72211L25JG8

Overview

The 72211L25JG8 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 unidirectional data transfer with a maximum operating frequency of 40 MHz and an access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 35 mA. Designed for surface-mount installation, it is housed in a 32-lead Thin Quad Flat Package (TQFP) measuring 7 mm by 7 mm.

Feature Summary

• Synchronous FIFO architecture with independent read and write clock controls
• Programmable status flags indicating full, empty, and half-full conditions
• Unidirectional data bus interface optimized for buffering applications

Applications

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

Procurement Notes

Verify the specific suffix JG8 against official Renesas documentation to confirm package dimensions and lead finish specifications. Ensure compatibility with 4.5 V to 5.5 V logic levels before integration. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Validate moisture sensitivity level requirements for your assembly process.

Selection Notes

Select this component when a 512x9 synchronous FIFO is required for 5V logic systems. Compare against the 72V211 series if 3.3V operation is necessary instead. Consider the 25 ns access time against system timing constraints. Verify that the TQFP-32 package fits the available PCB footprint and thermal requirements.

Part Context

This part belongs to the Renesas 72211 family of synchronous FIFOs. These devices are designed for high-speed data buffering between asynchronous or synchronous domains. The 72211 series provides reliable temporary storage for digital signals in embedded and industrial applications requiring precise data flow control.

Replacement Considerations

Check for direct pin-compatible replacements within the 72211 series. Verify if the 3.3V variant 72V211 meets voltage requirements. Consult Renesas for end-of-life notices or recommended upgrades.
