72211L10PFGI

Overview

The Renesas Electronics Corporation 72211L10PFGI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 35mA. The device is housed in a 32-pin TQFP package (7x7mm) and is designed for surface mount installation. It includes programmable flags and functions within a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous first-in, first-out memory architecture supporting clocked read and write controls
• Configurable depth and width expansion capabilities for flexible system integration
• Programmable status flags for monitoring full and empty buffer conditions
• Single-supply operation compatible with standard 5V logic interfaces

Applications

• Data buffering in graphics processing systems
• Interprocessor communication links
• Local area network interface buffering

Procurement Notes

Verify the specific suffix 'PFGI' against official Renesas documentation to confirm pinout compatibility and lead-free status. Confirm that the industrial temperature grade variant is not required if the application exceeds the commercial range. Check for obsolescence notices or product change notifications regarding assembly sites or marking changes before finalizing procurement plans.

Selection Notes

Select this component when a 512x9 synchronous FIFO with 100MHz performance is required in a 32-pin TQFP package. Ensure the system design accommodates the 4.5V to 5.5V supply voltage range. Consider the 35mA maximum supply current for power budget calculations. Verify that the unidirectional data flow meets the system's signal direction requirements without needing bidirectional buffers.

Part Context

This part belongs to the Renesas 7200 series of SyncFIFO memories, which are widely used for high-speed data buffering applications. The series offers various densities and speeds, with the 72211 representing a mid-range density option. These devices are designed to handle data rate mismatches between asynchronous components, providing reliable temporary storage during data transfers.

Replacement Considerations

Check for direct replacements within the 722xx series with identical pinouts and electrical characteristics. Verify availability of alternative packages such as PLCC if TQFP sourcing is limited. Ensure any substitute maintains the same 5V supply requirement and 100MHz speed class.
