72V271LA15PFGI8

FIFOs Memory Overview

The 72V271LA15PFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 32K x 9 bits, totaling 288 Kbits. The component supports a data rate of 66.7 MHz with an access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum supply current of 55 mA. The device is housed in a 64-TQFP package measuring 14x14 mm and is rated for an industrial operating temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports unidirectional bus direction with programmable flags for empty, full, and half-full status indication.
• Features fixed, low first word data latency time and retransmit operation capabilities.
• Allows independent read and write clocks to permit simultaneous reading and writing operations.
• Includes auto power down functionality to minimize standby power consumption.

FIFOs Memory Applications

• Data buffering in graphics systems
• Local area network interfaces
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify the specific ordering suffix PFGI8 to confirm the tape and reel packaging configuration, as this affects handling procedures. Confirm RoHS3 compliance status through official documentation before integration. Check for any recent Product Change Notices regarding assembly sites or labeling changes that may impact qualification. Ensure the procurement channel provides valid traceability records for the component lot.

FIFOs Memory Selection Notes

Select this component when a 32K depth and 9-bit width are required for synchronous data buffering applications. The 10 ns access time suits high-speed interface requirements up to 66.7 MHz. Consider the 64-TQFP package constraints for PCB layout. Verify that the 3.3V supply rail matches the system design, as the device does not support 5V operation directly.

FIFOs Memory Part Context

This part belongs to the 72V271 series of SuperSync FIFO memories. It is functionally compatible with previous generations but optimized for 3.3V operation. The device eliminates the Frequency Select pin found in older variants, simplifying clock management between RCLK and WCLK inputs.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires checking functional compatibility with other 32K x 9 synchronous FIFO devices from the same manufacturer family.
