72T3685L5BBI

FIFOs Memory Overview

The Renesas 72T3685L5BBI is a high-performance First-In-First-Out (FIFO) memory device supporting both asynchronous and synchronous operation modes. It provides a storage capacity of 576K bits, organized as 16K words by 36 bits. The component features unidirectional data bus directionality and supports data rates up to 83MHz in asynchronous mode and 200MHz in synchronous mode. Access times are specified at 10ns for asynchronous and 3.6ns for synchronous configurations. It operates within a supply voltage range of 2.375 V to 2.625 V with a maximum current consumption of 70mA. The device is housed in a 208-PBGA package measuring 17x17 mm and functions across an industrial temperature range of -40°C to 85°C.

FIFOs Memory Feature Summary

• Supports dual-mode operation for both asynchronous and synchronous clocking applications
• Includes programmable flags and relay capability for flexible system integration
• Features First Word Fall Through (FWFT) support for reduced latency access

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between components operating at different clock domains
• Data acquisition systems requiring precise timing control

FIFOs Memory Procurement Notes

Verify the specific revision level and manufacturing date code upon procurement, as component specifications may evolve through production updates. Confirm compliance with relevant environmental directives such as RoHS status, noting that older batches may not meet current standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference official datasheets for any recent product change notices or end-of-life announcements before finalizing design-in decisions.

FIFOs Memory Selection Notes

Select this component when designing systems requiring wide data paths with 36-bit word lengths and high throughput capabilities. Consider the 208-pin BGA package constraints for PCB layout and thermal management. Evaluate power requirements against the 70mA maximum supply current specification. Ensure the host system can accommodate the 2.375 V to 2.625 V supply voltage window. Verify that the required access time aligns with either the 10ns asynchronous or 3.6ns synchronous performance metrics.

FIFOs Memory Part Context

This part belongs to the Renesas 72T series of FIFO memories, designed for high-performance data buffering applications. The series offers various configurations differing in depth, width, and package types. The 72T3685L5BBI specifically addresses needs for wide-data, high-speed synchronization in complex digital systems. It represents a specialized solution within the broader memory and storage category, focusing on temporal data alignment rather than long-term storage.

FIFOs Memory Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Check for pin-compatible alternatives within the same 72T family that match the 16K x 36 configuration. Verify electrical compatibility regarding voltage ranges and access times before substitution.
