72211L10PFGI8

Overview

The 72211L10PFGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 512 x 9 bits, organized as 4.5K total bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 35mA. The device is housed in a 32-TQFP (7x7) surface-mount package.

Feature Summary

• Supports synchronous operation for reliable high-speed data buffering
• Provides programmable flags for status monitoring
• Features depth and width expandability for system integration

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition systems requiring precise timing control

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Validate electrical parameters against original design constraints prior to implementation.

Selection Notes

This component is suitable for applications requiring deterministic latency and high throughput. Consider the 4.5V to 5.5V operating range when designing power supplies. The 32-TQFP package requires appropriate PCB footprint design. Evaluate end-of-life implications for long-term production planning.
