72235LB15PF

Overview

The Renesas 72235LB15PF is a synchronous FIFO memory device with a capacity of 36K bits, organized as 2K words by 18 bits. It supports unidirectional data transfer at a maximum clock frequency of 66.7MHz with a 10ns access time. The component operates on a single 4.5V to 5.5V power supply and draws a maximum current of 60mA. It features programmable flags for status monitoring and is housed in a 64-pin TQFP package.

Feature Summary

• Synchronous operation with dedicated read and write clocks for reliable data synchronization across different domains
• Programmable flag outputs provide customizable status indication for full, empty, and near-full conditions
• Unidirectional bus architecture simplifies interface design for specific data flow requirements

Applications

• Data buffering between asynchronous logic blocks
• Clock domain crossing interfaces
• High-speed data acquisition systems

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as PFI or TF8 may indicate differences in packaging or moisture sensitivity levels. Confirm RoHS compliance status and lead times through authorized distributors, as availability varies by region and production lifecycle stage.

Selection Notes

Select this component when a 2K x 18 word depth is required for synchronous buffering applications. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 64-pin TQFP footprint for PCB layout constraints and verify that the 66.7MHz speed meets the target data throughput requirements.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs. The series offers various capacities and speeds to support diverse digital signal processing and communication needs. The 72235 variant specifically targets applications requiring moderate depth with fast access times.

Replacement Considerations

Check for direct substitutes within the same series, such as the 72235LB15PFI or 72235LB15TF8, which share identical electrical characteristics but differ in packaging type. Verify pin compatibility and thermal requirements before substitution.
