72261LA10TF

Overview

The 72261LA10TF is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage organization of 16K x 9 bits, providing a total capacity of 144 kilobits. The component operates with a core voltage range of 3V to 3.6V and supports data rates up to 100MHz. The access time is specified at 6.5ns. It utilizes a 64-pin TQFP package with dimensions of 10x10mm and a 0.5mm pitch. The device functions as a unidirectional buffer with independent read and write clocks.

Feature Summary

• Supports simultaneous independent read and write operations using separate clock domains
• Features fixed low first-word data latency for efficient buffering applications
• Includes programmable status flags indicating empty, full, half-full, almost-empty, and almost-full states
• Provides auto power-down capability to minimize standby power consumption

Applications

• Data buffering in telecommunications systems
• Video signal processing and transmission
• Networking equipment interface buffering
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'TF' against current manufacturer documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as older revisions may differ from current standards. Check for end-of-life notices or obsolescence announcements prior to final design commitment. Ensure supply chain availability aligns with project timelines given potential discontinuation risks associated with legacy part numbers.

Selection Notes

Select this component when a 16K x 9 synchronous FIFO with 6.5ns access time is required. Ensure the system design accommodates the 3V to 3.6V operating voltage range. Verify that the 64-pin TQFP footprint matches the PCB layout constraints. Consider the unidirectional bus architecture suitability for the specific data flow requirements of the application.

Part Context

This part belongs to the 72V261 series of SuperSync FIFOs. It is functionally compatible with the older 5V 72265 family but operates at lower voltage levels. The series is designed for high-speed data buffering in networking and telecommunications environments. It shares pin compatibility with other members of the 72V2x5 family for design flexibility.

Replacement Considerations

The 72V261LA10TFG8 is listed as an upgrade alternative. Verify pinout and electrical parameter equivalence before substitution. Ensure the replacement package variant meets mechanical and thermal requirements.
