72221L10PFGI

Overview

The Renesas 72221L10PFGI is a synchronous First-In, First-Out (FIFO) memory device featuring a 1K x 9 organization and a 3.3V supply voltage. It supports unidirectional data transfer with a maximum clock frequency of 100 MHz and an access time of 10 ns. The component operates within a commercial temperature range of 0°C to 70°C and is housed in a 32-pin TQFP package.

Feature Summary

• Supports dual-clock operation for asynchronous read/write cycles or single-clock synchronization
• Provides programmable full/empty flags for precise buffer status monitoring
• Features output enable control to place the data bus in a high-impedance state

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and moisture sensitivity handling procedures before assembly. Review official product change notices for any manufacturing site transitions or labeling updates that may affect integration.

Selection Notes

Select this part for applications requiring reliable 1K x 9 depth buffering at 100 MHz speeds. Ensure system design accommodates the 3.3V logic levels and 32-pin TQFP footprint. Consider alternative components if industrial temperature ranges or lead-free compliance are mandatory requirements.

Part Context

This component belongs to the IDT SyncFIFO family, designed for high-speed data buffering. It serves as a 3.3V variant within the broader 72221 series, offering standardized interfaces for digital signal processing and memory management tasks in embedded systems.
