72211L15PFG8

Overview

The 72211L15PFG8 is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features an organization of 512 words by 9 bits, providing a total storage capacity of 4.5 Kbits. The component operates with a maximum clock frequency of 100 MHz and supports a data rate of 66.7 MHz. Access time is specified at 6.5 ns. It functions as a unidirectional buffer suitable for graphics, local area networks, and interprocessor communication applications.

Feature Summary

• Synchronous FIFO architecture with clocked read and write controls
• High-speed operation supporting up to 100 MHz clock frequencies
• Unidirectional bus interface designed for data buffering tasks

Applications

• Graphics data buffering
• Local area network interfaces
• Interprocessor communication systems

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and lead-free status. Confirm availability status as this part may be discontinued or subject to limited supply constraints. Ensure compliance with RoHS directives if required for your application. Check for moisture sensitivity levels prior to soldering processes.

Selection Notes

Select this component when a synchronous FIFO with 512x9 organization is required. Consider the 6.5 ns access time and 100 MHz capability for high-speed buffering needs. Compare against the standard 72211 series for voltage compatibility and pinout requirements. Verify that the TQFP-32 package fits the board layout constraints.

Part Context

This device belongs to the 72V211/72211 family of synchronous FIFOs. It serves as a specialized memory solution for temporary data storage in digital systems. The L15 designation typically indicates specific electrical characteristics within the broader product line. It complements other memory solutions like dual-port RAMs for complex system architectures.

Replacement Considerations

Check for direct substitutes such as the IDT72211L15PFG8 or compatible variants from other manufacturers offering identical 512x9 synchronous FIFO specifications. Ensure pin compatibility and timing parameters match before substitution.
