These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified where these parameters may be affected.
ICC vs. FREQUENCY
These curves represent the typical power consumption for a particular device at system frequency. The
selected “typical” pattern is a 16-bit up-down counter. This pattern fills the device and exercises every
macrocell. Maximum frequency shown uses internal feedback and a D-type register. Power/Speed are
optimized to obtain the highest counter frequency and the lowest power. The highest frequency (LSBs) is
placed in common PAL blocks, which are set to high power. The lowest frequency signals (MSBs) are placed
in a common PAL block and set to lowest power. For a more detailed discussion about MACH 5 power
consumption, refer to the application note entitled MACH 5 Power in the Application Notes section on the
Lattice Data Book CD-ROM or Lattice web site.
