Description
The Atmel ATDH40M prototyping system allows designers to quickly and economi-
cally evaluate Atmel's fam ily of AT40K/AT40KAL FPGA and AT94K Field
Programmable System Level Integrated Circuit (FPSLIC
TM
) devices and Atmel's AT17
FPGA configuration memory devices. The ATDH40M board connects to any x86 PC
via parallel port through a 10-pin header cable to program the AT40K/AT40KAL
FPGA/AT94K FPSLIC, or through a parallel port cable to program the AT17 FPGA
Configuration EEPROMs. The motherboard interfaces with various daughter boards
in order to program different package footprints (see Table 1).

The AT40K/AT40KAL FPGA devices are pin-compatible in
a given package footprint across the family. See Table 2 for
compatibility listings. The 208PQFP, for example, will sup-
port all AT40K family members.
FPSLIC is pin-compatible with AT40K/AT40KAL device
families and is supported by the ATDH40M Prototyping
System.
Note:
1. Daughtercard not available for ATDH40M.
2. Not all devices are available in all package options. Please check appropriate datasheet for a list of valid part/package
combinations.
Programming Setup
Figure 1 on page 3 is the board layout of the ATDH40M motherboard. Figure 2 shows the typical daughter board. To con-
nect the two boards together, the daughter board fits on top of the motherboard by aligning the two arrows together. The
two boards will only fit one way.

Power Configuration
Power for the motherboard can come from two sources. It
can be supplied by either the jack inputs J1 and J2, or by a
9V power input P1. The source that will drive the mother-
board is determined by switch SW3. Power supplied by the
jacks uses the external setting. Power supplied by the
9V source uses the internal setting. Voltage on the
motherboard for the latter setting is regulated by switch
SW2. LV parts use the 3.3V setting while the rest use the
5.0V setting. The LED L1 will light up only when power is
correctly supplied to VCC. Table 3 lists the possible
configurations. AT40KAL and AT94KAL devices must use
3.5V power setting.
Program/Boot Settings
Switches SW4 and SW5 determine the program and boot
settings for the ATDH40M. They are located on the bottom
left corner. Table 4 lists the switch combinations and their
effects. SW4 controls the SEREN signal line of the mother-
board to the 2:1 multiplexer (device U3) and the AT17
(device U1). SW% connects signal D0 from the PSLI
device to either the AT17 configuration memory device only
(down) or to the PC interface (up).

Programming the AT40K FPGA Device
When SW4 and SW5 are set to up, the PSLI device can be
programmed by the PC parallel interface. The ATDH40M
interfaces with the PC through the 10-pin header socket H1
located on the bottom right corner. Programming the FPGA
is not possible by using the parallel port interface on the
motherboard. Located below the header H1 are the mode-
select dip-switches DIP-SW1. These control the mode set-
tings for the PSLI device (switches M0, (M1), M2). The
modes directly supported by the motherboard are only
Slave Serial and Master Serial. Programming the AT40K
FPGA from the PC can be achieved from the IDS desktop
or by using the software downld40.exe. Both tools accept
ASCII bitstream files generated by the IDS software (.BST).
Programming the AT17 Configuration
Memory Device
When SW4 is set to down and SW5 is set to up, the AT17
FPGA configuration memory can be programmed by the
parallel port interface located on the top left corner.
Programming the AT17 FPGA Configuration EEPROM is
not possible by using the 10-pin header H1. Programming
the AT17 FPGA Configuration EEPROM from the PC can
be achieved from the IDS desktop or by using the Configu-
rator Programming System (CPS) software supplied by the
IDS software.This software accepts the ASCII bitstream
files (.BST) generated by IDS.
Programming the PSLI Device Using
the AT17 Configuration Memory
When SW4 is set to up and SW5 is set to down, the AT17
Configurator can program the FPGA in Master Serial. To
ensure reliable system power-up, set jumper JMP1
(located below the Configurator socket). The Configurator
must be programmed prior to this setup.
Troubleshooting
1.
Check that the motherboard is connected to the PC
either through the parallel port or through the 10-pin
header.
2.
Check that the motherboard has power (SW1) and
the power configuration switches SW2 and SW3
are correct.
3.
Make sure programming configuration switches
SW4 and SW5 are correct.
4.
Verify that the daughter card is inserted correctly
and that it receives power.
5.
Verify that the PSLI device and/or the PSLI.
Configurator are placed in their sockets correctly.
6.
Set the mode switches before downloading to
the PSLI Device.
7.
Set the GCLK/FCLK jumpers before verifying
PSLI logic.
