Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance and lead times as availability varies. Ensure ESD handling protocols are followed during installation. Check for specific suffix variations that may indicate temperature grades or packaging differences.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macrocells and 192 I/Os are required in a 256-pin BGA footprint. Compare against LC4384V or LC4384Z variants if higher voltage tolerance or extended temperature ranges are needed. Ensure design tools support the ispMACH 4000C architecture for optimal timing closure.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4000C series, designed for low-power, high-performance CPLD applications. It succeeds earlier ispLSI and ispMACH 4000 families, offering improved density and speed. The 'C' suffix denotes the 1.8V core voltage variant, distinct from the 3.3V (V) or 2.5V (B) versions.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Consider LC4384V-35FT256C if voltage levels allow, or LC4384Z-35FT256C for automotive-grade requirements. Verify logic capacity and I/O count compatibility before substitution.
