72235LB10TF8

Overview

The Renesas 72235LB10TF8 is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates at a maximum data rate of 100MHz with a 6.5ns access time. The component supports unidirectional bus direction and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 60mA. The device is housed in a 64-TQFP (10x10) surface-mount package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Programmable flag support for customizable status indication
• Unidirectional data bus architecture for dedicated input or output paths

Applications

• Data buffering in high-speed digital systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix TF8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with 4.5V to 5.5V logic levels. Confirm moisture sensitivity level requirements for surface-mount assembly processes. Check for end-of-life notices or obsolescence announcements prior to procurement.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 2K depth is required. The 100MHz speed and 6.5ns latency suit high-throughput applications. Consider the 64-TQFP package for board space constraints. Verify that unidirectional flow meets system design needs compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB10TFG8, differing primarily in packaging and reel specifications. The series provides reliable data buffering solutions for various industrial and commercial electronic applications requiring synchronized memory management.

Replacement Considerations

The IDT72235LB10TF8 is listed as an alias for this component. Verify pinout and electrical characteristics match exactly before substitution. No other cross-model replacements are confirmed in the provided data.
