72T72105L5BB

FIFOs Memory Overview

The Renesas 72T72105L5BB is a high-performance First-In-First-Out (FIFO) memory device supporting both asynchronous and synchronous operation modes. It features a storage capacity of 4.5 Mbit, organized as 64K words by 72 bits. The component operates with unidirectional data flow and supports clock frequencies up to 83 MHz in asynchronous mode and 200 MHz in synchronous mode. Access times are specified at 10 ns for asynchronous and 3.6 ns for synchronous configurations. It functions within a supply voltage range of 2.375 V to 2.625 V and is housed in a 324-pin PBGA package measuring 19x19 mm.

FIFOs Memory Feature Summary

• Supports dual-mode operation for both asynchronous and synchronous timing requirements

FIFOs Memory Procurement Notes

Verify the specific suffix L5BB against official datasheets to confirm the 10ns/3.6ns timing variant. Confirm RoHS compliance status as documentation indicates non-compliance. Check for End-of-Life notifications or Product Change Notices affecting availability. Ensure the 324-PBGA package dimensions match the target PCB footprint. Validate moisture sensitivity level handling procedures during assembly.

FIFOs Memory Selection Notes

Select this component when a 72-bit wide FIFO is required for high-speed data transfer between different clock domains. Compare access times and power consumption against alternative models in the 72T series. Ensure the 2.5V supply voltage aligns with the system design. Verify that the 324-pin BGA package is compatible with the manufacturing capabilities. Consider the operational temperature range if used in industrial environments.

FIFOs Memory Part Context

This part belongs to the Renesas 72T series of FIFO memories, designed for high-performance data buffering. The series offers various capacities and bus widths to suit different application needs.
