Fast Zero Power Design Technology
Xilinx CoolRunner-II CPLDs are fabricated on a 0.18 micron
process technology which is derived from leading edge
FPGA product development. CoolRunner-II CPLDs employ
Fast Zero Power
(FZP), a design technique that makes
use of CMOS technology in both the fabrication and design
methodology. FZP design technology employs a cascade of
CMOS gates to implement sum of products instead of tradi-
tional sense amplifier methodology. Due to this technology,
Xilinx CoolRunner-II CPLDs achieve both high performance
and low power operation.
Supported I/O Standards
The CoolRunner-II 64 macrocell features both LVCMOS
and LVTTL I/O implementations. See
Table 1
for I/O stan-
dard voltages. The LVTTL I/O standard is a general purpose
EIA/JESDSA standard for 3.3V applications that use an
LVTTL input buffer and Push-Pull output buffer. The LVC-
MOS standard is used in 3.3V, 2.5V, 1.8V applications.
CoolRunner-II CPLDs are also 1.5V I/O compatible with the
use of Schmitt inputs.
