72231L15PFGI

Overview

The Renesas 72231L15PFGI is a synchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates at a maximum data rate of 66.7 MHz and features a 10 ns access time. The component supports unidirectional bus direction and is supplied in a 32-TQFP package.

Feature Summary

• Synchronous first-in, first-out memory architecture for data buffering
• Supports single-clock or dual-clock operation modes
• Includes programmable full and empty flags for status monitoring

Applications

• Graphics data buffering
• Local area network interface buffering
• Interprocessor communication links

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any product change notices or end-of-life notifications that may affect long-term availability.

Selection Notes

Select this component when a 2K x 9 synchronous FIFO is required. Ensure the system voltage matches the specified supply range. Verify that the 32-pin TQFP package fits the PCB layout constraints. Consider if the 66.7 MHz speed meets the application timing requirements.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories. It is designed for high-speed data transfer applications requiring reliable buffering between asynchronous or synchronous domains. The 72231 variant specifically offers 18K bit depth.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics before considering any third-party equivalents.
