72255LA15PF

Overview

The Renesas Electronics Corporation 72255LA15PF is a synchronous FIFO memory integrated circuit featuring an 8K x 18 bit organization, providing 144K bits of total storage capacity. It operates with a maximum data rate of 66.7MHz and supports a 10ns access time. The device utilizes a unidirectional bus architecture and functions within a supply voltage range of 4.0V to 5.5V. It is housed in a 64-pin TQFP package with surface mount installation. The component supports programmable flags for status monitoring.

Feature Summary

• Synchronous first-in-first-out memory architecture
• Unidirectional data bus interface
• Programmable flag support for status indication

Applications

• High-speed data buffering in communication systems
• Data rate matching between asynchronous components
• Temporary storage in digital signal processing pipelines

Procurement Notes

Verify the specific suffix requirements for your application, as variants such as 72255LA15PFGI exist. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing design-in decisions. Ensure compatibility with 5V logic levels if using standard variants.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit width is required. Compare against bidirectional alternatives like the 72245 series if two-way data flow is needed. Consider the 72V255 series for lower voltage operation at 3.3V. Verify that the 64-TQFP package fits the board space constraints and thermal requirements of the target system.

Part Context

This part belongs to the Renesas 72255 SuperSync FIFO family. It shares architectural similarities with other members like the 72255LB15PF but differs in speed grade and specific feature sets. The family is designed for high-performance memory applications requiring reliable data synchronization without complex control logic.
