72241L25PFI

Overview

The Renesas Electronics Corporation 72241L25PFI is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 4096 words by 9 bits. It features a maximum data rate of 40 MHz and an access time of 15 ns. The component operates on a single 5 V supply voltage ranging from 4.5 V to 5.5 V, with a maximum supply current of 35 mA. It utilizes a 32-pin TQFP package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports independent read and write clocks for dual-clock asynchronous operation or a single clock for synchronous mode.
• Features zero fall-through time architecture ensuring immediate data availability upon read enable.
• Includes programmable almost-empty and almost-full flags for flexible buffer management.

Applications

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

Procurement Notes

Verify the specific suffix 'PFI' against official Renesas documentation to confirm the exact pinout and package dimensions for the 32-pin TQFP variant. Confirm RoHS compliance status as historical records indicate non-compliance for some IDT/Renesas legacy parts. Validate lead times and end-of-life status through authorized distributors, as this component may be discontinued or subject to last-time buys.

Selection Notes

Select this component when a 9-bit wide synchronous FIFO is required for interfacing between asynchronous domains. Ensure the design accommodates the 5 V logic level requirements and the 32-pin TQFP footprint. Consider the 40 MHz maximum frequency limit relative to system clock speeds. Verify that the industrial temperature range meets environmental specifications.

Part Context

The 72241 series belongs to Renesas (formerly IDT) high-performance synchronous FIFO family. These devices are designed for high-speed data buffering applications requiring reliable first-in, first-out memory management. The 72241L25PFI specifically denotes the 15 ns speed grade within the L25 sub-series, packaged in a plastic quad flat pack.

Replacement Considerations

Check for direct cross-references such as IDT72241L25PFI. Evaluate alternative synchronous FIFOs with matching 4Kx9 depth and 5V operation if pin compatibility is critical.
