Hardware Description
2.1.1

7-segment Displays
with Selectable
Jumpers
Atmel CPLD Development/Programmer Board contains four seven-segment displays to
allow the designers to observe the outputs of the ATF15xx CPLD. These four displays
are labeled DSP1, DSP2, DSP3, and DSP4, and have common anode LEDs with the
common anode lines connected to VCCIO (I/O supply voltage for the CPLD) through
series resistors with selectable jumpers labeled JPDSP1, JPDSP2, JPDSP3, or
JPDSP4. These jumpers can be removed to disable the displays by unconnecting the
VCCIO to the displays. Individual cathode lines are connected to the I/O pins of the
ATF15xx CPLD on the CPLD Development/Programmer Board. To turn on a particular
segment including the DOT of a display, the corresponding ATF15xx I/O pin connected
to this LED segment must be in a logic low state with the corresponding selectable
jumper set. Hence, the outputs of the ATF15xx need to be configured as active-low out-
puts in the design file. These displays work best at 2.5V VCCIO or higher.
Each segment of each display is hard-wired to one specific I/O pin of the ATF15xx. For
the higher pin count devices (100-pin and larger), all seven segments and the DOT seg-
ments of the four displays are connected to the I/O pins of the ATF15xx. However, for
the lower pin count devices, only a subset of the displays (1st and 4th displays) are con-
nected to the ATF15xx’s I/O pins. Tables 2-1, 2-2, 2-3, and 2-4 show the connections for
7-segment displays to the ATF15xx in different package types. The circuit schematic of
the displays and jumpers is shown in Figure 2-2.
