72V245L20PF8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V245L20PF8 is a synchronous FIFO memory device with a storage capacity of 72K bits, organized as 4K words by 18 bits. It operates on a single 3.3V supply voltage ranging from 3V to 3.6V and supports a maximum data rate of 50MHz with an access time of 12ns. The component features unidirectional bus directionality and is housed in a 64-TQFP package measuring 14x14mm. It functions within a commercial temperature range of 0°C to 70°C and draws a maximum supply current of 30mA.

FIFOs Memory Feature Summary

• Synchronous first-in, first-out (FIFO) architecture supporting dual-clock operation for independent read and write cycles or single-clock mode.
• Programmable status flags including First Word Fall Through (FWFT), empty, full, and optional almost-empty/almost-full indicators.
• High-speed data buffering capability designed for interprocessor communication and network interface applications.

FIFOs Memory Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) interface modules
• Interprocessor communication systems

FIFOs Memory Procurement Notes

Verify the specific suffix '8' against official manufacturer documentation, as standard listings often reference the 'PF' variant without this suffix. Confirm RoHS compliance status, as some variants in this series are marked non-compliant. Check for End-of-Life notices, as similar models in the 72V245 family have been discontinued. Ensure the 64-TQFP package dimensions match your PCB footprint requirements before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide synchronous FIFO buffer is required for 3.3V logic systems. Compare against the 72V245L10PFG8 if higher speed (100MHz) is needed, or the 72V245L15TFGI if industrial temperature ratings (-40°C to +85°C) are necessary. Verify that the 12ns access time meets your system timing constraints and that the unidirectional data flow aligns with your circuit design.

FIFOs Memory Part Context

The 72V245L20PF8 belongs to the Renesas 72V series of high-performance synchronous FIFO memories. This series is engineered for 3.3V applications, offering a modern alternative to older 5V devices while maintaining compatibility with various digital signal processing and networking architectures. The 72V245 model specifically provides a 4K x 18 configuration suitable for medium-depth buffering tasks.
