Freescale Semiconductor

DC Characteristics

Table5 provides the DC electrical characteristics for the MPC852T.

Maximum power dissipation at VDDL and VDDSYN is at 1.9 V. and VDDH is at 3.465 V.

NOTE

Values in Table 4 represent VDDL-based power

dissipation, and do not include I/O power dissipation

over VDDH. I/O power dissipation varies widely by

application that buffer current can cause, depending

on external circuitry.

The VDDSYN power dissipation is negligible.
