Description  
Xilinx introduces the XC18V00 series of in-system program-  
mable configuration PROMs (Figure 1). Devices in this 3.3V  
family include a 4-megabit, a 2-megabit, a 1-megabit, a  
When the FPGA is in Master-SelectMAP mode, the FPGA  
generates a configuration clock that drives the PROM.  
When the FPGA is in Slave-Parallel or Slave-SelectMAP  
Mode, an external oscillator generates the configuration  
clock that drives the PROM and the FPGA. After CE and OE  
are enabled, data is available on the PROMs DATA (D0-D7)  
pins. New data is available a short access time after each  
rising clock edge. The data is clocked into the FPGA on the  
following rising edge of the CCLK. Neither Slave-Parallel  
nor SelectMAP utilize a Length Count, so a free-running  
oscillator can be used in the Slave-Parallel or Slave-  
SelecMAP modes.  
512-Kbit, and  
a
256-Kbit PROM that provide an  
easy-to-use, cost-effective method for re-programming and  
storing large Xilinx FPGA or CPLD configuration bitstreams.  
When the FPGA is in Master Serial mode, it generates a  
configuration clock that drives the PROM. A short access  
time after CE and OE are enabled, data is available on the  
PROM DATA (D0) pin that is connected to the FPGA D  
IN  
pin. New data is available a short access time after each ris-  
ing clock edge. The FPGA generates the appropriate num-  
ber of clock pulses to complete the configuration. When the  
FPGA is in Slave Serial mode, the PROM and the FPGA are  
clocked by an external clock.  
Multiple devices can be concatenated by using the CEO  
output to drive the CE input of the following device. The  
clock inputs and the DATA outputs of all PROMs in this  
chain are interconnected. All devices are compatible and  
can be cascaded with other members of the family or with  
the XC17V00 one-time programmable Serial PROM family.
