Parameter Interpretation
The parameters listed in the following include both the characteristics of the XC228xM
and its demands on the system. To aid in correctly interpreting the parameters when
evaluating them for a design, they are marked accordingly in the column “Symbol”:

1) Performance of pad drivers, A/D Converter, and Flash module depends on
V
DDP.
2) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin
exceeds the specified range:
VOV > VIHmax (IOV >0) or VOV < VILmin (IOV < 0). The absolute sum of input
overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the specified
limits. Proper operation under overload conditions depends on the application.
Overload conditions must not occur on pin XTAL1 (powered by
V
DDIM).
3) Not subject to production test - verified by design/characterization.
4) An overload current (
IOV) through a pin injects an error current (IINJ) into the adjacent pins. This error current
adds to that pin’s leakage current (
I
OZ). The value of the error current depends on the overload current and is
defined by the overload coupling factor
KOV. The polarity of the injected error current is reversed from the
polarity of the overload current that produces it.
The total current through a pin is |
ITOT| = |IOZ| + (|IOV| × KOV). The additional error current may distort the input
voltage on analog inputs.
5) This is the reference load. For bigger capacitive loads, use the derating factors from Section 4.6.4.
6) The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output
current may lead to increased delays or reduced driving capability (
C
L).
7) To ensure the stability of the voltage regulators the EVRs must be buffered with ceramic capacitors. Separate
buffer capacitors with the recomended values shall be connected as close as possible to each
VDDI pin to keep
the resistance of the board tracks below 2
Ω. Connect all V
DDI1 pins together.
The minimum capacitance value is required for proper operation under all conditions (e.g. temperature).
Higher values slightly increase the startup time.
8) The operating frequency range may be reduced for specific types of the
XC228xM. This is indicated in the
device designation (
…FxxL). 80-MHz devices are marked …F80L.
