Test-System Reset Input
For normal system operation, pin TRST should be
held low. A high level at this pin at the rising edge
of PORST activates the XC2268I’s debug system.
In this case, pin TRST must be driven low once to
reset the debug system.
An internal pull-down device will hold this pin low
when nothing is driving it.

Functional Description
The architecture of the XC2268I combines advantages of RISC, CISC, and DSP
processors with an advanced peripheral subsystem in a well-balanced design. On-chip
memory blocks allow the design of compact systems-on-silicon with maximum
performance suited for computing, control, and communication.
The on-chip memory blocks (program code memory and SRAM, dual-port RAM, data
SRAM) and the generic peripherals are connected to the CPU by separate high-speed
buses. Another bus, the LXBus, connects additional on-chip resources and external
resources. This bus structure enhances overall system performance by enabling the
concurrent operation of several subsystems of the XC2268I.
The block diagram gives an overview of the on-chip components and the advanced
internal bus structure of the XC2268I.
3.1
Memory Subsystem and Organization
The memory space of the XC2268I is configured in the von Neumann architecture. In this
architecture all internal and external resources, including code memory, data memory,
registers and I/O ports, are organized in the same linear address space.

1) 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 VDDIM and VDDI1
pin to keep the resistance of the board tracks below 2 Ω. Connect all VDDI1 pins together. The minimum
capacitance value is required for proper operation under all conditions (e.g. temperature). Higher values
slightly increase the startup time.
2) Use one Capacitor for each pin.
3) This is the reference load. For bigger capacitive loads, use the derating factors listed in the PAD properties
section.
4) 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 (CL).
5) The operating frequency range may be reduced for specific device types. This is indicated in the device
designation (...FxxL). 80 MHz devices are marked ...F80L.
6) 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 VDDIM).
7) An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error
current adds to the respective pins leakage current (IOZ). The amount of error current depends on the overload
current and is defined by the overload coupling factor KOV. The polarity of the injected error current is inverse
compared to 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.
8) Value is controlled by on-chip regulator
9) To ensure a stable power up sequence, the external supply voltage must reach or exceed a level of 3.1 V
during power up for at least 0.5 ms.
For normal operation the complete specified voltage range is available.

Parameter Interpretation
The parameters listed in the following include both the characteristics of the XC2268I
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”:
CC (Controller Characteristics):
The logic of the XC2268I provides signals with the specified characteristics.
SR (System Requirement):
The external system must provide signals with the specified characteristics to the
XC2268I.

DC Parameters
These parameters are static or average values that may be exceeded during switching
transitions (e.g. output current).
Leakage current is strongly dependent on the operating temperature and the voltage
level at the respective pin. The maximum values in the following tables apply under worst
case conditions, i.e. maximum temperature and an input level equal to the supply
voltage.
The value for the leakage current in an application can be determined by using the
respective leakage derating formula (see tables) with values from that application.
The pads of the XC2268I are designed to operate in various driver modes. The DC
parameter specifications refer to the pad current limits specified in Section 4.6.4.
Supply Voltage Restrictions
The XC2268I can operate within a wide supply voltage range from 3.0 V to 5.5 V.
However, during operation this supply voltage must remain within 10 percent of the
selected nominal supply voltage. It cannot vary across the full operating voltage range.
Because of the supply voltage restriction and because electrical behavior depends on
the supply voltage, the parameters are specified separately for the upper and the lower
voltage range.
During operation, the supply voltages may only change with a maximum speed of
dV/dt < 1 V/ms.
During power-on sequences, the supply voltages may only change with a maximum
speed of dV/dt < 5 V/μs, i.e. the target supply voltage may be reached earliest after
approx. 1 μs.
Note: To limit the speed of supply voltage changes, the employment of external buffer
capacitors at pins VDDPA/VDDPB is recommended.

