Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the part matches the specified 44-pin PLCC package and speed grade. Ensure handling procedures account for the device's sensitivity to electrostatic discharge during installation.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require 32 macrocells and 34 I/Os within a 44-pin footprint. The -7 speed grade provides 4.5-ns delay suitable for high-frequency applications up to 227.3 MHz. Consider alternative packages like TQFP if surface-mount lead profiles differ from PLCC requirements.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A family, which offers low-cost, high-density programmable logic solutions. The family ranges from 600 to 10,000 usable gates, supporting various package types including PLCC, PQFP, and TQFP to accommodate different pin count and form factor needs.

Complex Programmable Logic Devices Replacement Considerations
