72245LB15TF

Overview

The Renesas Electronics Corporation 72245LB15TF is a synchronous first-in, first-out (FIFO) memory device belonging to the 72245 series. It features an organization of 4K x 18 bits and operates with a maximum access time of 10 ns. The component supports bidirectional data buses and functions within a supply voltage range of 4.5 V to 5.5 V. Designed for surface mount installation, it is housed in a 64-pin TQFP package. The device is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Synchronous FIFO architecture supporting dual-clock or single-clock operation
• Bidirectional data bus interface for flexible system integration
• Programmable status flags including empty, full, almost-empty, and almost-full indicators
• High-speed data buffering capability with 10 ns access time

Applications

• Optical disk controller data buffering
• Local Area Network (LAN) interface applications
• Interprocessor communication systems

Procurement Notes

Verify current availability as this component may be discontinued or subject to limited supply conditions. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure the specific suffix matches the required package type and temperature grade. Check for obsolescence notices or last-time buy notifications from the manufacturer.

Selection Notes

Select this part when a 4K x 18 synchronous FIFO with 10 ns speed is required. Compare against the 72V245 series if 3.3V operation is needed instead of 5V. Consider the 72845LB15PFI if dual independent FIFOs are necessary in a single package. Verify that the 64-pin TQFP package fits the board layout constraints.

Part Context

The 72245LB15TF belongs to the Renesas 72245 family of high-performance synchronous FIFOs. This series is designed for data buffering in high-speed digital systems. Related parts include variants with different access times and packages, such as the 72245LB10 series for faster speeds. The family supports expansion in both depth and width for custom memory configurations.

Replacement Considerations

Check for direct pin-compatible substitutes within the 72245 series. Verify electrical compatibility with similar synchronous FIFOs from other manufacturers. Ensure replacement parts meet the same 4.5V to 5.5V supply voltage and 10 ns access time specifications.
