72265LA15PFI

Overview

The Renesas 72265LA15PFI is a synchronous FIFO memory IC with a capacity of 288K bits, organized as 16K words by 18 bits. It operates at a data rate of 66.7MHz with an access time of 10ns. The device supports unidirectional bus direction and features programmable flags. It functions within a voltage range of 4.5V to 5.5V and consumes a maximum supply current of 60mA. The component is housed in a 64-TQFP package measuring 14x14mm.

Feature Summary

• Synchronous operation with 66.7MHz data rate
• Programmable status flags support
• Unidirectional data bus architecture

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

This component is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability is restricted to existing stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific revision level and RoHS compliance status, as legacy inventory may vary. Direct procurement from the manufacturer is not possible; substitute part numbers should be evaluated for design compatibility.

Selection Notes

Designers requiring this specific 16K x 18 synchronous FIFO configuration must account for its discontinued status. Selection should prioritize verified replacement components that match the 64-TQFP footprint and 5V operating voltage. Ensure that any alternative device maintains compatible timing characteristics and flag logic to prevent interface redesigns. Validate pinout compatibility before finalizing the bill of materials.

Part Context

The 72265LA series belongs to Renesas' SuperSync family of high-performance FIFO memories. These devices are designed for applications requiring large buffer depths and fast access times. The LA variant typically denotes specific speed grades and voltage ranges within the broader product line, offering reliable data integrity for digital signal processing tasks.

Replacement Considerations

Official substitutes include the 72V265LA15TFI8 and 72V265LA15TFGI8. These newer variants offer similar 16K x 18 capacity but operate at 3.3V instead of 5V. Verify voltage level translation requirements and check for package differences when transitioning to these replacements.
