Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000V/B/C/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'B' suffix indicates a 2.5V core voltage variant, distinct from the 1.8V (C) or 3.3V (V) versions. The FTN256 package denotes a 17x17mm FineLine BGA with 0.8mm pitch.

Complex Programmable Logic Devices Replacement Considerations

Compatible replacements include other members of the ispMACH 4000V/B/C/Z family with equal or higher macrocell counts, such as LC4512B variants. Ensure voltage compatibility (2.5V core) and pinout retention when selecting substitutes.
