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 outputs 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 segments 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 connected 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.

2.1.2 LEDs with
Selectable Jumpers
Atmel CPLD Development/Programmer Board has eight individual LEDs, which allow
designers to display the output signals from the user I/Os of the ATF15xx CPLD. These
eight LEDs are labeled LED1 to LED8 on the Atmel CPLD Development/Programmer
Board. The cathode of each LED is connected to ground through a series resistor while
the anode of each LED is connected to a user I/O pin of the CPLD through the
JPL1/JPL2/PL3/JPL4/JPL5/JPL6/JPL7/JPL8 selectable jumper. These jumpers can be
removed to disable the LEDs by unconnecting the anodes of the LEDs to the I/O pins of
the CPLD. Figure 2-3 shows the circuit diagram of the LEDs with the selection jumpers.
To turn on a particular LED, the corresponding ATF15xx I/O pin connected to the LED
must be in a logic high state with the corresponding jumper set. Hence, the outputs of
the ATF15xx need to be configured as active-high outputs in the design files. These
LEDs work best at 2.5V VCCIO or higher.
The lower pin-count devices (44-pin) only have four I/Os connected to LED1, LED2,
LED3, and LED4. For the higher pin-count devices (100-pin and larger), all eight LEDs
are connected to the I/Os of the device. Tables 2-5, 2-6, 2-7, and 2-8 show the connections of the CPLD I/Os to the LEDs in the different package types.

Atmel CPLD Development/Programmer Board contains eight push-button switches,
which are connected to the I/O pins of the CPLD. They allow designers to send input
logic signals to the user I/O pins of the ATF15xx CPLD. These eight switches are
labeled SW1 to SW8 on the Atmel CPLD Development/Programmer Board. One end of
each input push-button switch is connected to VCCIO while the other end of each pushbutton switch is connected to a pull-down resistor and then connected to the specific I/O
pin of the CPLD through the JPS1/JPS2/JPS3/JPS4/JPS5/JPS6/JPS7/JPS8 selectable
jumper.
If any one of these switches is pressed and the corresponding jumper is set, the specific
I/O pin of the device will be driven to a logic high state by the output of switch circuit.
Since each push-button switch is also connected to a pull-down resistor, the input will
have a logic low state if the switch is not pressed with the corresponding jumper set. If
the push-button jumper is not set, the corresponding pin will be treated as an unconnected pin. Figure 2-4 on page 2-7 is a circuit diagram of the push-button switch and
selectable jumper. Tables 2-9, 2-10, 2-11, and 2-12 show the connections of these eight
push-button switches to the CPLD I/O pins in the different package types.

Atmel CPLD Development/Programmer Board also contains two push-button switches
for the Global Clear (GCLR) and Output Enable (OE1) pins of the CPLD. They allow the
designers to control the logic states of the OE1 and GCLR inputs of the ATF15xx CPLD.
These two switches are labeled SW-GCLR and SW-GOE1 on the Atmel CPLD Development/Programmer Board. One end of the SW-GCLR input push-button switch is
connected to ground (GND). The other end of the push-button switch is connected to a
pull-up resistor to VCCIO, and then connected to the GCLR dedicated input pin of the
ATF15xx. It is intended to be used as an active-low reset signal to reset the registers in
the ATF15xx with the JPGCLR selectable jumper set. Similarly, one end of the SWGOE1 input push-button switch is connected to ground (GND). The other end of the
push-button switch is connected to a pull-up resistor to VCCIO, and then connected to
the OE1 dedicated input pin of the ATF15xx. It is intended to be used as an active-low
output enable signal to control the enabling/disabling of the tri-state output buffers in the
ATF15xx with the JPGOE selectable jumper set. Figure 2-5 on page 2-9 is the circuit
diagram of these two push-button switches and the jumpers for the GCLR and OE1
pins.
If any of these push-button switches is pressed and the corresponding jumper is set,
then the specific I/O of the CPLD will be driven to a logic low state. Since each pushbutton is also connected to a pull-up resistor, the corresponding CPLD input will have a
logic high state if the push-button switch is not pressed with the corresponding selectable jumper set. If the selectable jumper is not set, the corresponding dedicated input
pin of the CPLD can be considered a “no connect” (NC) pin. Table 2-13 on page 2-9

