72V271LA15TF8

FIFOs Memory Overview

The 72V271LA15TF8 is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 288K bits, organized as 32K words by 9 bits. The device supports a maximum data rate of 66.7MHz with an access time of 10ns. It operates on a single power supply voltage ranging from 3V to 3.6V and draws a maximum supply current of 55mA. Designed for unidirectional data transfer, it is housed in a 64-pin TQFP package measuring 10x10mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) functionality for reduced latency
• Includes programmable Almost-Empty and Almost-Full status flags
• Enables retransmit operations with fixed low first word data latency
• Features auto power down capability to minimize standby power consumption

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Clock domain crossing interfaces
• Data acquisition system temporary storage

FIFOs Memory Procurement Notes

This specific part number is officially discontinued and no longer in production. Verification of availability should focus on the alternative packaging option, 72V271LA15TF, which is listed as a substitute. Buyers must confirm RoHS compliance status differences between the obsolete TF8 variant and the available TF variant, as regulatory specifications may vary. Ensure that any remaining stock matches the required pinout and electrical characteristics before procurement.

FIFOs Memory Selection Notes

Select this component when a 32K x 9 synchronous FIFO with 10ns access time is required within a 3.3V logic environment. The 72V271LA15TF8 is suitable for applications needing unidirectional data flow and FWFT support. Consider the 72V271LA15TF if industrial temperature ranges (-40°C to +85°C) are necessary, as the TF8 is limited to commercial grades. Verify package dimensions against PCB layout constraints for the 64-TQFP form factor.

FIFOs Memory Part Context

The 72V271LA15TF8 belongs to the IDT 72V SuperSync FIFO family, designed for high-performance memory buffering. This series is characterized by independent read and write clocks, allowing simultaneous operation. The device is functionally compatible with other members of the 72V2x1 series, facilitating design upgrades or replacements within existing architectures that utilize similar FIFO technologies.

FIFOs Memory Replacement Considerations

The 72V271LA15TF is identified as a public confirmed substitute part number. Note that the TF variant offers an extended industrial temperature range compared to the TF8's commercial rating.
