Control, Clock, sysCONFIG and JTAG Signals
Global clock pins support the same sysIO standards as general purpose I/O. When required the VREF signal is
derived from the adjacent bank. When differential standards are supported two adjacent clock pins are paired to
form the input. The TOE, PROGRAM, CFG0 and DONE pins of the ispXPLD 5000MX device are the only pins that
do not have sysIO capabilities. The JTAG TAP pins support only LVCMOS 3.3, 2.5 and 1.8V standards. The voltage
is controlled by VCCJ. These pins only support the LVTTL and LVCMOS standards applicable to the power supply
voltage of the device. The global reset global output enable pins are associated with Bank 2 and support all of the
sysIO standards.
Hotsocketing
The I/O on the ispXPLD 5000MX devices are well suited for those applications that require hot socketing capability,
when configured as LVCMOS or LVTTL. Hot socketing a device requires that the device, when powered down, can
tolerate active signals on the I/Os and inputs without being damaged. Additionally, it requires that the effects of the
powered-down device be minimal on active signals.
Programmable Drive Strength
The drive strength of I/Os that are programmed as LVCMOS is tightly controlled and can be programmed to a vari-
ety of different values. Thus the impedance an output driver can be closely match to the characteristic impedance
of the line it is driving. This allows users to eliminate the need for external series termination resistors.
