7284L15PAI

FIFOs Memory Overview

The Renesas Electronics Corporation 7284L15PAI is a CMOS dual asynchronous FIFO integrated circuit. It provides two independent 4K x 9 memory arrays within a single package, offering a total storage capacity of 72 kilobits. The device supports bidirectional data transfer with separate control and data lines for each FIFO. It operates on a single 5V supply voltage, ranging from 4.5V to 5.5V, and features a maximum data rate of 40MHz with an access time of 15ns. The component is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• Dual independent FIFO architecture allowing simultaneous operation of two separate 4K x 9 memory banks
• Bidirectional data flow capability with dedicated control and data lines for each FIFO channel
• CMOS technology ensuring low power consumption suitable for high-density applications

FIFOs Memory Applications

• Multiprocessing systems requiring efficient data buffering between processors
• Rate matching buffers for asynchronous communication interfaces
• Data acquisition systems needing temporary storage before processing

FIFOs Memory Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance if required by your design specifications. Confirm RoHS status as legacy components may vary. Check current manufacturer lifecycle status as this part may be discontinued or subject to last-time buy restrictions. Ensure pin compatibility with existing PCB layouts before procurement.

FIFOs Memory Selection Notes

Select this component when dual independent asynchronous buffering is required in a compact footprint. The 9-bit width accommodates parity bits for error checking in serial communications. Consider the 15ns access time against system clock speeds. Verify that the TQFP-64 package fits the available board space and thermal requirements compared to alternative packages like TSSOP.

FIFOs Memory Part Context

This part belongs to the 7284 series of dual synchronous/asynchronous FIFOs from Renesas. It is functionally similar to other parts in the 7200 family but offers specific timing characteristics. The 7284 variant typically denotes asynchronous operation, distinguishing it from the 72841 synchronous counterpart. It serves as a core memory interface solution for legacy and specialized industrial designs.

FIFOs Memory Replacement Considerations

Direct substitutes include the IDT7284L15PAI. Other compatible options within the same family are the 7284L15PF or 7284L15TF depending on package preference. Verify electrical parameters match exactly before substitution.
