72235LB15TFGI

Overview

The Renesas 72235LB15TFGI is a synchronous FIFO memory device with a capacity of 36K bits, organized as 2K words by 18 bits. It operates at a maximum data rate of 66.7MHz with an access time of 10ns. The component supports unidirectional bus architecture and functions within a supply voltage range of 4.5V to 5.5V. It features programmable flags and is housed in a 64-TQFP (10x10) surface-mount package.

Feature Summary

• Synchronous operation supporting high-speed data buffering
• Programmable status flags for flow control management
• Unidirectional data transfer architecture

Applications

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

Procurement Notes

Verify current availability status as the component may be subject to discontinuation or last-time-buy notices. Confirm RoHS compliance requirements against specific project standards, as older variants may not meet current environmental regulations. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required for unidirectional data paths. The 10ns access time suits applications needing low-latency buffering at frequencies up to 66.7MHz. Consider the 64-TQFP package constraints for PCB layout and thermal management during design integration.

Part Context

This part belongs to the IDT 72235 series of synchronous FIFOs, designed for high-performance memory buffering. The series typically offers various speed grades and package options to accommodate different system timing and physical footprint requirements within industrial and commercial electronic designs.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 72235 family, such as the 72235LB15PFI, ensuring identical electrical characteristics and package dimensions before substitution.
