Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
Figure 6. Two ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury Devices Configured with Two EPC2 or
EPC1 Configuration Devices
Notes:

(2)
The pull-up resistor should be connected to the same supply voltage as the configuration device.
The diagram shows an ACEX 1K, APEX 20K, FLEX 10K, or Mercury device, which has
MSEL0
and
MSEL1
tied to
ground. For FLEX 6000 devices,
MSEL
is tied to ground, and the
DATA0
pin is named
DATA
. EPC2 cannot be used
with FLEX 6000 devices. All other connections are the same for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and
Mercury devices.
All pull-up resistors are 1 k
(APEX 20KE pull-resistors are 10k
). The
OE
and
nCS
pins on EPC2 devices have
internal, user-configurable 1-k
pull-up resistors. If internal pull-up resistors are used, external pull-up resistors
should not be used on these pins.
The
nINIT_CONF
pin is only available on EPC2 devices and has an internal pull up of 1 k
that is always active. If
nINIT_CONF
is not available or not used,
nCONFIG
must be pulled to V
CC
either directly or through a 1-k
resistor.

FLEX 8000 Device Configuration
FLEX 8000 devices differ from ACEX 1K, APEX 20K, FLEX 10K, and
FLEX 6000 devices in that they have internal oscillators that can provide a
DCLK
signal to the configuration device. The configuration device sends
configuration data out as a serial bitstream on the
DATA
output pin. This
data is routed into the FLEX 8000 device via the
DATA0
input pin. The
EPC1, EPC1441, EPC1213, EPC1064, and EPC1064V configuration devices
support this type of configuration.
