Altera Corporation
SameFrame
Pin-Outs
MAX 7000A 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 EPM7128AE device in a 100-pin
FineLine BGA package to an EPM7512AE device in a 256-pin
FineLine BGA package.
The Altera design software provides support to design PCBs with
SameFrame pin-out devices. Devices can be defined for present and future
use. The software generates pin-outs describing how to lay out a board to
take advantage of this migration (see
