Device Configuration
APEX 20K, Mercury, ACEX 1K, and FLEX devices can be configured with
EPC4, EPC8, EPC16, EPC2, EPC1, or EPC1441 devices. FLEX 6000 devices
can be configured with EPC1 or EPC1441 devices. APEX II devices can be
configured with EPC2, EPC4, EPC8, and EPC16 devices. The EPC4, EPC8,
EPC16, EPC2, EPC1, or EPC1441 device stores configuration data in its
EPROM array and serially clocks data out with an internal oscillator. The
OE, nCS, and DCLK pins supply the control signals for the address counter
and the output tri-state buffer. The configuration device sends a serial
bitstream of configuration data to its DATA pin, which is routed to the
DATA0 or DATA input pin on the LUT-based PLD device.
an LUT-based PLD configured with a single EPC2, EPC1, or EPC1441
device.
