N82077AA1

Controllers Overview

The N82077AA1 is a legacy controller interface component manufactured by Altera, now part of Intel. It is housed in a 68-pin PLCC package and classified under the Controllers category within integrated circuits. The device is designated as an obsolete product within the manufacturer's portfolio, indicating it is no longer actively produced or supported for new designs.

Controllers Feature Summary

• Functions as a dedicated controller interface solution
• Utilizes a 68-lead Plastic Leaded Chip Carrier (PLCC) surface-mount package
• Designed for integration into legacy system architectures

Controllers Applications

• Legacy floppy disk drive controller implementations
• Historical embedded system data storage interfaces
• Maintenance of older industrial control hardware

Controllers Procurement Notes

This component is officially listed as a legacy or obsolete product by the manufacturer. Availability is restricted to existing stock from authorized distributors or third-party surplus markets. Buyers must verify the authenticity and physical condition of units carefully, as these parts are no longer in active production. Supply chain stability cannot be guaranteed, and lead times may vary significantly depending on source inventory levels.

Controllers Selection Notes

Engineers should consider this part only for maintenance or repair of existing systems requiring exact hardware compatibility. New designs should utilize modern replacement components due to the discontinuation status. Verify that the 68-PLCC footprint matches the target PCB layout. Ensure that software drivers and firmware support remain available for the specific interface requirements of the legacy application.

Controllers Part Context

Altera, acquired by Intel, primarily specializes in programmable logic devices such as FPGAs and SoCs. The N82077AA1 represents a niche controller interface product from their broader historical portfolio. This component belongs to a class of specialized interface chips used before standardization on more versatile programmable logic solutions became dominant in consumer and industrial electronics.

Controllers Replacement Considerations

No public confirmed substitute part numbers are documented for this specific legacy controller. Engineers must evaluate generic interface controllers or re-implement the functionality using modern FPGA families if redesigning the system. Direct pin-to-pin replacements are not officially specified by the manufacturer.
