72225LB15TF

FIFOs Memory Overview

The Renesas Electronics Corporation 72225LB15TFI is a synchronous FIFO memory device with a storage capacity of 18K bits, organized as 1K words by 18 bits. It operates at a maximum data rate of 66.7MHz with an access time of 10ns. The component supports unidirectional bus direction and programmable flags. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. The device is housed in a 64-TQFP package (10x10mm) and supports surface mount installation. It is rated for an operating temperature range of -40°C to 85°C.

FIFOs Memory Procurement Notes

Verify the exact suffix designation, as the source material lists 72225LB15TFI, 72225LB15PFI, and 72225LB15PF8. Confirm RoHS compliance status, as some variants are marked non-compliant. Check moisture sensitivity level requirements for handling. Ensure the specific package dimensions match the design footprint. Validate end-of-life status before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 18K-bit synchronous FIFO with 18-bit width is required. Ensure the system voltage aligns with the 4.5V to 5.5V range. Verify that the 66.7MHz speed meets the application timing constraints. Consider the 64-pin TQFP package size for PCB layout compatibility. Compare against other members of the 7200 series if different depths or widths are needed.

FIFOs Memory Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other devices in the family, such as the 72235 and 72245 series, which offer different memory depths and speeds. The 72225 series specifically targets applications requiring moderate depth with wide data paths. It is distinct from the 72V211 series, which operates at lower voltages.
