MPC866/859 Hardware Speciﬁcations

MOTOROLA

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.

DC Characteristics

Table 6 shows the DC electrical characteristics for the MPC866/859.

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.
