7281L12PA

FIFOs Memory Overview

The Renesas Electronics Corporation 7281L12PA is a dual asynchronous FIFO memory device housed in a 56-pin TSSOP package. It features two independent 256 x 9-bit memory arrays, providing a total storage capacity of 4.6K bits. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 50 MHz with an access time of 12 ns. Designed for multiprocessing and rate buffering applications, it allows simultaneous read and write operations without requiring external control logic for basic functionality.

FIFOs Memory Feature Summary

• Dual independent FIFO structures enabling simultaneous data handling
• Asynchronous operation supporting rate matching between different clock domains
• Configurable 9-bit word width allowing user-defined parity or control bits

FIFOs Memory Applications

• Multiprocessing systems requiring data buffering
• Rate buffer applications for clock domain crossing
• Data communications systems needing error checking via parity bits

FIFOs Memory Procurement Notes

Verify end-of-life status and obsolescence notices before procurement planning. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for RoHS compliance restrictions as the component may not meet current environmental standards. Validate pin compatibility and electrical specifications against target system designs prior to integration.

FIFOs Memory Selection Notes

Select this component when dual asynchronous FIFOs are required for parallel data paths. Ensure the 5.0 V operating voltage aligns with the system power rails. Consider the 56-pin TSSOP package constraints for PCB layout. Verify that the 12 ns access time meets the timing requirements of the connected processors or controllers.

FIFOs Memory Part Context

This part belongs to the 7280 series of dual asynchronous FIFOs from Renesas Electronics. It is designed for high-speed data buffering in complex digital systems. The series provides reliable first-in-first-out memory management for applications requiring temporary data storage during processing transitions.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the 7280 series. Evaluate alternative dual FIFO devices with similar 256x9 configurations. Verify if newer generations offer improved speed or lower power consumption while maintaining functional equivalence.
