NOTES:
1
Refer to Table 29 for additional PLL specifications.
2
Refer to the MCF5235 signals section for pins having weak internal pull-up devices.
3
This parameter is characterized before qualification rather than 100% tested.
4
pF load ratings are based on DC loading and are provided as an indication of driver strength. High speed interfaces
require transmission line analysis to determine proper drive strength and termination. See High Speed Signal
Propagation: Advanced Black Magic by Howard W. Johnson for design guidelines.
5
Current measured at maximum system clock frequency, all modules active, and default drive strength with matching
load.
6
All functional non-supply pins are internally clamped to V
SS
and their respective V
DD
.
7
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.
8
Power supply must maintain regulation within operating V
DD
range during instantaneous and operating maximum
current conditions. If positive injection current (V
in
> V
DD
) is greater than I
DD
, the injection current may flow out of V
DD
and could result in external power supply going out of regulation. Insure external V
DD
load will shunt current greater
than maximum injection current. This will be the greatest risk when the processor is not consuming power. Examples
are: if no system clock is present, or if clock rate is very low which would reduce overall power consumption. Also, at
power-up, system clock is not present during the power-up sequence until the PLL has attained lock.
