72211L15PFGI

Overview

The Renesas 72211L15PFGI is a synchronous First-In, First-Out (FIFO) memory device featuring a storage capacity of 4096 words by 9 bits. It operates with a maximum clock frequency of 66.7 MHz and an access time of 15 nanoseconds. The component supports unidirectional data transfer and functions within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Feature Summary

• Supports high-speed synchronous data buffering for interprocessor communication
• Provides flexible clocking options including single-clock or dual-clock asynchronous operation
• Features programmable full and empty flags for status monitoring

Applications

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

Procurement Notes

Verify the specific suffix PFGI against official datasheets to confirm package type and lead-free status. Check for Product Change Notices regarding obsolescence or pinout modifications. Ensure compatibility with existing board layouts for the 64-TQFP footprint before procurement.

Selection Notes

Select this component when a 4K x 9 synchronous FIFO is required for 5V logic systems. Compare against the 3.3V 72V211 series if lower voltage operation is needed. Verify that the 15ns access time meets system timing requirements compared to faster 10ns alternatives.

Part Context

This part belongs to the 72211 family of synchronous FIFOs from Renesas. It serves as the 5V version of the 72V211 series. The family is designed for applications requiring reliable data buffering between components operating at different speeds or domains.

Replacement Considerations

The 72V211L15PFGI is a compatible 3.3V alternative within the same family. Verify voltage level translation requirements when substituting. Other 72211 variants may offer different package styles or access times.
