Power Estimation Equations
ICC = ICC_DC + IMFB_CPLD + IMFB_ SRAM/PDPRAM/FIFO + IMFB_DPRAM + IMFB_CAM + IPLL_D
ICC_DC
Use the appropriate value for 5000MC (1.8V power supply) or 5000MV/B (2.5V/3.3V power supply) from the data
sheet.
IMFB_CPLD
= ((K0 * CPLD MFB inputs + K1 * CPLD Logical Product Terms + K2 * CPLD GRP from MFB + K3 * CPLD GRP
from IFB) * AF+ K4) * FREQ / 1000A/mA
IMFB_CAM
= CAM Memory MFBs * ((FREQ * K8) + K9) (CAM operating in typical mode)
IMFB_ SRAM/PDPRAM/FIFO
= (WR_ PERCENT * (K1 + WR_ PERCENT * 8 * K0 + K10 + K11) + RD_ PERCENT * (K1 + 128 * RD_PERCENT
* K0 + 8 * OSW_PERCENT * K2)) * SRAM/PDPRAM/FIFO Memory MFBs * FREQ / 1000A/mA
IMFB_ DPRAM
= (WR_ PERCENT * (2 * K1 + 2 * WR_ PERCENT * 8 * K0 + K10 + K11) + RD_ PERCENT * (2 * K1 + 2 * 128 *
RD_PERCENT * K0 + 8 * OSW_PERCENT * K2)) * DPRAM Memory MFBs * FREQ / 1000A/mA
IPLL_D
= K5 * PLL_FREQ * number of PLLs used. IPPL_D is the PLL digital component of the VCC supply current.
Analog portion of PLL supply current consumption, from PLL power pin:
IPLL_A = (K6 * PLL_FREQ + K7) * number of PLLs used
Notes:
ICC = Current consumption of VCC power supply (mA)
ICC-DC = ICC DC component – Current consumption at 0Mhz (mA)
IMFB_CPLD = CPLD (non-memory logic) current consumption (mA)
IMFB_SRAM/PDPRAM/FIFO = Current consumption for SRAM, PDPRAM, and FIFO (mA)
IMFB_DPRAM = Current consumption for DPRAM (mA)
IMFB_CAM = Current consumption for CAM (mA)
IPLL_D = PLL Current consumption of digital VCC power supply (mA)
IPLL_A = PLL analog power pin current consumption (VCCP pin)