The Clock Selection Jumper, labeled JP-GCLK, on the CPLD Development/Programmer Board is a two-position jumper that allows the users to select which GCLK
dedicated input pin (either GCLK1 or GCLK2) of the ATF15xx should be connected to
the output of the 2 MHz oscillator. In addition, the jumper can be removed to allow an
external clock source to be connected to GCLK1 and/or GCLK2 of the ATF15xx. Figure
2-6 is the circuit diagram of the oscillator and selection jumper. Table 2-14 on page 2-10
shows the pin numbers for the GCLK1 and GCLK2 dedicated input pins of the ATF15xx
in all the different available package types.
Note: If GCLK1 jumper is set, the jumper will be located toward the side of the board.
On the other hand, if GCLK2 jumper is set, the jumper will be located toward the
middle of the board.

The VCCIO and VCCINT Voltage Selection Jumpers, labeled VCCIO Selector and
VCCINT Selector respectively on ATF15xx-DK3 Development/Programming Board,
allow the designers to select I/O supply voltage level (VCCIO) and core supply voltage
level (VCCINT) that are used for the target CPLD on the board. Once these jumpers are
set correctly, the LEDs (labeled VCCINT LED and VCCIO LED) will be turn on as
expected. However, at lower supply voltage levels (i.e. 2.5V or lower), the LEDs might
be very dim.
For ATF15xxAS/ASL (5.0V) CPLDs, both the VCCIO Selector and VCCINT Selector
jumpers MUST BE set to 5.0V. For ATF15xxASV/ASVL (3.3V) CPLDs, both the VCCIO
Selector and VCCINT Selector Jumpers MUST BE set to 3.3V only. For the ATF15xxBE
(1.8V) CPLDs, designers MUST SET VCCINT Selector jumper to 1.8V for its core voltage supply. However, designers can set the VCCIO Selector jumper to 3.3V, 2.5V, or
1.8V (but not 5.0V) in order for the I/Os of the ATF15xxBE CPLD to interface with different voltage levels devices.
Note: The power of the CPLD Development/Programmer Board MUST BE turned
OFF when changing the position of the VCCIO or VCCINT voltage selection
jumper (VCCIO Selector or VCCINT Selector).
2.1.7 ICCIO and ICCINT
Jumpers
The IccIO and IccINT jumpers can be removed and used as Icc measurement points.
When the jumpers are removed, current meters can be connected to the posts to measure the current consumption of the target CPLD. When users are not using these
jumpers to measure the current, these jumpers must be set in order for the board and
CPLD to operate.
2.1.8 Voltage Regulators Two voltage regulators, labeled VR1 and VR2, are used to independently generate and
regulate the VCCINT and VCCIO voltages from the 9V DC power supply. For details,
please review the schematic of the ATF15xx-DK3 board.
2.1.9 Power Supply
Switch and Power
LED
The Power Supply Switch, labeled POWER SWITCH, can be switched to the ON or
OFF position, which is used to turn on or off the power of the ATF15xx-DK3 board
respectively. It allows the 9V DC voltage at the Power Supply Jack to pass to the voltage regulators when it is in the ON position. When the Power Supply Switch is turned
ON, the Power LED (labeled POWER LED) will light up to indicate that the ATF15xxDK3 board is supplied with power.
2.1.10 Power Supply Jack
and Power Supply
Header
The Atmel ATF15xx-DK3 Development/Programmer Board contains two different types
of power supply connectors labeled JPower and JP Power. Either one of these power
supply connectors can be used to connect a 9V DC power source to the board. The first
power connector, labeled JPower, is a barrel power jack with a 2.1mm diameter post
and it mates to a 2.1mm (inner diameter) x 5.5mm (outer diameter) female plug. The
second is the power supply header, labeled JP Power, is a 4-pin male 0.1" header with
0.025" square posts. The availability of these two types of power connectors allows the
users to choose the type of power supply equipment to use for ATF15xx-DK3 Development/Programmer Board. However, please note that only one of these two power
supply connectors should be powered with a 9V DC source but not both at the same
time.

