72245LB15TF8

Overview

The Renesas 72245LB15TF8 is a synchronous First-In-First-Out (FIFO) memory device with a capacity of 72K bits, organized as 4K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 66.7 MHz with a maximum access time of 10 ns. The component utilizes a 64-pin TQFP package and features unidirectional bus architecture. It includes programmable flags for status monitoring and is designed for industrial temperature ranges.

Feature Summary

• Synchronous FIFO architecture supporting single-clock or asynchronous dual-clock operation
• Programmable flag support for empty, full, and almost-empty/full conditions
• Unidirectional data bus with 18-bit width for efficient data buffering
• Industrial temperature range capability for robust environmental performance

Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication systems

Procurement Notes

Verify end-of-life status and obsolescence notices before procurement. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing 5V logic interfaces and check for available replacement components from the manufacturer's official documentation.

Selection Notes

Select this component for applications requiring reliable synchronous data buffering between devices operating at different clock domains. Consider the 18-bit word width and 4K depth for appropriate buffer sizing. Verify that the 64-pin TQFP package fits the board layout constraints and thermal requirements of the target system design.

Part Context

This part belongs to the Renesas 72245 series of high-speed synchronous FIFO memories. It is functionally similar to other variants in the 722x5 family but differs in speed grade and package type. The LB suffix typically denotes specific speed and package characteristics within the product line.

Replacement Considerations

Check for direct pin-compatible replacements such as the 72245L10TF8 or 72245L15TFI if availability permits. Verify electrical parameter equivalence, particularly access time and supply voltage, when substituting with other members of the 72245 series.
