Pin-Outs

MAX 7000A Programmable Logic Device Data Sheet

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 Figure 7).
