72221L15PFGI

Overview

The Renesas 72221L15PFGI is a synchronous First-In, First-Out (FIFO) memory device with a storage capacity of 1K x 9 bits. It operates at a maximum data rate of 66.7MHz and features a 10ns access time. The component supports single-clock or asynchronous dual-clock operation via separate read and write clocks. It is housed in a 32-pin TQFP package and is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports both single-clock and asynchronous dual-clock configurations for flexible system integration
• Provides programmable flags to monitor FIFO status conditions such as full and empty states
• Features output enable control to place the data bus in a high-impedance state

Applications

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

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm the 32-TQFP package and industrial temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for product discontinuance notifications or obsolescence notices from the manufacturer before finalizing supply chain plans.

Selection Notes

Select this component when a 1K x 9 depth is required for synchronous data buffering applications. Ensure the design accommodates the 32-pin TQFP footprint and operates within the specified -40°C to +85°C temperature range. Verify that the 66.7MHz speed requirement aligns with system clock constraints.
