XC2C64 CoolRunner-II CPLD
Supported I/O Standards
The CoolRunner-II 64 macrocell features both LVCMOS
and LVTTL I/O implementations. See
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, and 1.5V applica-
tions. It does not require the use of a reference voltage or
termination voltage.