1) Because each double bond pin is connected to two pads (standard pad and high-speed pad), it has twice the
normal value. For a list of affected pins refer to the pin definitions table in chapter 2.
2) Not subject to production test - verified by design/characterization. Hysteresis is implemented to avoid
metastable states and switching due to internal ground bounce. It cannot suppress switching due to external
system noise under all conditions.
3) If the input voltage exceeds the respective supply voltage due to ground bouncing (VIN < VSS) or supply ripple
(VIN > VDDP), a certain amount of current may flow through the protection diodes. This current adds to the
leakage current. An additional error current (IINJ) will flow if an overload current flows through an adjacent pin.
Please refer to the definition of the overload coupling factor KOV.
4) The given values are worst-case values. In production test, this leakage current is only tested at 125 °C; other
values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating
depending on temperature (TJ = junction temperature [°C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [μA]. For example, at
a temperature of 95 °C the resulting leakage current is 3.2 μA. Leakage derating depending on voltage level
(DV = VDDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (μA]. This voltage derating formula is an approximation
which applies for maximum temperature.
5) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull
device: VPIN ≤ VILmax for a pullup; VPIN ≥ VIHmin for a pulldown.
6) These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in
general purpose IO pins.
7) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default
pin level: VPIN ≥ VIHmin for a pullup; VPIN ≤ VILmax for a pulldown.
8) The maximum deliverable output current of a port driver depends on the selected output driver mode. This
specification is not valid for outputs which are switched to open drain mode. In this case the respective output
will float and the voltage is determined by the external circuit.
9) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS,
VOH->VDDP). However, only the levels for nominal output currents are verified.

1) Because each double bond pin is connected to two pads (standard pad and high-speed pad), it has twice the
normal value. For a list of affected pins refer to the pin definitions table in chapter 2.
2) Not subject to production test - verified by design/characterization. Hysteresis is implemented to avoid
metastable states and switching due to internal ground bounce. It cannot suppress switching due to external
system noise under all conditions.
3) If the input voltage exceeds the respective supply voltage due to ground bouncing (VIN < VSS) or supply ripple
(VIN > VDDP), a certain amount of current may flow through the protection diodes. This current adds to the
leakage current. An additional error current (IINJ) will flow if an overload current flows through an adjacent pin.
Please refer to the definition of the overload coupling factor KOV.
4) The given values are worst-case values. In production test, this leakage current is only tested at 125 °C; other
values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating
depending on temperature (TJ = junction temperature [°C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [μA]. For example, at
a temperature of 95 °C the resulting leakage current is 3.2 μA. Leakage derating depending on voltage level
(DV = VDDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (μA]. This voltage derating formula is an approximation
which applies for maximum temperature.
5) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull
device: VPIN = VIH for a pulldown.
6) These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in
general purpose IO pins.
7) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default
pin level: VPIN >= VIH for a pullup; VPIN VSS,
VOH->VDDP). However, only the levels for nominal output currents are verified.
10) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS,
VOH->VDDP). However, only the levels for nominal output currents are verified.

Power Consumption
The power consumed by the XC2268I depends on several factors such as supply
voltage, operating frequency, active circuits, and operating temperature. The power
consumption specified here consists of two components:
•
•
The switching current IS depends on the device activity
The leakage current ILK depends on the device temperature
To determine the actual power consumption, always both components, switching current
IS and leakage current ILK must be added:
IDDP = IS + ILK.
Note: The power consumption values are not subject to production test. They are
verified by design/characterization.
To determine the total power consumption for dimensioning the external power
supply, also the pad driver currents must be considered.
The given power consumption parameters and their values refer to specific operating
conditions:
•
•
•
Active mode:
Regular operation, i.e. peripherals are active, code execution out of Flash.
Stopover mode:
Crystal oscillator and PLL stopped, Flash switched off, clock in domain DMP_1
stopped.
Standby mode:
Voltage domain DMP_1 switched off completely, power supply control switched off.
Voltage domain DMP_M is supplied by the ultra low power embedded voltage
regulator (ULPEVR). The standard regulator (EVR_M) is switched off.
Note: The maximum values cover the complete specified operating range of all
manufactured devices.
The typical values refer to average devices under typical conditions, such as
nominal supply voltage, room temperature, application-oriented activity.
After a power reset, the decoupling capacitors for VDDIM and VDDI1 are charged with
the maximum possible current.
For additional information, please refer to Section 5.2, Thermal Considerations.
Note: Operating Conditions apply.

