72V255LA15TFI8

FIFOs Memory Overview

The 72V255LA15TFI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 8K words by 18 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-TQFP package measuring 14x14mm and is rated for an industrial operating temperature range of -40°C to +85°C.

FIFOs Memory Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Procurement must rely exclusively on verified surplus or secondary market channels. Verify part authenticity against official Renesas documentation due to potential obsolescence risks. Confirm that replacement sources provide valid traceability and quality assurance records before acquisition.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 8K depth is required for 3.3V logic systems. Ensure compatibility with the 64-TQFP surface mount package constraints. Verify that the 66.7MHz clock speed meets system timing requirements. Consider functional equivalents within the 72V2xx family if pin-out compatibility is critical for existing board layouts.

FIFOs Memory Part Context

The 72V255LA15TFI8 belongs to the Renesas 72V SuperSync FIFO family, designed for high-performance data buffering. It serves as the 3.3V version of the legacy 72255 series, offering improved power efficiency while maintaining functional compatibility. The device utilizes independent read and write clocks to allow simultaneous operations, making it suitable for asynchronous data rate conversion tasks in embedded systems.

FIFOs Memory Replacement Considerations

Verify cross-compatibility with other members of the 72V2xx LA series for similar depth and width configurations. Check for updated RoHS compliance status in alternative components if environmental regulations apply. Ensure substitute devices support the same 64-TQFP footprint and electrical specifications.
