Configuration Devices for SRAM-based LUT Devices Data Sheet
Notes to
Figure 6
:
(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. 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. 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.
(3)
The diagram shows an APEX II, APEX 20K, Mercury, ACEX 1K, or FLEX 10K 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 FLEX 6000 devices.
(4)
EPC4, EPC8, and EPC16 devices cannot be cascaded.
(5)
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.
(6)
To ensure successful configuration between APEX 20KE and configuration devices in all possible power-up
sequences, pull up
nCONFIG
to V
CCINT
.
(7)
This diagram is for APEX 20KE devices only.
(8)
To isolate the 1.8-V and 3.3-V power supplies when configuration APEX 20KE devices, add a diode between the
APEX 20KE device’s
nCONFIG
pin and the configuration device’s
nINIT_CONF
pin. Select a diode with a threshold
voltage (V
T
) less than or queal to 0.7 V. The diode will make the
nINIT_CONF
pin an open-drain pin; the pin will
only be able to drive low or tri-state.

For more information on APEX 20K, ACEX 1K, FLEX 10K, or FLEX 6000
device configuration, see
Application Note 116 (Configuring ACEX 1K,
APEX 20K, FLEX 10K & FLEX 6000 Devices)
.
Figure 7
shows the timing waveform for the configuration device scheme.

Notes to
Figure 7
:
(1)
The configuration devivce will drive DATA low after configuration.
(2)
APEX II and APEX 20K devices (except EP2A70 devices) enter user mode 40 clock cycles after
CONF_DONE
goes
high. EP2A70 devices enter user mode 72 clock cycles after
CONF_DONE
goes high. FLEX 10K and FLEX 6000 devices
enter user mode 10 clock cycles after
CONF_DONE
goes high. Mercury devices enter user mode 136 clock cycles after
CONF_DONE
goes high.
