ICC vs. FREQUENCY
These curves represent the typical power consumption for a particular device at system frequen-
cy.The selected “typical” pattern is a 16-bit up-down counter.This pattern fills the device and ex-
ercises 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 low-
est frequency signals (MSBs) are placed in a common PAL block and set to lowest power.
