RAM Dynamic Contribution—PMEMORY
Operating Mode
PMEMORY = (NBLOCKS * PAC11 * 2 * FREAD-CLOCK) + (NBLOCKS * PAC12 * 3 * FWRITE-CLOCK)
NBLOCKS is the number of RAM blocks used in the design.
FREAD-CLOCK is the memory read clock frequency.
2 is the RAM enable rate for read operations—guidelines are provided in Table 3-17 on FWRITE-CLOCK is the memory write clock frequency.
Standby Mode and Sleep Mode
PMEMORY = 0 W
PLL/CCC Dynamic Contribution—PPLL
Operating Mode
PPLL = PAC13 * FCLKOUT
FCLKIN is the input clock frequency.
FCLKOUT is the output clock frequency.1
Standby Mode and Sleep Mode
PPLL = 0 W
Nonvolatile Memory Dynamic Contribution—PNVM
Operating Mode
The NVM dynamic power consumption is a piecewise linear function of frequency.
PNVM = NNVM-BLOCKS * 4 * PAC15 * FREAD-NVM when FREAD-NVM 33 MHz,
PNVM = NNVM-BLOCKS * 4 *(PAC16 + PAC17 * FREAD-NVM when FREAD-NVM > 33 MHz
NNVM-BLOCKS is the number of NVM blocks used in the design (2 inAFS600).
4 is the NVM enable rate for read operations. Default is 0 (NVM mainly in idle state).
Fis the NVM read clock frequency.
Standby Mode and Sleep Mode
PNVM = 0 W
Crystal Oscillator Dynamic Contribution—PXTL-OSC
Operating Mode
PXTL-OSC = PAC18
Standby Mode
PXTL-OSC = PAC18
Sleep Mode
PXTL-OSC = 0 W

The PLL dynamic contribution depends on the input clock frequency, the number of output clock signals generated by the
PLL, and the frequency of each output clock. If a PLL is used to generate more than one output clock, include each output
clock in the formula output clock by adding its corresponding contribution (PAC14 * FCLKOUT product) to the total PLL
contribution.
