72245LBTFI8

Overview

The Renesas Electronics Corporation 72245LBTFI8 is a synchronous First-In-First-Out (FIFO) memory device with a storage capacity of 72K bits, organized as 4K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 100 MHz with an access time of 6.5 ns. The component features unidirectional bus directionality and programmable flag support. It is housed in a 64-pin Thin Quad Flat Package (TQFP) and is designed for surface-mount installation.

Feature Summary

• Synchronous FIFO architecture supporting single-clock or dual-clock operation
• Programmable status flags for monitoring buffer levels
• High-speed data buffering capability up to 100 MHz

Applications

• Optical disk controllers
• Local Area Network (LAN) interfaces
• Interprocessor communication systems

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the product family. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check current availability as this specific part number may be subject to discontinuation notices or limited stock conditions from authorized distributors.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO is required for high-speed data buffering applications. Ensure the system design accommodates the 4.5 V to 5.5 V operating voltage range and the 64-pin TQFP package constraints. Verify that the 100 MHz performance meets the timing requirements of the target interface.

Part Context

This device belongs to the 72245LB series of synchronous FIFOs manufactured by Renesas Electronics. It serves as a specialized memory solution for buffering data streams between asynchronous or synchronous digital systems. The 72K bit density provides substantial buffering depth for wide data buses.

Replacement Considerations

The IDT72245LB10TF8 is listed as an alias for this part number. Verify functional equivalence and pin compatibility before substitution.