2) The pad supply voltage pins (VDDPB) provide the input current for the on-chip EVVRs and the current
consumed by the pin output drivers. A small current is consumed because the drivers input stages are
switched.
In Fast Startup Mode (with the Flash modules deactivated), the typical current is reduced to 3 + 1.0 x fSYS.
3) Please consider the additional conditions described in section "Active Mode Power Supply Current".
4) These values are valid if the voltage validation circuits for VDDPB (SWD) and VDDIM (PVC_M) are off. Leaving
SWD and PVC_M active adds another 90 μA.
Active Mode Power Supply Current
The actual power supply current in active mode not only depends on the system
frequency but also on the configuration of the XC2268I’s subsystem.
Besides the power consumed by the device logic the power supply pins also provide the
current that flows through the pin output drivers.
A small current is consumed because the drivers’ input stages are switched.
The IO power domains can be supplied separately. Power domain A (VDDPA) supplies the
A/D converters and Port 6. Power domain B (VDDPB) supplies the on-chip EVVRs and all
other ports.
During operation domain A draws a maximum current of 1.5 mA for each active A/D
converter module from VDDPA.
In Fast Startup Mode (with the Flash modules deactivated), the typical current is reduced
to (3 + 1.0×fSYS) mA.

1) The supply current caused by leakage depends mainly on the junction temperature and the supply voltage.
The temperature difference between the junction temperature TJ and the ambient temperature TA must be
taken into account. As this fraction of the supply current does not depend on device activity, it must be added
to other power consumption values.
2) All inputs (including pins configured as inputs) are set at 0 V to 0.1 V or at VDDP - 0.1 V to VDDP and all outputs
(including pins configured as outputs) are disconnected.
Note: A fraction of the leakage current flows through domain DMP_A (pin VDDPA). This
current can be calculated as 7 000 × e-α, with α = 5 000 / (273 + 1.3×TJ).
For TJ = 150°C, this results in a current of 160 μA.
The leakage power consumption can be calculated according to the following formula:
ILK0 = 500 000 + e-α, with α = 3 000 / (273 + B×TJ) must be tagged “PWR_Management”

4) The broken wire detection delay against VAREF is measured in numbers of consecutive precharge cycles at a

frequency at the beginning of the respective timeframe. This parameter is useful to determine a time span for
re-triggering a LIN synchronization.
2) This parameter is tested for the fastest and the slowest selection. The medium selections are not subject to

Conditions for tSPO Timing Measurement
The time required for the transition from Power-On to Base mode is called tSPO. It is
measured under the following conditions:
Precondition: The pad supply is valid, i.e. VDDPB is above 3.0 V and remains above 3.0 V
even though the XC2268I is starting up. See also VDDPB requirements in Table 13.
Start condition: Power-on reset is removed (PORST = 1).
End condition: External pin toggle caused by first user instruction executed from FLASH

The data retention time of the XC2268I’s Flash memory (i.e. the time after which stored

5) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
few system clock cycles. This increases the stated durations noticably only at extremely low system clock
frequencies.
Access to the XC2268I Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
Flash access via the cacheable Flash address space requires one additional waitstate
in case of a cache miss, while the cache access (in case of a cache hit) requires no
waitstate at all.

Definition of Internal Timing
The internal operation of the XC2268I is controlled by the internal system clock fSYS.
Because the system clock signal fSYS can be generated from a number of internal and
external sources using different mechanisms, the duration of the system clock periods
(TCSs) and their variation (as well as the derived external timing) depend on the
mechanism used to generate fSYS. This must be considered when calculating the timing
for the XC2268I.

system clock (TCS).

