72801L15PF

FIFOs Memory Overview

The Renesas 72801L15PF is a synchronous dual FIFO memory device housed in a 64-pin TQFP package. It provides two independent 256 x 9 bit memory arrays, supporting bidirectional data transfer at a maximum clock frequency of 66.7 MHz with a 10 ns access time. The component operates on a 4.5 V to 5.5 V supply and draws a maximum current of 75 mA. It features programmable flags, First Word Fall Through (FWFT) support, and retransmit capability within an industrial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Dual independent synchronous FIFO architectures with separate control lines for each bank
• Bidirectional data bus operation allowing flexible read/write direction control
• Programmable status flags including empty, full, and almost-empty/full indicators
• First Word Fall Through (FWFT) functionality for reduced latency

FIFOs Memory Applications

• Data buffering between asynchronous system domains
• Rate matching in high-speed digital communication interfaces
• Priority-based data handling in multiprocessing systems
• Width or depth expansion configurations for larger memory requirements

FIFOs Memory Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Ensure that any substitute part maintains pin compatibility and functional equivalence to avoid redesign efforts. Confirm moisture sensitivity level and RoHS compliance status before integration into new production cycles.

FIFOs Memory Selection Notes

Select this part when a dual-channel synchronous FIFO with bidirectional capability is required. It is suitable for applications needing simultaneous independent operations on two 9-bit wide data paths. Consider the 64-pin TQFP package constraints and 5V logic levels. Verify that the 66.7 MHz speed meets system timing requirements and that the industrial temperature range aligns with environmental conditions.

FIFOs Memory Part Context

The 72801L15PF belongs to the Renesas 72801 series of SuperSync FIFO memories. This family is designed for high-performance data buffering and rate conversion tasks. The device integrates two identical FIFO banks into a single package, offering design flexibility for complex data flow management without requiring multiple discrete components.
