Do not use EPC2 devices to configure FLEX 6000 devices.
Pin-out information for EPC8 and EPC16 configuration devices, please refer to each respective data sheet.
This package is available for EPC1 and EPC1441 devices only.
This package is available for EPC2 and EPC1441 devices only.
The OE, nCS, and nINIT_CONF pins on EPC2 devices have internal, user-configurable 1-kΩ pull-up resistors. If
internal pull-up resistors are used, external pull-up resistors should not be used on these pins.
The EPC1441 device does not support data cascading. EPC2 and EPC1 devices support data cascading.
This pin applies to the EPC2 device only.

Device Configuration with Multiple EPC2 or EPC1 Configuration
Devices
When configuration data for APEX II, APEX 20K, Mercury, ACEX 1K,
and FLEX devices exceeds the capacity of a single EPC2 or EPC1
configuration device, multiple EPC2 or EPC1 devices can be cascaded
together. If multiple EPC2 or EPC1 devices are required, the nCASC and
nCS pins provide handshaking between the devices.
