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

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

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.
