Signals
There are two kinds of pins that are used to configure
Spartan-II devices: Dedicated pins perform only specific
configuration-related functions; the other pins can serve as
general purpose I/Os once user operation has begun.
The dedicated pins comprise the mode pins (M2, M1, M0),
the configuration clock pin (CCLK), the PROGRAM pin, the
DONE pin and the boundary-scan pins (TDI, TDO, TMS,
TCK). Depending on the selected configuration mode,
CCLK may be an output generated by the FPGA, or may be
generated externally, and provided to the FPGA as an
input.
Note that some configuration pins can act as outputs. For
correct operation, these pins require a VCCO of 3.3V to drive
an LVTTL signal or 2.5V to drive an LVCMOS signal. All the
relevant pins fall in banks 2 or 3. The CS and WRITE pins
for Slave Parallel mode are located in bank 1.
For a more detailed description than that given below, see
"Pinout Tables" in Module 4 and XAPP176, Spartan-II
FPGA Series Configuration and Readback.
The Process
The sequence of steps necessary to configure Spartan-II
devices are shown in Figure 11. The overall flow can be
divided into three different phases.
Initiating Configuration
Configuration memory clear
Loading data frames
Start-up
The memory clearing and start-up phases are the same for
all configuration modes; however, the steps for the loading
of data frames are different. Thus, the details for data frame
loading are described separately in the sections devoted to
each mode.
Initiating Configuration
There are two different ways to initiate the configuration
process: applying power to the device or asserting the
PROGRAM input.
Configuration on power-up occurs automatically unless it is
delayed by the user, as described in a separate section
below. The waveform for configuration on power-up is
shown in Figure 12, page 19. Before configuration can
begin, VCCO Bank 2 must be greater than 1.0V.
Furthermore, all VCCINT power pins must be connected to a
2.5V supply. For more information on delaying
Once in user operation, the device can be re-configured
simply by pulling the PROGRAM pin Low. The device
acknowledges the beginning of the configuration process
by driving DONE Low, then enters the memory-clearing
phase.
