72V2111L10PFG8

FIFOs Memory Overview

The Renesas 72V2111L10PFG8 is a synchronous First-In, First-Out (FIFO) memory device featuring a 512K x 9-bit organization and a total storage capacity of 4.5 Mbit. It operates within a 3.15 V to 3.45 V supply voltage range and supports a maximum clock frequency of 100 MHz with a 10 ns access time. The component utilizes a unidirectional bus architecture and is housed in a 64-lead Thin Quad Flatpack (TQFP) package measuring 14x14 mm. Designed for surface-mount installation, it functions reliably across an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports dual-clock operation where read and write clocks run asynchronously, or single-clock operation where they are tied together.
• Includes programmable flags indicating full, empty, and half-full buffer states for efficient data management.
• Features fast write-first (FWFT) capability ensuring the most recently written data is immediately available upon reading.

FIFOs Memory Applications

• Data buffering in graphics processing systems
• Data handling in local area network interfaces
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm that the specific suffix matches the required package type and lead finish. Ensure compatibility with existing board layouts regarding the 64-TQFP footprint. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 512K x 9 synchronous FIFO is required for high-speed data buffering applications. It is suitable for designs needing 100 MHz performance with a 3.3V logic interface. Consider the 64-TQFP package constraints and the 0°C to 70°C industrial temperature range during system integration planning.

FIFOs Memory Part Context

This part belongs to the 72V2111 series of synchronous FIFOs manufactured by Renesas Electronics. The series provides various speed grades and organizational options to accommodate different bandwidth requirements. The 72V2111L10PFG8 specifically represents the 10 ns speed grade variant within this family, offering a balance between speed and power consumption for standard industrial applications.

FIFOs Memory Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Verify functional equivalence regarding speed grade, organization, and package dimensions before considering alternatives.
