72211L15PFG

Overview

The 72211L15PFG is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage capacity of 4.5K bits organized as 512 words by 9 bits. The component supports a maximum data rate of 40MHz with an access time of 15ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 35mA. The device utilizes a unidirectional bus architecture and is housed in a 32-TQFP package measuring 7x7mm. It is designed for surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports synchronous operation with independent read and write clock controls for flexible data buffering applications.
• Features programmable flags to indicate FIFO status conditions such as full, empty, or near-full states.
• Provides 9-bit wide input and output ports suitable for standard data word widths without additional parity logic.

Applications

• Data buffering in graphics processing systems
• Packet buffering in local area network interfaces
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'L15' confirms the 4.5V-5.5V operating voltage range and 15ns access time variant. Confirm the 'PFG' suffix corresponds to the 32-TQFP plastic package with industrial/commercial temperature ratings. Check for RoHS compliance status as older variants may differ. Ensure the source document matches the exact part number to avoid confusion with asynchronous or different speed grades.

Selection Notes

Select this component when a synchronous FIFO with 512x9 depth is required for moderate-speed data buffering. It is suitable for systems operating at 5V logic levels requiring up to 40MHz throughput. Consider the 32-pin TQFP package constraints for PCB layout. Verify that unidirectional data flow meets the system interface requirements compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7200 series of high-performance FIFO memories. The 72211 model specifically addresses the need for reliable data synchronization between components running at different clock speeds. It serves as a bridge in digital signal processing chains where temporary storage is necessary to prevent data loss during transfer bursts.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Renesas obsolescence notices or technical support for direct replacements if this component is discontinued.
