72235LB25PFI

Overview

The Renesas 72235LB25PFI is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates at a maximum data rate of 40MHz with a 15ns access time. The component supports unidirectional bus direction and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 60mA. The device is housed in a 64-TQFP (14x14) surface-mount package and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with configurable depth and width expansion capabilities
• Programmable full and empty flag outputs for buffer management
• Unidirectional data transfer architecture

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm the exact package type and tape/reel specifications. Confirm RoHS compliance status, as historical variants may differ. Check for End-of-Life notices or obsolescence warnings prior to procurement, as availability may be restricted. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this component when a 2K x 18 word synchronous FIFO is required with 40MHz performance. Consider the 64-pin TQFP package constraints for PCB layout. Evaluate if the 15ns access time meets system timing requirements. Compare against other members of the 7200 series for alternative capacities or speeds if the specific 36K configuration is not mandatory.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs. The series offers various configurations in terms of word count and bit width. The 72235 variant specifically provides 36K bits of storage. These devices are designed for applications requiring reliable data buffering and protocol conversion between different speed domains in digital systems.

Replacement Considerations
