72V255LA10TFI8

FIFOs Memory Overview

The 72V255LA10TFI8 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 operates with a maximum data rate of 66.7MHz and an access time of 10ns. It functions on a single 3V to 3.6V power supply and draws a maximum supply current of 55mA. The device supports unidirectional bus direction and includes programmable flags for status indication. It is housed in a 64-TQFP package measuring 14x14mm and is rated for an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports retransmit operation with fixed, low first word data latency time
• Features independent read and write clocks permitting simultaneous reading and writing
• Includes programmable Almost-Empty and Almost-Full flags for flexible status signaling
• Provides auto power down functionality to minimize standby power consumption

FIFOs Memory Applications

• Networking applications requiring large data buffering
• Video processing systems needing high-speed data handling
• Telecommunications equipment utilizing SuperSync FIFO technology
• Data communications interfaces demanding low latency

FIFOs Memory Procurement Notes

Verify the specific suffix I8 against official documentation to confirm industrial temperature grading and lead-free compliance status. Confirm RoHS directive adherence as some variants may not meet current standards. Check for End-of-Life notifications or Product Change Notices that may affect long-term availability. Ensure the 64-TQFP package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 8K depth is required. It is suitable for designs needing 10ns access times at 66.7MHz clock speeds. Choose this part if the application requires independent read/write clocks and programmable flag outputs. Verify that the 0°C to 70°C commercial temperature range meets the environmental constraints of the target system.

FIFOs Memory Part Context

This part belongs to the 72V2x5 SuperSync FIFO family from Renesas. It serves as a 3.3V version functionally compatible with the older 5V 722x5 series. The family is designed for applications requiring efficient data buffering between asynchronous domains. The 72V255 variant specifically offers 18-bit width, distinguishing it from narrower or wider options in the lineup.

FIFOs Memory Replacement Considerations

The 72V265LA10TFI8 is a pin-compatible alternative within the same family offering 16K x 18 organization. Verify functional compatibility with the 5V 72265 if migrating from legacy designs. Ensure voltage levels and timing parameters align with existing system requirements when substituting.
