7285L15PAI

FIFOs Memory Overview

The Renesas Electronics Corporation 7285L15PAI is an asynchronous FIFO memory integrated circuit designed for high-speed data buffering and rate matching applications. It features a storage capacity of 144K bits, organized as 8K words by 9 bits multiplied by two independent buffers. The device supports unidirectional data transfer with a maximum data rate of 40MHz and a typical access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 150mA. The component is housed in a 56-pin TSSOP surface-mount package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

FIFOs Memory Feature Summary

• Asynchronous dual-buffer architecture supporting simultaneous independent read and write operations
• Unidirectional data flow capability optimized for multiprocessing and rate buffer scenarios
• Integrated relay capability allowing flexible signal routing and loopback testing
• Supports user-defined parity bit configuration within the 9-bit wide data array

FIFOs Memory Applications

• Multiprocessing systems requiring temporary data storage between disparate clock domains
• Rate buffering interfaces where input and output data rates differ significantly
• Data communications equipment utilizing parity checking for error detection
• Industrial control systems needing reliable asynchronous memory buffering

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the datasheet indicates non-compliance. Validate package integrity upon receipt, ensuring no damage to the 56-TSSOP leads. Check manufacturing date codes against project longevity plans. Ensure replacement strategies are documented given the discontinuation notification.

FIFOs Memory Selection Notes

Select this component when asynchronous operation with 15ns access speed is required for 9-bit data paths. Consider the 56-TSSOP package constraints for PCB layout and thermal management. Evaluate the 4.5V to 5.5V supply requirement against system power rails. Assess the 150mA current consumption against available power budget. Verify that unidirectional data flow meets the specific application logic requirements.
