72225LB15TF8

FIFOs Memory Overview

The Renesas Electronics Corporation 72225LB15TF8 is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 18K bits, organized as 1K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP package with dimensions of 10x10mm and functions reliably across an industrial temperature range of -40°C to 85°C.

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm moisture sensitivity level (MSL 3) requirements for storage and reflow soldering profiles. Ensure compatibility with existing PCB footprints for 64-TQFP packages. Check for RoHS compliance restrictions if applicable to target markets. Validate lead-free plating specifications against assembly equipment capabilities.

FIFOs Memory Selection Notes

Select this component when 18-bit wide data paths are required alongside high-speed synchronous operations up to 66.7MHz. Consider the 10ns access time for timing-critical applications. Evaluate the 64-TQFP package size constraints against available board space. Compare power consumption limits against thermal management capabilities. Assess programmable flag utility for flow control implementation needs.
