Configuration Devices for SRAM-based LUT Devices Data Sheet
Figure 5. APEX II, APEX 20K, Mercury, ACEX 1K, FLEX 10K, or FLEX 6000 Device Configured with Two EPC2
or EPC1 Configuration Devices
Note (1)
Notes to
Figure 5
:
(1)
Do not use EPC2 devices to configure FLEX 6000 devices.
(2)
The pull-up resistor should be connected to the same supply voltage as the configuration device.
(3)
All pull-up resistors are 1 k
(APEX 20KE pull-resistors are 10 k
). 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.
(4)
The diagram shows an APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 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
. EPC8, EPC16,
and EPC2 devices cannot be used with FLEX 6000 devices. All other connections are the same for FLEX 6000
devices. The Quartus II software uses the internal pull-up resistors by default. To turn off the internal pull-up
resistors, check the
Disable nCS and OE pull-ups on configuration device
option when generating programming files.
(5)
EPC4, EPC8, and EPC16 devices cannot be cascaded.
(6)
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.
