72205LB25PFI8

Overview

The Renesas 72205LB25PFI8 is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-pin TQFP package (10x10mm) and is rated for industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Synchronous operation with programmable status flags for empty, half-full, and full conditions
• Unidirectional bus architecture designed for efficient data buffering
• Expandable depth and width capabilities for flexible system integration

Applications

• Multiprocessing systems requiring data synchronization
• Rate matching between asynchronous data streams
• Buffering applications in high-speed digital interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no damage to the 64-TQFP leads. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design implementation.

Selection Notes

Select this component when a synchronous FIFO with 18-bit word width and 256-word depth is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 15ns access time for timing constraints. Verify that unidirectional data flow meets the application's directionality needs without requiring bidirectional support.

Part Context

This part belongs to the IDT/Renesas 72205LB family of synchronous FIFOs. It shares functional compatibility with other members of the 7200 series, offering standardized interfaces for easy integration into existing designs. The 72205 variant specifically provides the 256x18 configuration, distinguishing it from deeper or narrower options in the lineup.

Replacement Considerations

The part is discontinued. Potential substitutes include the 72205LB25TFI or 72205LB25PFG, subject to availability and package compatibility verification.
