72235LB10PFI

Overview

The Renesas Electronics Corporation 72235LB10PFI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP package measuring 14x14mm.

Feature Summary

• Synchronous first-in-first-out memory architecture for buffering data streams
• Supports programmable status flags to monitor buffer levels
• Capable of expanding both word depth and bit width

Applications

• Multiprocessing systems requiring data synchronization
• Rate matching between asynchronous data sources
• Buffering applications in high-speed digital circuits

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Validate pin compatibility with existing PCB footprints. Review datasheet revisions for any functional updates or warnings.

Selection Notes

Select this component when a 2K x 18 synchronous FIFO is required. Ensure the design accommodates the 64-TQFP package dimensions. Verify that the 10ns access time meets system timing constraints. Confirm power supply stability within the 4.5V to 5.5V range. Consider lead availability given the discontinued status of the product line.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories. It shares architectural similarities with other members like the 72235LB15PFI but differs in speed and packaging. The series is designed for high-performance buffering in complex digital systems. Renesas continues to support legacy components for existing designs.
