72245LB25PF8

Overview

The Renesas 72245LB25PF8 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 at a maximum data rate of 100MHz with a typical access time of 6.5ns. The component supports unidirectional bus architecture and functions within a supply voltage range of 4.5V to 5.5V. It features programmable flags for status monitoring and is housed in a 68-pin PLCC package.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Programmable full and empty flags for accurate memory status indication
• Unidirectional data flow architecture simplifying interface design

Applications

• High-speed data buffering in communication systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix PF8 against official datasheets to confirm pinout and package dimensions. Confirm RoHS compliance status as legacy components may vary. Check for obsolescence notices or lifecycle changes from Renesas before finalizing procurement plans.

Selection Notes

Select this component when a 4K x 18 word depth is required for synchronous FIFO applications. Ensure the system operates within the 4.5V to 5.5V supply range. Verify that the 68-PLCC package fits the available PCB footprint and thermal requirements.

Part Context

This part belongs to the Renesas 72245 series of high-performance synchronous FIFOs. It is designed for applications requiring reliable data buffering between asynchronous or synchronous domains. The 18-bit width accommodates parity bits or extended data formats commonly used in industrial and communication protocols.

Replacement Considerations

Check for direct cross-references such as IDT72245LB25PF8. Verify electrical compatibility and pinout alignment before substitution.
