EPC1 and EPC1441 devices can replace the EPC1213, EPC1064, and
EPC1064V configuration devices. The EPC1 or EPC1441 device
automatically emulates the EPC1213, EPC1064, or EPC1064V when it is
programmed with the appropriate POF. When the EPC1 or EPC1441
device is programmed with an EPC1213, EPC1064, or EPC1064V POF, the
FLEX 8000 device drives the EPC1 or EPC1441 device’s OE pin high and
clocks the EPC1 or EPC1441 device. One EPC1 device can store more
configuration data than the EPC1064, EPC1064V, EPC1213, or EPC1441
device. Therefore, designers can use one type of configuration device for
all FLEX devices. In addition, a single EPC1 or EPC1441 device can
configure any FLEX 8000 device.
For multi-device configuration of FLEX 8000 devices, the nCASC and nCS
pins provide handshaking between multiple configuration devices,
allowing several cascaded EPC1 or EPC1213 devices to serially configure
multiple FLEX 8000 devices. The EPC1441, EPC1064, and EPC1064V do
not support data cascading.
configured with a single EPC1, EPC1441, EPC1213, EPC1064, or
EPC1064V configuration device.
