72245LB10PF

Overview

The Renesas Electronics Corporation 72245LB10PF is a synchronous FIFO memory device featuring an organization of 4K x 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 100 MHz with a typical access time of 6.5 ns. The component utilizes a 64-pin TQFP package and is designed for unidirectional data buffering applications.

Feature Summary

• Synchronous first-in, first-out architecture with clocked read and write controls
• Supports single-clock or asynchronous dual-clock operation modes
• Includes programmable flags for full, empty, almost-full, and almost-empty states

Applications

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

Procurement Notes

Verify the specific suffix 'PF' against official documentation to confirm the 64-pin TQFP package configuration. Confirm RoHS compliance status as sources indicate potential non-compliance. Check moisture sensitivity level requirements before handling. Validate lead-free status if required by assembly specifications.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO is required for 5V logic interfaces. Ensure the design accommodates the 64-pin TQFP footprint. Verify that the 100 MHz speed meets system timing constraints. Consider the 72V245 series if a 3.3V operating voltage is necessary instead.

Part Context

This part belongs to the IDT 72245L family of high-speed synchronous FIFOs. It serves as a standard solution for bridging data transfer rates between different clock domains. The device provides reliable buffering for digital signal processing and communication protocols requiring precise data sequencing.

Replacement Considerations

The 72V245L10PFG is a verified alternative offering identical functionality but operating at 3.3V. Other members of the 72245L family may provide compatible pinouts or performance characteristics depending on specific voltage and package requirements.
