72225LB15TFI8

Overview

The Renesas 72225LB15TFI8 is a synchronous FIFO memory device belonging to the 7200 series. It features an 18Kbit storage capacity organized as 1K x 18 bits with unidirectional bus direction. The component supports data rates up to 66.7MHz and offers a 10ns access time. It operates on a single 4.5V to 5.5V power supply with a maximum current consumption of 60mA. The device is housed in a 64-TQFP surface-mount package and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation for reliable data buffering between asynchronous domains
• Programmable status flags for monitoring full and empty conditions
• High-speed data transfer capability supporting 66.7MHz clock frequencies

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in telecommunications equipment

Procurement Notes

Verify the exact suffix configuration, as 'TFI' typically denotes specific packaging or tape-and-reel variations compared to standard tray options. Confirm RoHS compliance status, as older variants may not meet current environmental standards. Check for active discontinuation notices from Renesas, as this part number may be subject to end-of-life restrictions requiring design changes or alternative sourcing strategies.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit word width is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 64-TQFP package dimensions for PCB layout constraints. Verify that the 10ns access time meets the timing requirements of the target application interface.

Part Context

This part belongs to the Renesas 72225 series of synchronous FIFOs, designed for high-performance data buffering applications. The series is known for its flexibility in depth and width configurations. Renesas Electronics Corporation, formerly NEC Electronics, manufactures this component line for industrial and commercial electronic systems requiring reliable memory management.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Generic substitutes may differ in pinout compatibility or electrical specifications. Validate any replacement against the original datasheet parameters before implementation.
