72V255LA20PF

FIFOs Memory Overview

The 72V255LA20PF is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 144K bits, organized as 8K words by 18 bits. The component supports a maximum data rate of 50MHz with an access time of 12ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 55mA. The device is housed in a 64-TQFP package (14x14mm) and functions within an industrial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports unidirectional data flow with independent read and write clock domains for simultaneous operations.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full status signaling.
• Features auto power-down capability to minimize standby power consumption.
• Provides retransmit operation functionality with fixed first word data latency.

FIFOs Memory Applications

• Data buffering in telecommunications systems
• Video signal processing applications
• Networking equipment data management
• General data communications interfaces

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Validate pin compatibility with existing PCB layouts if replacing legacy components. Ensure supply chain stability given discontinued manufacturing status.

FIFOs Memory Selection Notes

Select this component for applications requiring 18-bit wide synchronous FIFO buffering at moderate speeds. Consider the 64-pin TQFP package constraints for board space limitations. Evaluate power consumption needs against the 55mA maximum draw. Compare performance metrics with newer SuperSync series alternatives if long-term availability is critical. Verify temperature range suitability for specific operational environments.

FIFOs Memory Part Context

This part belongs to the 72V255 family of synchronous FIFO memories from Renesas. It serves as a functional replacement for older 5V logic families while operating on 3.3V supplies. The device maintains pin compatibility with related SuperSync FIFO variants. It represents a transition component between legacy 5V designs and modern low-power architectures.
