10 / 92 page ![]() 10 MPC866/859 Hardware Specifications MOTOROLA Power Dissipation Power Dissipation 5 Power Dissipation Table 5 shows power dissipation information. The modes are 1:1, where CPU and bus speeds are equal, and 2:1 mode, where CPU frequency is twice the bus speed. 6 DC Characteristics Table 6 shows the DC electrical characteristics for the MPC866/859. Table 5. Power Dissipation (PD) Die Revision Bus Mode CPU Frequency Typical 1 1 Typical power dissipation at VDDL and VDDSYN is at 1.8 V. and VDDH is at 3.3 V. Maximum 2 2 Maximum power dissipation at VDDL and VDDSYN is at 1.9 V, and VDDH is at 3.465 V. NOTE Values in Table 5 represent VDDL based power dissipation and do not include I/O power dissipation over VDDH. I/O power dissipation varies widely by application due to buffer current, depending on external circuitry. The VDDSYN power dissipation is negligible.
