72225LB20TF

Overview

The Renesas Electronics Corporation 72225LB20TF is a synchronous FIFO memory device belonging to the 7200 series. It features an 18K storage capacity organized as 1K x 18 bits with unidirectional bus directionality. The component supports data rates up to 66.7MHz and achieves a 10ns access time. It operates 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 (10x10) surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Synchronous operation with programmable flags for status monitoring
• Expandable architecture supporting depth and width expansion
• Industrial-grade reliability with wide operating temperature range

Applications

• Data buffering in high-speed digital systems
• Interprocessor communication interfaces
• Local Area Network (LAN) controller applications

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as historical records indicate non-compliance for this specific part number. Validate package dimensions against design requirements prior to integration. Check for end-of-life notices or discontinuance notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 1K x 18 bit synchronous FIFO is required with 10ns access speed. Ensure system power supplies remain within the 4.5V to 5.5V range. Verify that the 64-TQFP footprint matches the PCB layout. Consider thermal management capabilities given the industrial temperature rating and unidirectional data flow requirements.

Part Context

This device is part of the Renesas 7200 series of synchronous FIFOs, designed for efficient data buffering. It shares architectural similarities with other members like the 72225LB15TFI but differs in speed grade and packaging specifics. The series is known for providing reliable first-in-first-out memory solutions for complex digital signal processing and communication tasks.
