72245LB15PF8

Overview

The Renesas Electronics Corporation 72245LB15PF8 is a synchronous First-In-First-Out (FIFO) memory device with an organization of 4K x 18 bits. It features a 10 ns access time and operates within a supply voltage range of 4.5 V to 5.5 V. The component supports bidirectional data buses and is housed in a 64-pin TQFP package. Designed for industrial applications, it functions reliably between 0°C and +70°C.

Feature Summary

• Synchronous FIFO architecture supporting dual-clock or single-clock operation
• Bidirectional 18-bit data bus interface
• Programmable status flags including full and empty indicators

Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) communication interfaces
• Interprocessor communication systems

Procurement Notes

Verify the exact suffix configuration against official datasheets, as packaging variations such as tray versus reel may exist within the series. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check for end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO with 10 ns speed is required. Ensure the design accommodates the 4.5 V to 5.5 V supply range and the 64-pin TQFP footprint. Verify that bidirectional bus requirements align with the specific pinout configuration provided in the technical documentation.

Part Context

This part belongs to the Renesas 72245 series of high-speed synchronous FIFOs. It shares architectural similarities with other members like the 72225 and 72235 but offers specific depth and width configurations. The series is designed for general-purpose data buffering in digital signal processing and communication applications.

Replacement Considerations

Check for direct substitutes within the 72245 family or compatible devices from other manufacturers offering identical pinouts and electrical characteristics. Verify functional equivalence regarding clocking schemes and flag outputs.
