72271L15PF

Overview

The Renesas Electronics Corporation 72271L15PF is a synchronous FIFO memory device with a storage capacity of 288K organized as 32K x 9 bits. It operates at a data rate of 66.7MHz with an access time of 10ns. The component supports unidirectional bus direction and features programmable flags and FWFT support. It functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum current of 75mA. The device is housed in a 64-TQFP (14x14) package and operates between 0°C and 70°C.

Feature Summary

• Synchronous first-in-first-out memory architecture for data buffering
• Supports full water full threshold flag functionality
• Includes programmable status flags for system monitoring

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic domains
• Temporary storage in communication protocols

Procurement Notes

Verify the obsolete status and RoHS non-compliance before integration. Confirm availability through authorized channels as standard distribution may be limited. Ensure design reviews account for the specific 64-TQFP footprint and moisture sensitivity level requirements during handling and assembly processes.

Selection Notes

Select this component for applications requiring 32K x 9 bit synchronous buffering at 66.7MHz. Consider the 4.5V to 5.5V operating range and 64-pin TQFP package constraints. Evaluate power consumption limits and thermal dissipation capabilities relative to the 75mA maximum supply current specification.
