72245LB10TFI8

Overview

The Renesas 72245LB10TFI8 is a synchronous First-In, First-Out (FIFO) memory device with an organization of 4K x 18 bits. It operates on a single 5V supply voltage and supports data rates up to 100MHz with a typical access time of 6.5ns. The component features unidirectional bus architecture and is housed in a 64-pin Thin Quad Flat Package (TQFP). It includes programmable flags for status monitoring and is designed for industrial temperature ranges.

Feature Summary

• Synchronous FIFO architecture with independent read and write clock controls
• Programmable Almost-Empty and Almost-Full flags with default settings
• Output enable function places the output data bus in a high-impedance state
• Supports expansion in both depth and width

Applications

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

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as 'TF8' or 'TFI8' may indicate specific package or environmental certifications. Confirm current lifecycle status, as this series may be discontinued or subject to limited availability. Ensure compliance with RoHS directives if required by your manufacturing standards.

Selection Notes

Select this component when a 5V synchronous FIFO with 18-bit width is required. Compare against the 72V245 series if a 3.3V core voltage is necessary instead. Verify that the 64-pin TQFP package fits the board layout constraints. Check if the 100MHz speed requirement aligns with the system clock specifications.

Part Context

This part belongs to the Renesas 72245LB10 family of synchronous FIFOs. It is functionally related to the IDT72245LB10 series. The device serves as a data buffering solution for high-speed digital systems requiring reliable temporary storage between asynchronous or synchronous domains.

Replacement Considerations

The IDT72245LB10TFI8 is listed as an alias for this component. Verify pinout compatibility before substitution.