XC2000 Family Derivatives / Premium Line
Electrical Parameters
Direct Drive
When direct drive operation is selected (SYSCON0.CLKSEL = 11B), the system clock is
derived directly from the input clock signal CLKIN1:
fSYS = fIN.
The frequency of fSYS is the same as the frequency of fIN. In this case the high and low
times of fSYS are determined by the duty cycle of the input clock fIN.
Selecting Bypass Operation from the XTAL11) input and using a divider factor of 1 results
in a similar configuration.
Prescaler Operation
When prescaler operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY =
1B), the system clock is derived either from the crystal oscillator (input clock signal
XTAL1) or from the internal clock source through the output prescaler K1 (= K1DIV+1):
fSYS = fOSC / K1.
If a divider factor of 1 is selected, the frequency of fSYS equals the frequency of fOSC. In
this case the high and low times of fSYS are determined by the duty cycle of the input
clock fOSC (external or internal).
The lowest system clock frequency results from selecting the maximum value for the
divider factor K1:
fSYS = fOSC / 1024.
4.6.2.1
Phase Locked Loop (PLL)
When PLL operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 0B),
the on-chip phase locked loop is enabled and provides the system clock. The PLL
multiplies the input frequency by the factor F (fSYS = fIN × F).
F is calculated from the input divider P (= PDIV+1), the multiplication factor N (=
NDIV+1), and the output divider K2 (= K2DIV+1):
(F = N / (P × K2)).
The input clock can be derived either from an external source at XTAL1 or from the onchip clock source.
The PLL circuit synchronizes the system clock to the input clock. This synchronization is
performed smoothly so that the system clock frequency does not change abruptly.
Adjustment to the input clock continuously changes the frequency of fSYS so that it is
locked to fIN. The slight variation causes a jitter of fSYS which in turn affects the duration
of individual TCSs.
1) Voltages on XTAL1 must comply to the core supply voltage VDDIM.

XC2268I
XC2000 Family Derivatives / Premium Line
Electrical Parameters
The timing in the AC Characteristics refers to TCSs. Timing must be calculated using the
minimum TCS possible under the given circumstances.
The actual minimum value for TCS depends on the jitter of the PLL. Because the PLL is
constantly adjusting its output frequency to correspond to the input frequency (from
crystal or oscillator), the accumulated jitter is limited. This means that the relative
deviation for periods of more than one TCS is lower than for a single TCS (see formulas
and Figure 17).
This is especially important for bus cycles using waitstates and for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter
is negligible.
The value of the accumulated PLL jitter depends on the number of consecutive VCO
output cycles within the respective timeframe. The VCO output clock is divided by the
output prescaler K2 to generate the system clock signal fSYS. The number of VCO cycles
is K2 × T, where T is the number of consecutive fSYS cycles (TCS).
The maximum accumulated jitter (long-term jitter) DTmax is defined by:
DTmax [ns] = ±(220 / (K2 × fSYS) + 4.3)
This maximum value is applicable, if either the number of clock cycles T > (fSYS / 1.2) or
the prescaler value K2 > 17.
In all other cases for a timeframe of T × TCS the accumulated jitter DT is determined by:
DT [ns] = DTmax × [(1 - 0.058 × K2) × (T - 1) / (0.83 × fSYS - 1) + 0.058 × K2]
fSYS in [MHz] in all formulas.
Example, for a period of 3 TCSs @ 33 MHz and K2 = 4:
Dmax = ±(220 / (4 × 33) + 4.3) = 5.97 ns (Not applicable directly in this case!)
D3 = 5.97 × [(1 - 0.058 × 4) × (3 - 1) / (0.83 × 33 - 1) + 0.058 × 4]
= 5.97 × [0.768 × 2 / 26.39 + 0.232]
= 1.7 ns
Example, for a period of 3 TCSs @ 33 MHz and K2 = 2:
Dmax = ±(220 / (2 × 33) + 4.3) = 7.63 ns (Not applicable directly in this case!)
D3 = 7.63 × [(1 - 0.058 × 2) × (3 - 1) / (0.83 × 33 - 1) + 0.058 × 2]
= 7.63 × [0.884 × 2 / 26.39 + 0.116]

