72225LB25PFI

Overview

The Renesas 72225LB25PFI is a synchronous FIFO memory device with a storage capacity of 18K bits, organized as 1K words by 18 bits. It operates at a maximum data rate of 40MHz with a 15ns access time. The component supports unidirectional bus direction and programmable flags. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. The device is housed in a 64-TQFP package (14x14mm) and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with single-clock domain control
• Programmable status flags for full and empty conditions
• Wide 18-bit data bus width for high-throughput applications

Applications

• Buffering data streams between asynchronous clock domains
• High-speed interface matching in digital signal processing systems
• Temporary storage in communication protocol bridges

Procurement Notes

Verify the exact suffix PFI to confirm the 64-TQFP package and industrial temperature grade. Confirm RoHS compliance status as some sources indicate non-compliance. Check for End-of-Life notices or obsolescence warnings from Renesas before finalizing procurement plans due to potential availability constraints.

Selection Notes

Select this part when 18-bit wide synchronous buffering is required. Ensure the system voltage aligns with the 4.5V to 5.5V range. Consider the 64-TQFP footprint for PCB layout. Compare against other 72225 variants if different package types like PLCC are needed or if commercial temperature grades suffice instead of the industrial range specified here.

Part Context

This component belongs to the Renesas 7200 series of high-performance FIFO memories. It shares architectural similarities with other members like the 72235LB25PFI but differs in depth. The 'LB' designation typically indicates low-power CMOS technology. It is designed for applications requiring reliable, fast data synchronization without complex controller logic.

Replacement Considerations

Direct pin-compatible substitutes may include other 72225 series parts with different packages such as 72225LB25J8 (PLCC-68) or 72225LB25TF (TQFP-64). Verify electrical specifications and temperature ranges match before substitution.
