Design Security
XC9500XV devices incorporate advanced data security fea-
tures which fully protect the programming data against
unauthorized reading or inadvertent device erasure/repro-
gramming.
available.
The read security bits can be set by the user to prevent the
internal programming pattern from being read or copied.
When set, they also inhibit further program operations but
allow device erase. Erasing the entire device is the only way
to reset the read security bit.
The write security bits provide added protection against
accidental device erasure or reprogramming when the
JTAG pins are subject to noise, such as during system
power-up. Once set, the write-protection may be deacti-
vated when the device needs to be reprogrammed with a
valid pattern with a specific sequence of JTAG instructions

Low Power Mode
All XC9500XV devices offer a low-power mode for individ-
ual macrocells or across all macrocells. This feature allows
the device power to be significantly reduced.
Each individual macrocell may be programmed in
low-power mode by the user. Performance-critical parts of
the application can remain in standard power mode, while
other parts of the application may be programmed for
low-power operation to reduce the overall power dissipa-
tion. Macrocells programmed for low-power mode incur
additional delay (T
well as register setup time. Product term clock to output and
product term output enable delays are unaffected by the
macrocell power-setting.
Timing Model
The uniformity of the XC9500XV architecture allows a sim-
plified timing model for the entire device. The basic timing
model, shown in
that use the direct product terms only, with standard power
setting, and standard slew rate setting.
each of the key timing parameters is affected by the product
term allocator (if needed), low-power setting, and slew-lim-
ited setting.
The product term allocation time depends on the logic span
of the macrocell function, which is defined as one less than
the maximum number of allocators in the product term path.
If only direct product terms are used, then the logic span is
"0". The example in
terms are available with a span of "1". In the case of
