72V291L15PF8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V291L15PF8 is a synchronous FIFO memory device featuring a storage capacity of 1.125M bits, organized as 128K words by 9 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The component supports unidirectional bus direction and functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 80mA. It is housed in a 64-TQFP package measuring 14x14 mm and is rated for an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) functionality for rapid data availability.
• Includes programmable flags and relay capability for flexible interface control.
• Enables depth and width expansion for system scalability.

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic domains
• Data acquisition systems requiring temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm pinout and packaging dimensions, as variations exist within the 72V series. Confirm RoHS compliance status, as some variants in this family are non-compliant. Check for end-of-life notices or obsolescence warnings prior to procurement, as availability may be restricted.

FIFOs Memory Selection Notes

Select this component when a 128K x 9 synchronous FIFO with 10ns access time is required. Ensure the system power supply aligns with the 4.5 V to 5.5 V operating range. Consider the 64-TQFP package size for PCB layout constraints. Verify that unidirectional data flow meets the application requirements compared to bidirectional alternatives.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of SuperSync FIFOs, designed for high-performance memory applications. It shares architectural similarities with other members like the 72V291L15TF but differs in packaging and voltage specifications. The series is characterized by low power consumption and high-speed operation suitable for complex digital designs.
