72235L25J

Overview

The Renesas Electronics Corporation 72235L25J is a synchronous First-In-First-Out (FIFO) memory device belonging to the 72235LB25 series. It features an organization of 2K x 18 bits, providing a total storage capacity suitable for data buffering applications. The component operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a PLCC-68 package. This asynchronous/synchronous interface chip supports high-speed data transfer with a maximum clock frequency of 28.5 MHz and an access time of 25 ns.

Feature Summary

Synchronous FIFO architecture for reliable data buffering
Wide 18-bit data bus width for parallel processing
High-speed operation up to 28.5 MHz clock frequency
Fast 25 ns access time for low-latency data handling

Applications

Data buffering between asynchronous systems
Parallel data acquisition interfaces
Signal processing pipeline stages
Communication protocol conversion buffers

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for end-of-life notices or discontinuation announcements from Renesas Electronics prior to finalizing design-in decisions. Ensure PLCC-68 footprint compatibility with existing PCB layouts.

Selection Notes

Select this part when an 18-bit wide synchronous FIFO is required rather than standard 8-bit or 9-bit widths. Compare against the 72V05L25JGI if 3.3V operation is needed instead of 5V. Consider the 72235LB25 series variants for different pinout or speed grades. Verify that the PLCC-68 package is available for your manufacturing process.

Part Context

The 72235L25J is part of Renesas' broader portfolio of high-performance FIFO memories, specifically the 72235 series. It shares architectural similarities with other devices in the family but is distinguished by its 18-bit data width and synchronous control logic. This places it in a niche category for wide-data-path applications compared to the more common 8/9-bit asynchronous counterparts like the 72V05 series.
