Lattice Semiconductor
Typical Building Block Function Performance
Pin-to-Pin Performance (LVCMOS25 12mA Drive)
Register-to-Register Performance
Derating Logic Timing
Logic Timing provided in the following sections of the data sheet and the ispLEVER design tools are worst case
numbers in the operating range. Actual delays may be much faster. The ispLEVER design tool from Lattice can pro-
vide logic timing numbers at a particular temperature and voltage.
