72251L10PFG

Overview

The 72251L10PFG is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics Corporation. It features a data organization of 8192 words by 9 bits, resulting in a total memory density of 73,728 bits. The component supports unidirectional data transfer with a maximum access time of 6.5 nanoseconds and an I/O frequency of 100 MHz. It operates within a supply voltage range of 3.0 V to 3.6 V and is housed in a 32-pin Thin Quad Flat Package (TQFP).

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering.
• High-speed interface supporting up to 100 MHz I/O frequency.
• Compact 32-pin TQFP surface-mount package design.

Applications

• Graphics data buffering systems.
• Local area network (LAN) communication interfaces.
• Interprocessor communication links.

Procurement Notes

Verify the specific suffix 'PFG' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the 32-pin TQFP package matches the target PCB footprint requirements. Ensure the 3.0 V to 3.6 V operating voltage aligns with the system power rails before integration.

Selection Notes

Select this component when a small-depth, narrow-width FIFO is required for high-speed synchronous data handling. The 9-bit width suits applications involving byte-aligned data with parity or control bits. The 100 MHz speed capability makes it suitable for modern bus architectures requiring low latency buffering between asynchronous or synchronous domains.

Part Context

This part belongs to the IDT SyncFIFO family, originally developed by Integrated Device Technology and now produced by Renesas Electronics. The 72251 variant specifically denotes the 8K x 9 configuration within the broader series of synchronous FIFO memories designed for general-purpose data storage and flow control applications.

Replacement Considerations

Cross-reference with other 8K x 9 synchronous FIFO devices from Renesas or compatible manufacturers. Verify electrical parameters such as access time, voltage range, and package dimensions to ensure functional equivalence without redesigning the host circuit board.
