72V221L15PFGI8

FIFOs Memory Overview

The 72V221L15PFGI8 is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 20mA. The device is housed in a 32-lead Thin Quad Flat Package (TQFP) measuring 7mm x 7mm. It supports programmable flags for status monitoring and functions across an industrial temperature range of -40°C to 85°C.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with clocked read and write controls for reliable data buffering
• Supports both single-clock and asynchronous dual-clock operation modes
• Includes programmable full and empty flag outputs for system status monitoring
• Compatible with 3.3V logic interfaces for integration into standard digital systems

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix '8' against official Renesas documentation to confirm tape-and-reel packaging versus tray configuration, as datasheets may list variations. Confirm RoHS compliance status and moisture sensitivity level requirements during handling. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure the selected variant matches the required lead-free specifications for your assembly process.

FIFOs Memory Selection Notes

Select this component when a 1K x 9 depth is required for synchronous data buffering applications. The 10ns access time suits high-speed interprocessor communication needs. Verify that the 32-TQFP package fits the board layout constraints. Consider the 9-bit bus width compatibility with the target system interface. Ensure the operating temperature range meets the environmental conditions of the final application.

FIFOs Memory Part Context

This part belongs to the 72V221 series of synchronous FIFO memories from Renesas. It serves as a specialized memory solution for temporary data storage in digital signal processing and communication systems. The series is designed to handle data flow mismatches between components operating at different speeds or protocols.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72V221 family. Verify if older IDT-branded equivalents are available. Confirm functional parity regarding bus width and speed before substitution.
