72241L10PFG8

Overview

The Renesas Electronics Corporation 72241L10PFG8 is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 4K words by 9 bits. It operates at a data rate of 100MHz with an access time of 6.5ns. The component supports unidirectional bus direction and functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 35mA. It is housed in a 32-TQFP package measuring 7x7mm and is rated for industrial temperatures from 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clock controls
• Programmable Almost-Empty and Almost-Full flags for status monitoring
• Dual-clock capability allowing asynchronous or single-clock modes
• Zero fall-through time architecture for immediate data availability

Applications

• Graphics data buffering
• Local area network communication
• Interprocessor communication

Procurement Notes

Verify the obsolete status and end-of-life notices before procurement planning. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements. Check for specific PCN updates regarding assembly sites or label changes. Ensure design-in compatibility with existing 32-pin TQFP footprints and 5V logic levels.

Selection Notes

Select this component for applications requiring 4K x 9 depth with 100MHz throughput. Consider the 32-TQFP package size constraints. Evaluate power consumption against the 35mA maximum specification. Verify that the 4.5V to 5.5V operating range matches the system power supply.

Part Context

This part belongs to the IDT 7200 series of synchronous FIFOs. It is functionally equivalent to two separate FIFO units integrated into a single package structure, though configured as a single unidirectional unit in this specific variant. The series is designed for high-speed data buffering in digital systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is marked as obsolete.
