72235LB25PF

Overview

The Renesas 72235LB25PF is a synchronous FIFO memory device with a 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 data transfer and includes programmable flags for status monitoring. It functions 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 and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides synchronous first-in-first-out buffering for high-speed data flow management
• Features programmable full and empty flags for precise buffer status indication
• Supports unidirectional data transfer architecture for dedicated input/output paths

Applications

• High-speed digital signal processing data buffering
• Interface bridging between asynchronous system components
• Data acquisition systems requiring temporary storage

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active production status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 2K x 18 word synchronous FIFO is required for unidirectional data handling. Ensure the design accommodates the 4.5V to 5.5V supply voltage requirement. Verify that the 64-TQFP package dimensions fit the target PCB layout constraints.
