Notes:
(1) The EPC1441, EPC1064, and EPC1064V devices do not support data cascading. The EPC2, EPC1, and EPC1213
devices support data cascading.
(2) The OE pin is a bidirectional open-drain pin.

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
1
A mixture of ACEX 1K, APEX 20K, APEX 20KE, and Mercury
devices can be configured in the same chain. A mixture of
FLEX 10K, FLEX 10KA, FLEX 10KE, and 5.0-V and 3.3-V
FLEX 6000 devices can be configured in the same chain. See
Configuration Chain with Multiple Voltage Levelson page 19.

Notes:
(1) The pull-up resistor should be connected to the same supply voltage as the configuration device.
(2) 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.
(3) All pull-up resistors are 1 k¾ (APEX 20KE pull-resistors are 10k¾). The OE and nCS pins on EPC2 devices have
internal, user-configurable 1-k¾ pull-up resistors. If internal pull-up resistors are used, external pull-up resistors
should not be used on these pins.
(4) The nINIT_CONF pin is only available on EPC2 devices and has an internal pull up of 1 k¾ that is always active. If
nINIT_CONF is not available or not used, nCONFIG must be pulled to VCC either directly or through a 1-k¾ resistor.
Figure 6 shows two ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or
Mercury devices configured with two EPC2 or EPC1 devices.
