72255LA20TF8

Overview

The 72255LA20TF8 is an 8K x 18 SuperSync FIFO manufactured by Renesas Electronics. It operates at a core voltage of 5.0V with a bus width of 18 bits and supports I/O frequencies up to 50 MHz. The device features uni-directional architecture and is housed in a 64-pin LQFP package. It has a total density of 144 Kb and includes moisture sensitivity level 3 classification.

Feature Summary

• SuperSync technology for high-speed data buffering
• Uni-directional data flow architecture
• 5.0V logic operation compatibility

Applications

• High-speed data handling systems
• FPGA interface buffering
• Control system timing management

Procurement Notes

Verify the specific suffix TF8 indicates reel packaging when ordering. Confirm RoHS compliance status as documentation may vary. Ensure the 64-LQFP package matches your PCB footprint requirements. Check for any end-of-life notices or alternative part recommendations from Renesas before finalizing procurement plans.

Selection Notes

Select this component for applications requiring 18-bit wide data paths at 50 MHz speeds. The 5.0V supply requirement dictates compatible logic levels. Consider the 64-pin LQFP form factor for board space constraints. Verify that uni-directional flow meets the system's data transfer needs without needing bidirectional support.

Part Context

This part belongs to the Renesas SuperSync family of synchronous FIFOs. It is designed for high-performance memory buffering in digital systems. The 72255 series offers reliable data storage for synchronization between different clock domains or processing speeds.

Replacement Considerations

Check Renesas datasheets for direct pin-compatible replacements within the 72255 series. Verify if other SuperSync variants offer similar 18-bit widths with different access times or voltage requirements.
