16 / 46 page 16 Altera Corporation MAX 9000 Programmable Logic Device Family Data Sheet Figure 9. MAX 9000 Column-to-IOC Connections Dedicated Inputs In addition to the general-purpose I/O pins, MAX 9000 devices have four dedicated input pins. These dedicated inputs provide low-skew, device- wide signal distribution to the LABs and IOCs in the device, and are typically used for global clock, clear, and output enable control signals. The global control signals can feed the macrocell or IOC clock and clear inputs, as well as the IOC output enable. The dedicated inputs can also be used as general-purpose data inputs because they can feed the row FastTrack Interconnect (see Figure 2 on page 7). I/O Cells Figure 10 shows the IOC block diagram. Signals enter the MAX 9000 device from either the I/O pins that provide general-purpose input capability or from the four dedicated inputs. The IOCs are located at the ends of the row and column interconnect channels. 48 Each IOC is driven by a 17-to-1 multiplexer. Each IOC can drive up to two column channels. 17 17 Column FastTrack Interconnect IOC10 IOC1 48 48 |
