72V255LA15PFGI8

FIFOs Memory Overview

The 72V255LA15PFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features an organization of 8K x 18 bits, providing a total storage capacity of 144 kbit. The component supports bidirectional data transfer and operates with a maximum clock frequency of 66.7 MHz. Electrical specifications include a minimum access time of 10 ns and a supply voltage range from 3 V to 3.6 V. The maximum power consumption is 55 mA. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 64-TQFP package.

FIFOs Memory Feature Summary

• Features programmable flags including Almost-Empty and Almost-Full indicators
• Enables retransmit operations with fixed first word data latency
• Provides independent read and write clocks for simultaneous data handling

FIFOs Memory Applications

• Data buffering in telecommunications systems
• Video signal processing applications
• Networking equipment data management
• Interprocessor communication interfaces

FIFOs Memory Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is restricted to existing stock or surplus channels only. Verify RoHS compliance details carefully as legacy parts may not meet current environmental standards. Confirm package integrity and moisture sensitivity levels before procurement. Ensure design-in compatibility with replacement strategies due to permanent discontinuation.

FIFOs Memory Selection Notes

Select this part for applications requiring high-speed synchronous buffering with bidirectional data flow capabilities. The 10 ns access time suits high-frequency data processing needs. Consider the 64-TQFP package constraints for PCB layout. Evaluate the 3 V to 3.6 V supply requirement against system power rails. Note that the bidirectional feature distinguishes it from unidirectional family members like the 72V255LA15PFI.

FIFOs Memory Part Context

Part of the 72V SuperSync FIFO family designed for low-power 3.3V operation. Functionally compatible with the older 5V 722x5 series but optimized for modern voltage levels. The LA suffix typically denotes specific speed grades or pin-compatible variations within the broader 72V product line. This specific variant offers expanded depth compared to smaller capacity counterparts in the same series.

FIFOs Memory Replacement Considerations

Official substitutes are unavailable due to discontinuation. Potential cross-reference candidates include other 8K x 18 synchronous FIFOs from Renesas or IDT, such as the 72V255LA15PFI, though functional differences like unidirectional buses must be verified. Check datasheets for pinout compatibility and electrical parameter alignment.
