72231L15PFG8

Overview

The Renesas Electronics Corporation 72231L15PFG8 is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 18K bits, organized as 2K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single 4.5V to 5.5V power supply with a maximum current consumption of 35mA. The device is housed in a 32-LQFP package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation for reliable data buffering between clock domains
• Expandable architecture allowing depth and width configuration
• Programmable status flags for empty, full, and half-full conditions

Applications

• Data buffering in high-speed digital signal processing systems
• Rate matching between asynchronous or different-speed logic blocks
• Interface bridging in telecommunications equipment

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm the tape-and-reel packaging format and lead-free RoHS compliance status. Ensure the order matches the exact 32-LQFP pinout and commercial temperature grade specifications required for the target application environment.

Selection Notes

Select this component when a synchronous FIFO with 9-bit word width and 2K depth is required. It is suitable for applications needing 10ns access times at 66.7MHz. Consider alternative series members if wider bus widths or higher speed grades are necessary for the system design.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, which are designed for multiprocessing and rate buffer applications. The series offers various configurations of depth and width, supporting both synchronous and asynchronous operations across different package types and temperature ranges.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference technical parameters such as access time, voltage range, and package dimensions before adopting any alternative components.
