72265LA15PFGI8

Overview

The 72265LA15PFGI8 is a SuperSync FIFO memory device manufactured by Renesas Electronics. It features an organization of 16K x 18 bits, providing a total storage capacity of 288 Kbit. The component operates with a synchronous interface and supports a data rate of 66.7 MHz. It utilizes a 3.3V supply voltage and offers a read/write cycle time of 10 ns with an access time of 6.5 ns. The device is housed in a 64-pin TQFP package.

Feature Summary

• SuperSync architecture enables independent read and write clocks for simultaneous operations
• Fixed low first word data latency minimizes delay during retransmit operations
• Programmable Almost-Empty and Almost-Full flags allow flexible status monitoring
• Auto power down functionality reduces standby power consumption

Applications

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

Procurement Notes

Verify the specific suffix 'LA' against official Renesas documentation to confirm pin compatibility and functional equivalence with other 72V2x5 family members. Confirm that the 3.3V supply requirement aligns with system design constraints. Check for any product change notices regarding package or material updates before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring high-speed synchronous buffering with independent clock domains. Ensure the 3.3V logic level matches the host interface. Consider the 64-pin TQFP footprint for PCB layout. Verify that the 16K depth meets the buffer requirements for the specific application throughput.

Part Context

This part belongs to the Renesas SuperSync FIFO family, designed as a low-power alternative to older 5V devices. It maintains functional compatibility with the 722x5 series while operating at 3.3V. The removal of the Frequency Select pin simplifies clock management compared to previous generations.

Replacement Considerations

The IDT72265LA15PFGI8 is an alias for this component. Verify cross-compatibility with the 72V265LA15PFGI8 variant if available, ensuring identical pinout and electrical characteristics.
