SameFrame
Pin-Outs
ACEX 1K 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 a range of devices from an EP1K10 device in a 256-pin
FineLine BGA package to an EP1K100 device in a 484-pin FineLine BGA
package.
The Altera software provides support to design PCBs with SameFrame
pin-out devices. Devices can be defined for present and future use. The
Altera software generates pin-outs describing how to lay out a board that
takes advantage of this migration. Figure 18 shows an example of
SameFrame pin-out.
Figure 18. SameFrame Pin-Out Example
Table 10 shows the ACEX 1K device/package combinations that support
SameFrame pin-outs for ACEX 1K devices. All FineLine BGA packages
support SameFrame pin-outs, providing the flexibility to migrate not only
from device to device within the same package, but also from one package
to another. The I/O count will vary from device to device.
