72V231L15PFI

FIFOs Memory Overview

The 72V231L15PFI is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage capacity of 18K bits organized as 2K x 9. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and has a maximum supply current of 35mA. The device is housed in a 32-LQFP package with dimensions of 7x7mm and is rated for an operating temperature range of -40°C to 85°C.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with clocked read and write controls
• Supports single-clock or asynchronous dual-clock operation modes
• Includes programmable full and empty flags for status monitoring

FIFOs Memory Applications

• Graphics data buffering
• Local area network interfaces
• Interprocessor communication systems

FIFOs Memory Procurement Notes

Verify the End-of-Life (EOL) status before procurement, as this component may be discontinued. Confirm RoHS compliance requirements, as the part may not meet current environmental standards. Check for moisture sensitivity level (MSL 3) handling precautions during storage and assembly. Ensure availability through authorized distributors due to potential limited stock.

FIFOs Memory Selection Notes

Select this component for applications requiring reliable data buffering between asynchronous or synchronous domains. The 2K x 9 organization suits narrow data path interfaces. Consider the 10ns access time for high-speed processing needs. Verify that the 3.3V logic levels match the system voltage requirements. Evaluate the TQFP-32 package constraints against PCB layout space limitations.

FIFOs Memory Part Context

This part belongs to the 72V231 series of synchronous FIFO memories from Renesas. It serves as a 3.3V version of earlier devices like the 72231. The series is designed for general-purpose data buffering in digital systems. It shares architectural similarities with other members of the 72V family but differs in specific density and speed parameters.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72V231 series. Verify if alternative packages such as tape-and-reel versions are available for automated assembly. Compare electrical specifications to ensure compatibility with existing circuit designs.
