CoolRunner-II CPLD Family
Programming
The programming data sequence is delivered to the device
using either Xilinx iMPACT software and a Xilinx download
cable,
JTAG-compatible board tester, or a simple microprocessor
interface that emulates the JTAG instruction sequence. The
iMPACT software also outputs serial vector format (SVF)
files for use with any tools that accept SVF format, including
automatic test equipment. See
Application Notes
In System Programming
All CoolRunner-II CPLD parts are 1.8V in system program-
mable. This means they derive their programming voltage
and currents from the 1.8V V
pins on the part. The V

high as 3.3V down to 1.5V (however, all V

required to properly operate the internal state machines and
charge pumps that reside within the CPLD to do the nonvol-
atile programming operations. I/O pins are not in user mode
during JTAG programming; they are held in 3-state with a
weak pullup. The JTAG interface buffers are powered by a
dedicated power pin, V
other supply pins. V
ware is provided to deliver the bitstream to the CPLD and
drive the appropriate IEEE 1532 protocol. To that end, there
is a set of IEEE 1532 commands that are supported in the
CoolRunner-II CPLD parts. Programming times are less
than one second for 32 to 256 macrocell parts. Program-
ming times are less than four seconds for 384 and 512 mac-
rocell parts. Programming of CoolRunner-II CPLDs is only
guaranteed when operating in the commercial temperature
and voltage ranges as defined in the device-specific data
sheets.
On-The-Fly Reconfiguration (OTF)
The Xilinx ISE 5.2i tool supports OTF for CoolRunner-II
CPLDs. This permits programming a new nonvolatile pat-
tern into the part while another pattern is currently in use.
OTF has the same voltage and temperature specifications
as system programming. During pattern transition I/O pins
are in high impedance with a weak pullup to V
tion time typically lasts between 50 and 300 μs, depending
on density. See

Power-Up Characteristics
CoolRunner-II CPLD parts must operate under the
demands of both the high-speed and the portable market
places; therefore, they must support hot plugging for the
high-speed world and tolerate most any power sequence to
its various voltage pins. They must also not draw excessive
current during power-up initialization. To those ends, the
general behavior is summarized as follows:
1. I/O pins are disabled until the end of power-up.
2. As supply rises, configuration bits transfer from
3. As power up completes, the outputs become as
4. For specific configuration times and power up
CoolRunner-II CPLD I/O pins are well behaved under all
operating conditions. During power-up, CoolRunner-II
devices employ internal circuitry which keeps the devices in
the quiescent state until the V
safe level (approximately 1.3V). In the quiescent state,
JTAG pins are disabled, and all device outputs are disabled
with the pins weakly pulled High, as shown in

become initialized, and the device is immediately available
for operation, as shown in

If the device is in the erased state (before any user pattern
is programmed), the device outputs remain disabled with a
weak pull-up. The JTAG pins are enabled to allow the device
