72201L25PFG

Overview

The Renesas Electronics Corporation 72201L25PFG is a synchronous First-In, First-Out (FIFO) memory device belonging to the 72201 series. It features a storage organization of 256 words by 9 bits, providing a total capacity of 2.3 kilobits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7 MHz and an access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 32-pin TQFP package.

Feature Summary

• Synchronous FIFO architecture with dedicated read and write clocks for flexible dual-clock or single-clock operation
• Unidirectional bus interface designed for efficient data buffering applications
• Programmable status flags indicating full, empty, and almost-full conditions

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence. Confirm lead-free status and moisture sensitivity level prior to assembly. Check for RoHS compliance documentation as manufacturing standards may vary across production lots. Ensure proper ESD handling procedures are followed during procurement and storage.

Selection Notes

Select this component when a 256x9 synchronous FIFO is required for 5V logic systems. Compare against the 72201L10 variant if faster 10ns access times are needed. Consider the 72V201 series for 3.3V applications requiring lower power consumption. Verify package compatibility with existing PCB footprints before finalizing the design.

Part Context

This part belongs to the IDT 72201/72221/72241/72251 family of synchronous FIFOs manufactured by Renesas Electronics. These devices are widely used in high-speed digital systems requiring temporary data storage between asynchronous domains. The 72201 variant specifically offers 256-word depth, balancing cost and performance for moderate buffering needs.

Replacement Considerations

Direct pin-to-pin replacements include the 72201L10PFG for faster speed grades. For 3.3V equivalents, consider the 72V201 series. Verify that any substitute maintains the same 256x9 organization and TQFP-32 package dimensions.
