72V221L15JI8

FIFOs Memory Overview

The Renesas 72V221L15JI8 is a synchronous First-In, First-Out (FIFO) memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It supports unidirectional data transfer at a maximum data rate of 66.7MHz with an access time of 10ns. The component operates on a single supply voltage ranging from 3V to 3.6V and draws a maximum supply current of 20mA. It is housed in a 32-PLCC package measuring 14x11.46mm and is designed for surface mount installation within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with independent read and write clock controls
• Configurable programmable flags for status monitoring
• Supports both single-clock and dual asynchronous clock operations

FIFOs Memory Applications

• Graphics data buffering
• Local area network interface buffering
• Interprocessor communication link management

FIFOs Memory Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm the exact package variant and temperature rating. Confirm RoHS compliance status and check for End-of-Life notices or Product Change Notifications prior to procurement. Ensure the ordering part number matches the required pinout and electrical specifications exactly.

FIFOs Memory Selection Notes

Select this component when a 9-bit wide synchronous FIFO buffer is required for data rate matching between asynchronous systems. The 1K depth provides adequate buffering for moderate throughput applications. Verify that the 3.3V logic levels are compatible with the system's I/O standards and that the PLCC package fits the available PCB footprint constraints.

FIFOs Memory Part Context

This device belongs to the Renesas 72V series of high-performance synchronous FIFO memories. It serves as a 3.3V version of earlier devices, offering improved performance for modern digital systems. The 72V221 family is widely used in embedded systems requiring reliable data buffering between components operating at different speeds or clock domains.

FIFOs Memory Replacement Considerations

Check for direct cross-reference part numbers such as IDT72V221L15JI8. Verify pin compatibility and electrical parameters before substituting. Consult Renesas for any updated equivalents if the original part is discontinued.
