XQ18V04VQG44C FPGAs Overview
Xilinx introduces the QPro XQ18V04VQG44C Military Grade 4Mbit
in-system programmable configuration Flash PROM. The XQ18V04VQG44C is a 3.3V rewritable PROM that
provides a reliable non-volatile method for storing large Xilinx FPGA configuration bitstreams used in systems that
require operation over the full military temperature range.
When the FPGA is in Master Serial mode, it generates a
configuration clock that drives the PROM. A short access
time after the rising CCLK, data is available on the PROM
DATA (D0) pin that is connected to the FPGA DIN pin.
FPGA generates the appropriate number of clock pulses to
complete the configuration. When the FPGA is in Slave
Serial mode, the PROM and the FPGA are clocked by an
When the FPGA is in SelectMAP mode (Slave), an external
oscillator will generate the configuration clock that drives
the PROM and the FPGA. After the rising CCLK edge, data
is available on the PROMs DATA (D0-D7) pins. The data will
be clocked into the FPGA on the following rising edge of the
CCLK. Multiple devices can be cascaded 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. The XQ18V04VQG44C is compatible and can be
cascaded with other configuration PROMs such as the
XQR1701L and XQR17V16 one-time programmable configuration PROMs.
