72V255LA15PFGI

FIFOs Memory Overview

The Renesas 72V255LA15PFGI is a synchronous FIFO memory device with an organization of 8K x 18 bits, providing a total storage capacity of 144 Kbits. It operates on a single 3 V to 3.6 V power supply and supports data rates up to 66.7 MHz with a 10 ns access time. The component features unidirectional bus orientation and is housed in a 64-TQFP package.

FIFOs Memory Feature Summary

• Supports retransmit operations with fixed, low first word data latency time
• Features programmable Almost-Empty and Almost-Full flags for status signaling
• Allows independent read and write clocks for simultaneous operation
• Includes auto power down functionality to minimize standby power consumption

FIFOs Memory Applications

• Networking data buffering
• Video signal processing
• Telecommunications systems
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix 'GI' against official Renesas documentation to confirm lead-free compliance and RoHS status, as generic listings may vary. Confirm current lifecycle status, as this part number appears discontinued in some distributor records. Ensure the 64-TQFP package dimensions match your PCB footprint requirements before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a 144 Kbit synchronous buffer is required for high-speed data transfer applications. It serves as a 3.3V compatible alternative to older 5V families. Consider the 10 ns access speed and 66.7 MHz frequency limits for timing constraints. Verify if the 64-pin TQFP package is suitable for your assembly process and thermal management needs.

FIFOs Memory Part Context

This device belongs to the SuperSync FIFO family, designed for low power consumption and high performance. It is functionally compatible with the 5V 722x5 family but optimized for 3.3V operation. The removal of the Frequency Select pin simplifies clocking configurations compared to previous generations.
