72261LA10TF8

Overview

The 72261LA10TF8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The component operates with a 3.3V supply voltage and supports a data rate of 100MHz with a 6.5ns access time. It utilizes a unidirectional bus architecture and includes programmable flags for status monitoring. The device is housed in a 64-pin TQFP package and is designed for surface mount installation.

Feature Summary

• Supports simultaneous independent read and write operations using separate clocks
• Features fixed low first word data latency for retransmit operations
• Includes programmable Almost-Empty and Almost-Full status flags
• Provides auto power down capability to minimize standby power consumption

Applications

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

Procurement Notes

Verify the specific suffix configuration against official Renesas documentation to ensure compatibility with required operating conditions. Confirm moisture sensitivity levels and handling requirements prior to assembly. Check for end-of-life notices or obsolescence announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a high-speed synchronous FIFO with 16K x 9 organization is required. Ensure the design supports 3.3V logic levels and requires unidirectional data transfer. Verify that the 64-pin TQFP package fits the available board space and thermal constraints.

Part Context

This part belongs to the 72V261 series of SuperSync FIFOs. It serves as a 3.3V version functionally compatible with the older 5V 722x5 family. The series is designed for applications requiring large data buffering capabilities with low latency characteristics.

Replacement Considerations

The 72V261LA10TFG8 is listed as an upgrade replacement option. Verify pinout and electrical specifications match before substitution.
