72255L20PF

Overview

The Renesas 72255L20PF is a synchronous FIFO memory device with a capacity of 144K bits, organized as 8K words by 18 bits. It operates at a maximum data rate of 50MHz with a typical access time of 12ns. The component supports unidirectional data transfer and functions within a supply voltage range of 4.5V to 5.5V. It is housed in a 64-TQFP package (14x14mm) and is rated for commercial operating temperatures from 0°C to +70°C.

Feature Summary

• Synchronous first-in-first-out buffering architecture
• Unidirectional data flow capability
• High-speed operation up to 50MHz

Applications

• Data buffering between asynchronous system domains
• Interface bridging in high-speed digital circuits
• Temporary storage in communication protocols

Procurement Notes

Verify current product status as the component may be obsolete or discontinued. Confirm availability through authorized distributors or direct manufacturer channels. Check for moisture sensitivity levels and handling requirements prior to procurement. Ensure compatibility with existing design specifications before finalizing orders.

Selection Notes

Select this part for applications requiring reliable synchronous buffering with unidirectional data paths. Consider the 18-bit word width and 8K depth for specific buffer size needs. Evaluate the 64-TQFP package constraints against board space limitations. Verify that the 50MHz speed meets system timing requirements.

Part Context

This component belongs to the Renesas 722xx5LB series of synchronous FIFOs. It shares architectural similarities with other parts in the family but offers specific capacity and speed characteristics tailored for moderate-speed data buffering applications.
