72V221L15PFG

FIFOs Memory Overview

The Renesas 72V221L15PFG 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 operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 66.7 MHz with a 10 ns access time. The component utilizes a 32-pin TQFP package measuring 7x7 mm and is rated for an industrial operating temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports dual-clock operation where read and write clocks function independently or single-clock mode when tied together.
• Features a zero fall-through time architecture ensuring immediate data availability upon valid read commands.
• Includes programmable status flags allowing users to configure Almost-Empty and Almost-Full thresholds at any depth.

FIFOs Memory Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

FIFOs Memory Procurement Notes

Verify the specific suffix PFG against official datasheets to confirm the TQFP-32 package variant. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check for end-of-life notifications or production change notices that may affect long-term availability and sourcing strategies.

FIFOs Memory Selection Notes

Select this component for applications requiring 9-bit wide data paths and asynchronous clock domain crossing. Ensure the system design accommodates the 3.3V logic levels and 10 ns timing constraints. Verify that the 32-pin TQFP footprint fits the PCB layout and thermal management requirements for the specified industrial temperature range.

FIFOs Memory Part Context

This part belongs to the 72V series of synchronous FIFOs from Renesas Electronics. It serves as the 3.3V version of the legacy 72221 device, maintaining compatibility while offering lower power consumption. The series is designed for high-speed data buffering in digital signal processing and networking equipment.

FIFOs Memory Replacement Considerations

The IDT72V221L15PFGI is listed as an alias for this component. Verify pinout and electrical specifications match exactly before substitution. No other cross-model replacements are confirmed in public documentation.