Hardware Description
2.1.11 JTAG ISP Connector
and TDO Selection
Jumper
The JTAG ISP Connector, labeled JTAG-IN, is used to connect the ATF15xx’s JTAG
port pins (TCK, TDI, TMS and TDO) through the ISP download cable to the parallel
printer (LPT) port of a PC for JTAG ISP programming of the ATF15xx. Polarized connectors are used on the ATF15xx-DK3 and ISP Download Cable (ATDH1150VPC) Rev
6.0 or later to minimize connection problems. The PIN1 label at the bottom of the JTAG
ISP connector indicates the pin 1 position of the 10-pin header and further reduces the
chance of connecting the ISP Download Cable incorrectly.
To the left of the JTAG-IN connector, there are two columns of vias and they are labeled
JTAG-OUT. They are intended to allow the users to create a JTAG daisy chain to perform JTAG operations to multiple devices. Users will need to solder the same type of
connector as the one used for JTAG-IN into the JTAG-OUT position in order to utilize
this available feature.
To create a JTAG daisy chain using multiple ATF15xx-DK3 boards, the TDO Selection
Jumper, labeled JP-TDO, must be set to the appropriate position. For all the devices in
the daisy chain except the last device, this jumper must be set to the “TO NEXT
DEVICE” position. For the last device in the chain, this jumper must be set to the “TO
ISP CABLE” position. When this jumper is in the “TO NEXT DEVICE” position, the TDO
of that particular JTAG device will be connected to the TDI of the next JTAG device in
the chain. When this jumper is in the “TO ISP CABLE” position, the TDO of that device
will be connected to the TDO of the JTAG 10-pin connector, which will allow the TDO
signal of the that device in the chain to be transmitted back to the host PC with the ISP
software. Figure 2-7 below is a circuit diagram of the JTAG connectors and the JP-TDO
jumper. Table 2-15 on page 2-12 lists the pin numbers of the four JTAG pins for the
ATF15xx in all the available packages.
For a single device setup, the position of the JP-TDO jumper must be set to “TO ISP
CABLE”.

