72241L15PF

Overview

The Renesas Electronics Corporation 72241L15PF is a synchronous First-In, First-Out (FIFO) memory device organized as 4K x 9. It features a 10 ns access time and supports data rates up to 66.7 MHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 32-pin TQFP package. Designed for industrial applications, it functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Supports independent read and write clocks for dual-clock operation or single-clock synchronization
• Features zero fall-through time architecture for immediate data availability
• Includes programmable Almost-Empty and Almost-Full flags for flexible buffer management
• Provides output enable control to place the data bus in a high-impedance state

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as indicated by manufacturer documentation. Check for moisture sensitivity handling requirements during storage and assembly. Validate package integrity against the specified 32-TQFP form factor before integration into production lines.

Selection Notes

Select this component when a 4K x 9 synchronous FIFO with 10 ns speed is required. Ensure the design accommodates the 4.5 V to 5.5 V power supply range. Consider the 32-pin TQFP footprint for PCB layout constraints. Verify that the operating temperature range meets the specific environmental conditions of the target application system.

Part Context

This part belongs to the 72241 series of synchronous FIFOs from Renesas Electronics. It shares architectural similarities with other devices in the family but is distinguished by its specific 4K x 9 organization and 10 ns timing characteristics. The series is designed for high-speed data buffering tasks requiring reliable first-in, first-out memory management.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Renesas resources for current obsolescence notices and recommended alternative components if this part is discontinued.
