72211L25PFG

Overview

The 72211L25PFG is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. 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 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 35mA. The device is housed in a 32-TQFP package measuring 7x7 mm and is designed for surface mount installation. It includes programmable flags and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls
• Supports single-clock or dual-clock asynchronous operation modes
• Includes programmable status flags for full and empty conditions
• Provides 9-bit wide input and output data ports

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and environmental compliance. Confirm that the 'PFG' designation corresponds to the 32-TQFP lead-free variant. Check for any recent product discontinuance notifications or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 512x9 synchronous FIFO is required for 5V logic systems. Ensure the application demands a 40MHz maximum operating frequency and 15ns access time. Verify that the 32-pin TQFP footprint fits the PCB layout constraints. Confirm compatibility with 4.5V to 5.5V power supplies and check if programmable flags meet system monitoring requirements.

Part Context

This part belongs to the 72211 series of synchronous FIFOs from Renesas. It serves as the 5V version of the 72V211 family, which operates at 3.3V. The series is designed for high-speed data buffering applications requiring reliable synchronization between different clock domains or processors.

Replacement Considerations

The 72V211L25PFG is a 3.3V equivalent within the same functional family but requires different voltage levels. Direct pin-compatible replacements must be verified against current Renesas portfolios for availability and updated specifications.
