72T72115L6-7BB

FIFOs Memory Overview

The 72T72115L6-7BB is a high-performance asynchronous and synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 9M bits, organized as 128K words by 72 bits. The component supports data rates of 50MHz and 100MHz with corresponding access times of 14ns and 4.5ns. It operates on a supply voltage range of 2.375V to 2.625V and draws a maximum current of 130mA. The device is housed in a 324-pin PBGA package measuring 19x19mm and is designed for surface mount installation.

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate pin compatibility with existing PCB footprints before procurement. Review latest product discontinuance notifications for availability constraints.

FIFOs Memory Selection Notes

Select this FIFO for applications requiring wide 72-bit data paths and high throughput. Consider the specific timing requirements when choosing between 50MHz and 100MHz speed grades. Ensure power supply stability within the narrow 2.375V to 2.625V range. Evaluate thermal management needs given the 130mA maximum current consumption. Verify that the 324-PBGA package fits the available board space and manufacturing capabilities.
