1 This characteristic is for 2.6-V output and 5-V input friendly pins.
2 VDATAPC is the maximum voltage the data pins can have been precharged to by an external device when the
MPC561/MPC563 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 VDDL,
then the 50-pF 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 MPC561/MPC563 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 VDDL, then the maximum
load 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.
4 This characteristic is for 5-V output and 5-V input pins.
5 0.3V > V
DDA or VDDH, whichever is greater.
6 Within this range, no significant injection will be seen. See QADC64 Disruptive Input Current (I
NA).
7 During reset all 2.6V and 2.6V/5V pads will leak up to 10
A to QVDDL if the pad has a voltage > QVDDL.
8 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.
9 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 (or, optionally, 56-MHz) timing.
10 Only IRQ, TPU, MIOS, GPIO, QADC (when digital inputs) and RESET pins have hysteresis, thus there is no hysteresis
specification on all other pins
11 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.
12 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.
14 These power supplies are available on the MPC563 and MPC564 only.
15 Current measured at maximum system clock frequency with QADC active.
16 Transient currents can reach 50mA.
17 KAPWR and IRAMSTBY can be powered-up prior to any other supply or at the same time as the other 2.6 V supplies.
IRAMSTBY must lead or coincide with VDD; however it can lag KAPWR.
18 This parameter is periodically sampled rather than 100% tested
