72235LB15PF8

Overview

The Renesas 72235LB15PF8 is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.7 MHz with a 10 ns access time. The component features unidirectional bus directionality and is housed in a 64-TQFP package measuring 14x14 mm. It includes programmable status flags and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with simultaneous read and write capabilities
• Programmable status flags for empty, half-full, and full conditions
• Expandable word depth and bit width architecture

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between asynchronous clock domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist. Confirm RoHS compliance status, as some variants differ. Check current lifecycle status due to potential discontinuation notices. Ensure packaging type matches system requirements. Validate pinout compatibility if replacing older versions.

Selection Notes

Select this component for applications requiring high-speed synchronous data buffering with 18-bit word widths. Consider the 64-TQFP package for surface-mount assembly constraints. Evaluate power consumption at 60 mA maximum against system budgets. Verify temperature range suitability for harsh environments.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, designed for high-performance data handling. It shares architectural similarities with other members like the 72235LB15PFI8 but differs in packaging and specific electrical characteristics. The series targets robust industrial and commercial applications requiring reliable first-in-first-out data management.

Replacement Considerations

IDT72235LB15PFGI8 is a verified substitute offering identical functionality in a tape-and-reel package.
