72V251L20PFGI

FIFOs Memory Overview

The 72V251L20PFGI is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features an organization of 8K x 9 bits, providing a total storage capacity of 72 kilobits. The component operates with a maximum access time of 20 nanoseconds and supports data rates up to 66.7 MHz. Designed for 3.3-volt logic systems, it utilizes LVTTL-compatible I/O interfaces. The device is housed in a 32-pin TQFP package suitable for surface-mount applications.

FIFOs Memory Feature Summary

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

FIFOs Memory Applications

• Data buffering for graphics processing systems
• Interprocessor communication links
• Local area network interface buffering

FIFOs Memory Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status as some variants may differ. Check current production lifecycle status, as this part number may be subject to discontinuation notices. Ensure ESD handling protocols are followed during installation due to moisture sensitivity classification.

FIFOs Memory Selection Notes

Select this component when a 72Kbit synchronous FIFO with 9-bit width is required. The 20ns access speed suits moderate-speed data buffering tasks. Verify that the 3.3V operating voltage aligns with the target system's power supply rails. Consider the TQFP-32 package dimensions for PCB layout constraints compared to PLCC alternatives.

FIFOs Memory Part Context

This device belongs to the 72V251 family of synchronous FIFO memories. It serves as a 3.3V version within the broader 72V series, offering compatibility with low-voltage digital logic environments. The family is designed to replace older high-voltage FIFO solutions in modern embedded systems requiring reliable data flow control.