Atmel ATF15xx-DK3 CPLD Development/Programmer Socket Adapter Boards
(ATF15xx-DK3-XXXXX) are circuit boards that interface with the Atmel ATF15xx-DK3
CPLD Development/Programmer Board. They are used in conjunction with the
ATF15xx-DK3 CPLD Development/Programmer Board to evaluate/program Atmel
ATF15xx ISP CPLDs with different package types. At press time, there are four Socket
Adapter Boards available for the ATF15xx-DK3 covering the 44-TQFP, 44-PLCC, 84-
2-12 ATF15xx-DK3 Development Kit User Guide
3605B–PLD–05/06
Hardware Description
PLCC, and 100-TQFP package types in the ATF15xx family of CPLDs. Socket Adapter
boards for other packages will become available in the near future.
Each socket adapter board contains a socket for the Atmel ATF15xx device and with
male headers on the bottom side, labeled JP1 and JP2. The headers on the bottom side
mate with the female headers on the ATF15xx-DK3 board, labeled JP4 and JP3. The
four 7-segment displays, push-button switches, JTAG port signals, oscillator, VCCINT,
VCCIO, and GND on the CPLD Development/Programmer Board are connected to the
ATF15xx device on the Socket Adapter Board through these two sets of connectors.
On the top of the 44-TQFP socket adapter, there are four 10-pin connectors with the
same dimensions as the JTAG ISP connector. The pins of these four connectors are
connected to the input and I/O pins (except the four JTAG pins) of the target CPLD
device. They can be used to connect to an oscilloscope or logic analyzer to capture the
activities of the input and I/O pins of the CPLD. They also can be used to connect the
input and I/O pins of the CPLD to other external boards or devices for system level evaluation or testing.
2.3 Atmel CPLD ISP
Download Cable
The Atmel CPLD ISP Download Cable (P/N: ATDH1150VPC) connects the parallel
printer (LPT) port of your PC to the 10-pin JTAG header on the Atmel CPLD Development/Programmer Board or a custom circuit board. This is shown in Figure 2-10 on
page 2-14. This ISP cable acts as a buffer to buffer the JTAG signals between the PC’s
LPT port and the ATF15xx on the circuit board. The Power-On LED on the back of the
25-pin male connector housing indicates that the cable is connected properly. Make
sure this LED is turned on before using the Atmel CPLD ISP Software (ATMISP).
This ISP cable consists of a 25-pin (DB25) male connector, which is connected to the
LPT port of a PC. The 10-pin female plug connects to the 10-pin male JTAG header on
the ISP circuit board. The red color stripe on the ribbon cable indicates the orientation of
Pin 1 of the female plug. The 10-pin male JTAG header on the CPLD Development/Programmer Board is polarized to prevent users from inserting the female plug in the wrong
orientation.
The Atmel CPLD Development/Programmer kits includes an Atmel ISP cable; however,
other supported ISP cables can also be used. The use of the ISP cable on Atmel development kit is depending on the device that is selected.
The following shows the appropriate ISP cable that can be used for the different voltage
families of Atmel CPLDs.
1. Atmel-ISP Cable (Rev 4.0 or earlier) can be used for ATF15xxAS/ASL (5.0V)
device only.
2. Atmel-ISP Cable (Rev 5.0) can be used for ATF15xxAS/ASL (5.0V) or
ATF15xxASV/ASVL (3.3V) device only.
3. Atmel-ISP Cable (Rev 6.0), also known as the “Atmel CPLD-ISP MV Cable”,
can be used for ATF15xxAS/ASL (5.0V) or ATF15xxASV/ASVL (3.3V) or
ATF15xxBE (1.8V core) device.
4. ByteBlaster ISP Cable can be used for ATF15xxAS/ASL (5.0V) device only.
5. ByteBlasterMV ISP Cable can be used for ATF15xxAS/ASL (5.0V) or
ATF15xxASV/ASVL (3.3V) device only.
6. ByteBlaster II ISP Cable can be used for ATF15xxAS/ASL (5.0V) or
ATF15xxASV/ASVL (3.3V) or ATF15xxBE (1.8V core) device.

7. Connect the DB25 side of the Atmel CPLD ISP MV cable (Revision 6) to the PC’s
parallel port and the 10-pin header side of the cable to the Atmel ATF15xx-DK3
CPLD Development Board as shown Figure 2-10 on page 2-14.
8. Connect a 9V AC/DC power supply to the power connector (JPower) of the Atmel
ATF15xx-DK3 CPLD Development/Programmer Board.
9. Set the VCCIO Selector jumper to the 1.8V(BE) position for supplying the core
voltage of the ATF1502BE device at 1.8V, then set the VCCINT Selector jumper
to the 1.8V(BE) position for supplying the I/O pad voltage of the ATF1502BE
device at 1.8V.
Note: Make sure the ICCINT and ICCIO jumpers are in their default positions. These
two jumpers are only removed when you are connecting them from two poles of
the digital multimeter to perform current measurement.
10. Set the JPCLK jumper to GCLK1 so that the output of the crystal oscillator will go
to pin 37 (GCLK1) of the ATF1502BE. For this design, you can also set the
JPCLK jumper to GCLK2 so that the output of the crystal oscillator will go to pin
40 (GCLK2) of the ATF1502BE for selecting another global clock source.
11. Set the JPJTAG Jumper ISP Cable position, which is toward the middle of the
board.
12. Connect the 44-pin TQFP Socket Adapter Board onto the main development/programmer board.
Note: If a device in a different package type is to be programmed, then the appropri-
ate Socket Adapter Board must be used.
13. Select which LPT port is being used for Atmel CPLD ISP cable in the Port Setting
field. LPT1 is the default port and it represents address 0x378.
14. Select the ISP download cable type in the Cable Type field. The default cable
