72V85L15PA8

FIFOs Memory Overview

The 72V85L15PA8 is an asynchronous dual FIFO manufactured by Renesas Electronics. It features a storage capacity of 144K bits, organized as two independent 8K x 9 memory blocks. The device operates with a maximum data rate of 40 MHz and provides a typical access time of 15 ns. It supports unidirectional bus directionality and functions within a supply voltage range of 3 V to 3.6 V. The component is housed in a 56-TSSOP surface-mount package.

FIFOs Memory Feature Summary

• Dual independent first-in-first-out memory architecture
• Asynchronous clocking mechanism for flexible interface timing
• Unidirectional data bus configuration

FIFOs Memory Applications

• Data buffering between disparate clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for automated assembly processes. Review technical documentation for any process change notices affecting electrical characteristics or pin compatibility.

FIFOs Memory Selection Notes

Select this component when dual independent asynchronous FIFOs are required with 15 ns access speed. Ensure system design accommodates the 56-pin TSSOP footprint and 3.3 V logic levels. Consider the unidirectional bus constraint during schematic capture. Verify that the 8K x 9 organization matches the specific data width and depth requirements of the target application.

FIFOs Memory Part Context

This part belongs to the 72V85 series of asynchronous dual FIFOs from Renesas. It serves as a legacy alternative to newer synchronous devices. The series typically offers moderate density solutions for general-purpose buffering applications where precise timing synchronization is managed externally rather than internally.
