72255LA10TFG

Overview

The Renesas Electronics Corporation 72255LA10TFG is a synchronous FIFO memory device with a storage capacity of 144K bits, organized as 8K words by 18 bits. It operates within a supply voltage range of 4 V to 5.5 V and supports data rates up to 100MHz with an access time of 8ns. The component utilizes a 64-TQFP package measuring 10x10 mm and features uni-directional bus architecture. It includes programmable flags and Full Water/Fill Threshold (FWFT) support for efficient data handling.

Feature Summary

• Uni-directional synchronous FIFO architecture with clocked read and write controls
• Programmable status flags and Full Water/Fill Threshold (FWFT) support
• Surface-mount installation in a compact 64-TQFP package

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between asynchronous logic domains
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix 'TFG' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes may indicate variations in packaging or lead finish. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates potential non-compliance for earlier variants in this series. Ensure the source document explicitly lists 72255LA10TFG as the active part number before procurement planning.

Selection Notes

Select this component when a synchronous interface with 18-bit width and 8K depth is required at 100MHz speeds. It is suitable for applications needing precise flow control via FWFT and programmable flags. Compare against the 72V255L15TF if lower voltage operation (3V-3.6V) is acceptable, noting that the 72255LA10TFG requires a higher 4V-5.5V supply.

Part Context

This device belongs to the Renesas SuperSync FIFO family, designed for high-performance memory buffering. It shares architectural similarities with other 722xx series parts but is distinguished by its specific 18-bit width and 100MHz speed rating. The TFG suffix denotes the specific tray-packaged TQFP variant offered by the manufacturer.
