Maximum Tolerated Ratings

This section provides the maximum tolerated voltage and temperature ranges for the MPC852T. Table 1

provides the maximum ratings and operating temperatures.

Figure 2 shows the undershoot and overshoot voltages at the interface of the MPC852T.

1 The power supply of the device must start its ramp from 0.0 V.

VDDL (core voltage)

– 0.3 to 3.4

VDDH (I/O voltage)

– 0.3 to 4

VDDSYN

– 0.3 to 3.4

Input voltage2

2 Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum ratings are

stress ratings only; functional operation at the maxima is not guaranteed. Stresses beyond those listed may affect device

reliability or cause permanent damage to the device.

Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than VDDH. This restriction applies to power-up and

normal operation (that is, if the MPC852T is unpowered, a voltage greater than 2.5 V must not be applied to its inputs).
