25 / 52 page  Altera Corporation 25 FLEX 6000 Programmable Logic Device Family Data Sheet Figure 14. IOE Connection to Column Interconnect SameFrame Pin-Outs 3.3-V FLEX 6000 devices support the SameFrame pin-out feature for FineLine BGA packages. The SameFrame pin-out feature is the arrangement of balls on FineLine BGA packages such that the lower-ball- count packages form a subset of the higher-ball-count packages. SameFrame pin-outs provide the flexibility to migrate not only from device to device within the same package, but also from one package to another. A given printed circuit board (PCB) layout can support multiple device density/package combinations. For example, a single board layout can support an EPF6016A device in a 100-pin FineLine BGA package or an EPF6024A device in a 256-pin FineLine BGA package. The Altera software packages provide support to design PCBs with SameFrame pin-out devices. Devices can be defined for present and future use. The Altera software packages generate pin-outs describing how to lay out a board to take advantage of this migration (see Figure 15). Row Interconnect Column Interconnect Each IOE can drive two column interconnect channels. Each IOE data and OE signal is driven to a local interconnect. Any LE can drive a pin through the row and local interconnect. IOE IOE LAB FastFLEX I/O: An LE can drive a pin through a local interconnect for faster clock-to-output times. |
