72235LB15PFGI

Overview

The Renesas 72235LB15PFGI is a synchronous FIFO memory integrated circuit featuring a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The device supports unidirectional bus direction and programmable status flags. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. The component is housed in a 64-TQFP package (14x14mm) and is rated for an industrial operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities up to 66.7MHz
• Expandable architecture allowing depth and width configuration adjustments
• Integrated programmable status flags for precise buffer management
• Industrial-grade thermal stability suitable for demanding environments

Applications

• Multiprocessing systems requiring efficient data buffering
• Rate matching between asynchronous data streams
• High-speed digital signal processing interfaces
• Communication protocol conversion buffers

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm package type and RoHS compliance status. Confirm availability as this part may be subject to discontinuation notices. Ensure design-in compatibility with existing system voltage levels and timing requirements before procurement.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 2K depth is required. Compare against the 72231L series if a 9-bit width is sufficient, or the 72V205L series for lower voltage applications. Verify that the 64-TQFP package fits the PCB layout constraints and that the 10ns access time meets the system clock speed requirements.

Part Context

This part belongs to the Renesas 7200 series of high-performance FIFO memories. It is functionally related to other members like the 72235LB15PFI, differing primarily in packaging and potentially environmental ratings. The series is designed for robust data handling in complex electronic systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the 72235LB family. Verify if the 72235LB15PFI serves as a functional alternative, noting differences in packaging or environmental specifications. Consult Renesas PCN documents for any obsolescence information.
