Xilinx FPGAs and Compatible PROMs
Controlling PROMs
Connecting the FPGA device with the PROM:
The DATA output(s) of the of the PROM(s) drives the
DIN input of the lead FPGA device.
The Master FPGA CCLK output drives the CLK input(s)
of the PROM(s).
The CEO output of a PROM drives the CE input of the
next PROM in a daisy chain (if any).
The RESET/OE input of all PROMs is best driven by
the INIT output of the lead FPGA device. This
connection assures that the PROM address counter is
reset before the start of any (re)configuration, even
when a reconfiguration is initiated by a VCC glitch.
Other methods—such as driving RESET/OE from LDC
or system reset—assume the PROM internal power-
on-reset is always in step with the FPGA’s internal
power-on-reset. This may not be a safe assumption.
The PROM CE input can be driven from either the LDC
or DONE pins. Using LDC avoids potential contention
on the DIN pin.
The CE input of the lead (or only) PROM is driven by
the DONE output of the lead FPGA device, provided
that DONE is not permanently grounded. Otherwise,
LDC can be used to drive CE, but must then be
unconditionally High during user operation. CE can
also be permanently tied Low, but this keeps the DATA
output active and causes an unnecessary supply
current of 10 mA maximum.

Notes:
1.
The suggested PROM is determined by compatibility with the
higher configuration frequency of the Xilinx FPGA CCLK.
Designers using the default slow configuration frequency (CCLK)
can use the XC1765E or XC1765EL for the noted FPGA devices.
