also 1.5V I/O compatible with the use of Schmitt-trigger
inputs.
Another feature that eases voltage translation is I/O bank-
ing. Two I/O banks are available on the CoolRunner-II Auto-
motive 64-macrocell device that permit easy interfacing to
3.3V, 2.5V, 1.8V, and 1.5V devices.
RealDigital Design Technology
Xilinx CoolRunner-II Automotive CPLDs are fabricated on a
0.18 micron process technology which is derived from lead-
ing edge FPGA product development. CoolRunner-II Auto-
motive CPLDs employ RealDigital, a design technique that
makes use of CMOS technology in both the fabrication and
design methodology. RealDigital design technology
employs a cascade of CMOS gates to implement sum of
products instead of traditional sense amplifier methodology.
Due to this technology, Xilinx CoolRunner-II Automotive
CPLDs achieve both high performance and low power oper-
ation.
Supported I/O Standards
The CoolRunner-II Automotive 64-macrocell features both
LVCMOS and LVTTL I/O implementations. See Table 1 for
I/O standard voltages. The LVTTL I/O standard is a general
purpose EIA/JEDEC standard for 3.3V applications that use
an LVTTL input buffer and Push-Pull output buffer. The
LVCMOS standard is used in 3.3V, 2.5V, 1.8V applications.
CoolRunner-II Automotive CPLDs are also 1.5V I/O com-
patible with the use of Schmitt-trigger inputs.
