72225LB20PF

Overview

The Renesas Electronics Corporation 72225LB20PF is a synchronous FIFO memory device with a capacity of 1K x 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 66.7 MHz. The component features a 10 ns access time and is housed in a 64-TQFP (14x14) surface-mount package. It functions as a uni-directional buffer with programmable flags and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation for reliable data buffering
• Uni-directional data transfer capability
• Programmable status flags for flow control

Applications

• High-speed data buffering in digital systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify RoHS compliance status and moisture sensitivity levels before procurement. Confirm end-of-life notices and potential replacement options through official Renesas channels.

Selection Notes

Select this part for applications requiring a compact 1K x 18-bit synchronous FIFO solution. Ensure the design accommodates the 64-TQFP package dimensions and 4.5 V to 5.5 V power requirements. Consider the 66.7 MHz maximum data rate and 10 ns access time against system timing constraints. Verify thermal management for the specified operating temperature range.

Part Context

The 72225LB20PF belongs to the Renesas 7200 series of high-performance FIFOs. This series is designed for ultra-fast, compact data handling in embedded and industrial applications. The component integrates SRAM technology with synchronous control logic to provide efficient memory buffering without external clock synchronization complexity.

Replacement Considerations

Official substitutes include the IDT72225LB20PF variant. Cross-reference pinouts and electrical specifications carefully when considering alternative sources due to the component's discontinued status.
