85 / 138 page ![]() MPC5644A Microcontroller Data Sheet, Rev. 7 Freescale Semiconductor 85 3.9 I/O pad current specifications The power consumption of an I/O segment depends on the usage of the pins on a particular segment. The power consumption is the sum of all output pin currents for a particular segment. The output pin current can be calculated from Table 22 based on the voltage, frequency, and load on the pin. Use linear scaling to calculate pin currents for voltage, frequency, and load parameters that fall outside the values given in Table 22. Table 22. I/O pad average IDDE specifications1 1 Numbers from simulations at best case process, 150 °C. Pad Type Symbol C Period (ns) Load2 (pF) 2 All loads are lumped.
