72V245L10TFI

FIFOs Memory Overview

The Renesas Electronics Corporation 72V245L10TFI is a synchronous first-in, first-out (FIFO) memory device belonging to the 72V245 series. It features an organization of 4K x 18 bits, providing a total storage capacity of 72 kbit. The component operates with a unidirectional bus and supports a maximum clock frequency of 66.7 MHz, achieving an access time of 10 ns. It functions within a supply voltage range of 3 V to 3.6 V, with a maximum power consumption of 30 mA. The device is housed in a TQFP-64 package and is rated for industrial operating temperatures between -40°C and +85°C.

FIFOs Memory Feature Summary

• Supports both asynchronous and coincident read/write clock operations for flexible data buffering.
• Includes programmable almost-empty and almost-full flags alongside standard empty and full status indicators.
• Features output enable functionality that places the output data bus into a high-impedance state.

FIFOs Memory Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication

FIFOs Memory Procurement Notes

Verify the specific suffix 'TFI' against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level. Confirm current lifecycle status as the 72V245 series has faced end-of-life notices for certain variants. Ensure design-in compliance with RoHS directives and check for any product change notifications affecting assembly sites or labeling.

FIFOs Memory Selection Notes

Select this component when a 3.3V synchronous FIFO with 18-bit width is required for moderate-speed data buffering. Compare against the 72V245L10PFG8 variant if tape-and-reel packaging is preferred over trays. Consider the 72V291 series if 9-bit width or different latency characteristics better suit the system architecture.

FIFOs Memory Part Context

The 72V245L10TFI is part of the broader 72V2x5 family of SuperSync FIFOs manufactured by Renesas Electronics. This family provides 3.3V versions of legacy 5V devices, maintaining functional compatibility while reducing power consumption. The 72V245 specifically targets applications requiring 18-bit data paths, distinguishing it from other members like the 72V241 or 72V243 which offer different word widths.
