72271LA15TF8

Overview

The Renesas Electronics Corporation 72271LA15TF8 is a synchronous FIFO memory integrated circuit featuring a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The device supports unidirectional bus directionality and functions within a supply voltage range of 4.5V to 5.5V. It draws a maximum supply current of 75mA and is designed for surface mount installation in a 64-TQFP package measuring 14x14mm. The component supports programmable flags and full water full/empty flag types.

Feature Summary

• Supports synchronous operation with high-speed data transfer capabilities up to 66.7MHz.
• Includes programmable status flags for monitoring buffer occupancy levels.
• Features unidirectional data flow architecture for simplified interface design.
• Provides relay capability for signal buffering and timing adjustment.

Applications

• Data buffering between asynchronous system domains
• Interface bridging in high-speed digital communication systems
• Signal processing pipeline staging

Procurement Notes

Verify the exact part number suffix against official Renesas documentation, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status, as this specific revision may not meet current environmental standards. Check for active product change notices regarding pinout or electrical parameter updates before finalizing procurement plans.

Selection Notes

Select this component when a synchronous FIFO with 32K x 9 depth and 10ns access speed is required. Ensure the system operates within the 4.5V to 5.5V supply range. Verify that the 64-TQFP package dimensions fit the PCB layout constraints. Consider the 75mA current consumption for power budget calculations.

Part Context

This device belongs to the 7200 series of FIFO memories from Renesas Electronics. It shares architectural similarities with other members like the 72V271LA15TF8 but differs in operating voltage and package size. The 72271 variant specifically targets applications requiring standard 5V logic compatibility with moderate speed requirements.

Replacement Considerations

Public confirmed substitute: 72V271LA15TF8. Note that this alternative operates at a lower voltage (3V-3.6V) and uses a smaller 10x10mm package. Verify voltage level shifting and physical footprint compatibility before substitution.
