72271LA15TFI8

Overview

The 72271LA15TFI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation, belonging to the 72V271 series. It provides a storage capacity of 288K bits organized as 32K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single power supply voltage ranging from 3V to 3.6V, with a maximum supply current of 55mA. The device is housed in a 64-pin TQFP package measuring 10x10mm and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports retransmit operation with fixed, low first word data latency time
• Features programmable almost-empty and almost-full flags for status signaling
• Allows independent read and write clocks to permit simultaneous operations
• Capable of easy expansion in both depth and width

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in telecommunications equipment
• Memory management in industrial control applications

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the 72V271 family regarding temperature range and packaging. Confirm RoHS compliance status, as some variants are non-compliant while others meet REACH standards. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the selected package matches the PCB footprint requirements precisely.

Selection Notes

Select this component when a synchronous FIFO with 32K x 9 organization and 10ns access time is required. Consider the 72V271 series if independent read/write clocks and retransmit capabilities are necessary for system timing. Evaluate the 3V to 3.6V supply requirement against available power rails. Compare pin compatibility with other 72V271 variants if design flexibility is needed.

Part Context

This part belongs to the Renesas 72V271 SuperSync FIFO family, which features clocked read and write controls. The series eliminates variable clock cycle counting delays found in previous generations, providing fixed latency. Devices in this family are available in 64-pin TQFP packages and support industrial temperature ranges in specific variants.

Replacement Considerations

The IDT72271LA15TFGI8 is listed as an alias for this component. Verify pinout and electrical specifications against the official datasheet before substitution.
