72V261LA15PF

FIFOs Memory Overview

The 72V261LA15PF is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single power supply voltage ranging from 3V to 3.6V, with a maximum supply current of 55mA. The component is housed in a 64-TQFP surface-mount package measuring 14x14mm and is rated for commercial operating temperatures between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) functionality for immediate data availability upon read enable assertion.
• Includes programmable flags to indicate Almost-Empty and Almost-Full status conditions.
• Features retransmit capability allowing the same data word to be output multiple times without reloading.
• Provides independent read and write clocks to facilitate simultaneous operations across different domains.

FIFOs Memory Applications

• Data buffering in telecommunications systems
• Video signal processing pipelines
• Interprocessor communication interfaces

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and moisture sensitivity level handling procedures during assembly. Ensure design-in compatibility with existing system voltage levels and timing constraints before procurement.

FIFOs Memory Selection Notes

Select this component when a high-density synchronous FIFO with 16K depth and 9-bit width is required. Consider the 10ns access speed for applications needing 66.7MHz throughput. Evaluate the 64-TQFP package for surface-mount integration. Compare against other 72V series variants if different access speeds or organizational structures are needed.

FIFOs Memory Part Context

This part belongs to the 72V SuperSync FIFO family, designed for low-power 3.3V operation. It serves as a functional replacement for older 5V devices like the 72261 series while offering enhanced performance. The 72V261LA15PF specifically denotes the 10ns speed grade within the LA suffix variant, distinguishing it from slower or faster alternatives in the lineup.

FIFOs Memory Replacement Considerations

The IDT72V261LA15PF is listed as an alias for this component. Verify pinout and electrical specifications match exactly when substituting. Check for updated packaging options such as tape and reel if available.
