72251L10PFGI8

Overview

The 72251L10PFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 73,728 bits organized as 8,192 words by 9 bits. The component operates with a maximum clock frequency of 100 MHz and supports a data rate of 100 MHz. Access time is specified at 6.5 ns with a cycle time of 10 ns. It functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 35 mA. The device is housed in a 32-pin LQFP package.

Feature Summary

• Synchronous operation for reliable data buffering between asynchronous systems
• Unidirectional bus direction supporting single-direction data flow
• Programmable flags for status monitoring and control
• Surface-mount installation type for automated assembly

Applications

• Data buffering in high-speed digital signal processing chains
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in communication protocol converters
• Clock domain crossing solutions in embedded systems

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation to ensure compatibility with required operating conditions and packaging standards. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or obsolescence announcements from the manufacturer before finalizing purchase orders.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 9-bit word width is required. Ensure the system operates within the 4.5 V to 5.5 V supply range. Verify that the 6.5 ns access time meets the timing requirements of the target application. Consider the 32-pin LQFP package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the IDT 722x1 series of synchronous FIFOs, originally developed by Integrated Device Technology and now produced by Renesas Electronics. The series is designed for high-performance data buffering applications requiring precise timing control. The 72251 variant specifically offers a 9-bit data path, distinguishing it from wider bus variants in the same family.
