72V805L10PF

FIFOs Memory Overview

The 72V805L10PF is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 9K organized as 256 words by 18 bits with dual-port capability (256 x 18 x 2). The component supports bidirectional data bus operation and achieves a maximum data rate of 100MHz with a typical access time of 6.5ns. It operates within a supply voltage range of 3 V to 3.6 V, drawing a maximum supply current of 60mA. The device is housed in a 128-TQFP package measuring 14x20 mm and is designed for surface mount installation. It includes programmable flags and First-Word-Fall-Through (FWFT) support, functioning reliably within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports bidirectional data transfer between two independent clock domains
• Includes programmable status flags for full, empty, and threshold conditions
• Enables First-Word-Fall-Through (FWFT) functionality for immediate data availability

FIFOs Memory Applications

• Buffering data streams in high-speed digital signal processing systems
• Clock domain crossing interfaces in telecommunications equipment
• Data buffering in video processing and display controller applications

FIFOs Memory Procurement Notes

Verify the specific suffix 'PF' against the official Renesas datasheet to confirm the exact package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to integration. Check for any Product Change Notices (PCNs) regarding assembly sites or material updates. Ensure the design accommodates the specified 128-TQFP footprint and thermal requirements for the commercial temperature range.

FIFOs Memory Selection Notes

Select this component when bidirectional data flow is required between asynchronous clock domains. The 18-bit word width suits applications needing wider data paths than standard 8-bit or 16-bit FIFOs. Verify that the 100MHz speed meets system timing constraints and that the 3V to 3.6V supply aligns with the target platform's voltage rails. Consider the 128-pin package size for PCB layout feasibility.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of synchronous FIFOs, which are designed for high-performance buffering and clock domain crossing. The series typically offers various capacities and word widths to accommodate different data throughput requirements. These devices are commonly used in networking, industrial automation, and multimedia applications where reliable data synchronization is critical.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the 72V series with matching capacity and speed. Verify if alternative manufacturers offer functionally equivalent synchronous FIFOs with identical pinouts and electrical characteristics.
