40MX and 42MX FPGA Families

Actel Corporation 

40MX and 42MX FPGA Families

The 42MX devices contain three types of logic modules:

combinatorial (C-modules), sequential (S-modules) and

decode (D-modules). Figure 1-2 illustrates the

combinatorial logic module. The S-module, shown in

Figure 1-3, implements the same combinatorial logic

function as the C-module while adding a sequential

element. The sequential element can be configured as

either a D-flip-flop or a transparent latch. The S-module

register can be bypassed so that it implements purely

combinatorial logic.
