72261LA20PF8

Overview

The 72261LA20PF8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It provides a storage capacity of 144K bits, organized as 16K words by 9 bits. The component supports data rates up to 50MHz with an access time of 12ns. It operates within a supply voltage range of 3V to 3.6V or 4.5V to 5.5V depending on the specific variant documentation, and functions within a commercial temperature range of 0°C to 70°C. The device is housed in a 64-TQFP package.

Feature Summary

• Synchronous operation with clocked read and write controls for reliable data transfer
• Supports programmable flags to indicate full and empty buffer states
• Enables depth and width expansion for flexible system integration
• Includes first-word-fall-through capability for low-latency data access

Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic blocks
• Data acquisition systems requiring temporary storage
• Network processing units managing packet flows

Procurement Notes

Verify RoHS compliance status carefully as sources indicate conflicting information regarding REACH and RoHS3 adherence for this specific suffix. Confirm the exact operating voltage range required for your design, as documentation varies between 3V and 5V specifications. Ensure the 64-TQFP package dimensions match your PCB footprint requirements before ordering.

Selection Notes

Select this component when synchronous FIFO functionality with programmable status flags is required. Consider the 12ns access time and 50MHz data rate for high-speed applications. Verify compatibility with your system's voltage levels, noting discrepancies in available datasheets regarding 3V versus 5V operation. Check for obsolescence status as some sources list this part as discontinued.

Part Context

This part belongs to the 72V series of SuperSync FIFO memories from Renesas. It shares architectural similarities with other devices in the family but offers specific 16K x 9 organization. The LA20 suffix typically denotes speed grade and package type variations within the broader product line.

Replacement Considerations

The 72261LA20PFG8 is listed as a potential alternative in some databases. Verify pinout and electrical specifications against the original datasheet before substitution.
