buffers
• Interprocessor communication links

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package integrity and pin alignment against the 32-TQFP specification. Check for moisture sensitivity handling requirements prior to assembly. Validate RoHS compliance documentation for regulatory adherence. Ensure replacement strategies are established given the obsolete product lifecycle.

Selection Notes

Select this component for applications requiring high-speed synchronous buffering with 9-bit data width. Consider the 100MHz performance limit and 6.5ns access time for timing constraints. Evaluate the 32-TQFP package suitability for PCB layout density. Verify power supply stability within the 4.5V to 5.5V range. Assess thermal management needs for the specified operating temperature range.
