FLEX 8000 Device Configuration
FLEX 8000 devices differ from ACEX 1K, APEX 20K, APEX II, FLEX 10K,
and FLEX 6000 devices in that they have internal oscillators that can
provide a DCLK signal to the configuration device. The configuration
device sends configuration data out as a serial bitstream on the DATA
output pin. This data is routed into the FLEX 8000 device via the DATA0
input pin. The EPC1, EPC1441, EPC1213, EPC1064, and EPC1064V
configuration devices support this type of configuration.

parameters, see the
The configuration device imposes a POR delay upon initial power-up to allow the
voltage supply to stabilize. Subsequent reconfigurations do not incur this delay.
