This characteristic is for 2.6-V output and 5-V input friendly pins.

VDATAPC is the maximum voltage the data pins can have been precharged to by an external device when the MPC533
data pins turn on as outputs. The 3.1-V maximum for VDATAPC is to allow the data pins to be driven from an external
memory running at a higher voltage. Note that if the data pins are precharged to higher than V
maximum load characteristic must be observed.
3
The predischarge circuit is enabled by setting the PREDIS_EN bit to a "1" in the PDMCR2 register. VDATAPC is the
maximum voltage the data pins can have been precharged to by an external device when the MPC533 data pins turn
on as outputs. The 5.25-V maximum for VDATAPC is to allow the data pins to be driven from an external memory
running at a higher voltage. Note that if the data pins are precharged to higher than V
characteristic must match the data bus drive setting and the data bus can withstand up to 3.6 volts for a cumulative
time of 24 hours over the lifetime of the device.

This characteristic is for 5-V output and 5-V input pins.

Within this range, no significant injection will be seen. See QADC64 Disruptive Input Current (I
7
Maximum leakage occurs at maximum operating temperature. Current decreases by approximately one-half for each
8 to 12 °C, in the ambient temperature range of 50 to 125 °C.
8
All bus pins support two drive strengths capabilities, 25 pF and 50 pF. Current drive is less at the 25-pF
capacitive load. Both modes achieve 40-MHz timing.
9
Only IRQ, MIOS, GPIO, QADC (when digital inputs) and RESET pins have hysteresis, thus there is no hysteresis
specification on all other pins
10
Values to be characterized. Current consumption values will be updated as information becomes available. Initial
values are only estimates based on predicted capacitive differences between CDR1 and CDR3 as well as actual CDR1
measurements.
11
All power consumption specifications assume 50-pF loads and running a typical application. The power consumption
of some modules could go up if they are exercised heavier, but the power consumption of other modules would
decrease.
12
Current measured at maximum system clock frequency with QADC active.
13
Transient currents can reach 50mA.

KAPWR and can be powered-up prior to any other supply or at the same time as the other 2.6 V supplies.

When using the QADC in legacy mode it is recommended to connect this pin to 2.6V or 3.3V, however it can be
connected to 0V or 5V without damage to the device.
19
All injection current is transferred to the V
power supply within the specified voltage range.
20
Total injection current for all I/O pins on the chip must not exceed 20 mA (sustained current). Exceeding this limit can
cause disruption of normal operation.
21
Current refers to two QADC64 modules operating simultaneously.
22
Below disruptive current conditions, the channel being stressed has conversion values of 0x3FF for analog inputs
greater than V and 0x000 for values less than V
