72245LB10PFG

Overview

The Renesas Electronics Corporation 72245LB10PFG is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It features a storage capacity of 72K bits organized as 4K words by 18 bits per word. The component supports unidirectional data transfer with a maximum operating frequency of 100 MHz and an access time of 6.5 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. The device is housed in a 64-pin Thin Quad Flat Pack (TQFP) package measuring 14 mm by 14 mm. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous FIFO architecture supporting single-clock or dual-clock operation modes
• Programmable status flags including empty, full, almost-empty, and almost-full indicators
• Easily expandable memory depth and width capabilities for system integration
• Output enable control to place the data bus in a high-impedance state

Applications

• Optical disk controller data buffering
• Local Area Network (LAN) interface applications
• Interprocessor communication systems

Procurement Notes

Verify part authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices or lifecycle changes that may affect long-term availability. Ensure proper handling procedures are followed given the surface-mount packaging type.

Selection Notes

Select this component for designs requiring reliable synchronous data buffering between asynchronous logic domains. Consider the 18-bit bus width and 4K depth when sizing buffers for specific throughput requirements. Evaluate the 6.5 ns access speed against system clock constraints. Verify compatibility with 5V logic levels and ensure adequate thermal management for the TQFP package.

Part Context

The 72245LB10PFG is part of the Renesas 7200 series of high-performance FIFO memories. This series provides versatile buffering solutions for various digital signal processing and communication applications. The PFG suffix indicates the specific 64-pin TQFP package variant suitable for surface-mount technology assembly processes.
