72235LB25PF8

Overview

The Renesas 72235LB25PF8 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 40MHz with a 15ns access time. The component supports unidirectional bus direction and accepts a supply voltage between 4.5V and 5.5V. It features programmable flags and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP package.

Feature Summary

• Synchronous operation for reliable data buffering
• Programmable status flags for flow control
• Unidirectional data transfer capability

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in communication protocols

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates conflicting information regarding the specific PF8 suffix variant. Confirm end-of-life status and lead-free availability through official Renesas channels before procurement planning.

Selection Notes

Select this component when a 36K-bit synchronous FIFO with 18-bit width is required. Ensure system timing aligns with the 15ns access specification and 40MHz operational limit. Verify power supply stability within the 4.5V to 5.5V range for proper functionality.

Part Context

This part belongs to the IDT 722x5LB series of synchronous FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in speed grade and package type. The series is designed for general-purpose memory buffering applications.

Replacement Considerations

IDT72235LB25PF8 is an alias for this component. Direct substitutes within the same speed grade and package should be sourced from Renesas or authorized distributors due to discontinuation notices.
