72261LA15TF

Overview

The Renesas Electronics Corporation 72261LA15TF is a synchronous First-In, First-Out (FIFO) memory device. It features a data organization of 16K words by 9 bits, providing a total storage capacity of 144 kilobits. The component supports a maximum clock frequency of 66.7 MHz and offers an access time of 10 nanoseconds. It operates within a supply voltage range of 3.0 V to 3.6 V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 10 mm by 10 mm.

Feature Summary

• Synchronous operation with independent read and write clocks allows simultaneous data handling.
• Programmable status flags including Empty, Full, Half-Full, Almost-Empty, and Almost-Full for precise buffer management.
• Supports retransmit operations with fixed, low first-word data latency.
• Auto power-down capability minimizes standby power consumption.

Applications

• Data buffering in telecommunications systems
• Video signal processing applications
• Networking equipment data flow control
• Interprocessor communication interfaces

Procurement Notes

Verify the specific suffix 'TF' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records may vary. Check for End-of-Life notices or discontinuance notifications prior to procurement. Ensure design-in compatibility with existing system voltage levels and timing requirements.

Selection Notes

Select this component when a 16K x 9 synchronous FIFO is required with 10 ns access speed. Verify that the 3.3V operating voltage aligns with the target system architecture. Consider the 64-pin TQFP footprint for PCB layout constraints. Evaluate if the programmable flag outputs meet the specific interface logic requirements of the host processor.

Part Context

This part belongs to the 72261 series of SuperSync FIFOs designed for high-speed data buffering. It serves as a functional equivalent to older 5V devices but operates at lower voltage for reduced power dissipation. The series is widely used in applications requiring reliable data synchronization between asynchronous domains.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. No direct public substitute part numbers are confirmed in the provided source material.