Wakeup Clock
When wakeup operation is selected (SYSCON0.CLKSEL = 00B), the system clock is
derived from the low-frequency wakeup clock source:
fSYS = fWU.
In this mode, a basic functionality can be maintained without requiring an external clock
source and while minimizing the power consumption.
4.6.2.3
Selecting and Changing the Operating Frequency
When selecting a clock source and the clock generation method, the required
parameters must be carefully written to the respective bitfields, to avoid unintended
intermediate states.
Many applications change the frequency of the system clock (fSYS) during operation in
order to optimize system performance and power consumption. Changing the operating
frequency also changes the switching currents, which influences the power supply.
To ensure proper operation of the on-chip EVRs while they generate the core voltage,
the operating frequency shall only be changed in certain steps. This prevents overshoots
and undershoots of the supply voltage.
To avoid the indicated problems, recommended sequences are provided which ensure
the intended operation of the clock system interacting with the power system.

External Clock Input Parameters
These parameters specify the external clock generation for the XC2268I. The clock can
be generated in two ways:
•
•
By connecting a crystal or ceramic resonator to pins XTAL1/XTAL2
By supplying an external clock signal
– This clock signal can be supplied either to pin XTAL1 (core voltage domain) or to
pin CLKIN1 (IO voltage domain)
If connected to CLKIN1, the input signal must reach the defined input levels VIL and VIH.
If connected to XTAL1, a minimum amplitude VAX1 (peak-to-peak voltage) is sufficient for
the operation of the on-chip oscillator.
Note: The given clock timing parameters (t1 … t4) are only valid for an external clock
input signal.

1) For frequencies above 16 MHz, it is mandatory to measure the oscillation allowance. Please refer to the
general note below.
2) The amplitude voltage VAX1 refers to the offset voltage VOFF. This offset voltage must be stable during the
operation and the resulting voltage peaks must remain within the limits defined by VIX1.
3) Overload conditions must not occur on pin XTAL1.
Note: For crystal or ceramic resonator operation, it is strongly recommended to measure
the oscillation allowance (negative resistance) in the final target system (layout) to
determine the optimum parameters for oscillator operation.
The manufacturers of crystals and ceramic resonators offer an oscillator
evaluation service. This evaluation checks the crystal/resonator specification

Pad Properties
The output pad drivers of the XC2268I can operate in several user-selectable modes.
Strong driver mode allows controlling external components requiring higher currents
such as power bridges or LEDs. Reducing the driving power of an output pad reduces
electromagnetic emissions (EME). In strong driver mode, selecting a slower edge
reduces EME.
The dynamic behavior, i.e. the rise time and fall time, depends on the applied external
capacitance that must be charged and discharged. Timing values are given for a
capacitance of 20 pF, unless otherwise noted.
In general, the performance of a pad driver depends on the available supply voltage
VDDP. Therefore the following tables list the pad parameters for the upper voltage range
and the lower voltage range, respectively.
Note: These parameters are not subject to production test but verified by design and/or

Note: These parameters are not subject to production test but verified by design and/or

Bus Interface Performance Limits
The output frequency at the bus interface pins is limited by the performance of the output
drivers. The fast clock driver (used for CLKOUT) can drive 80-MHz signals, the standard
drivers can drive 40-MHz signals
Therefore, the speed of the EBC must be limited, either by limiting the system frequency
to fSYS ≤ 80 MHz or by adding waitstates so that signal transitions have a minimum
distance of 12.5 ns.

The duration of the access phase can optionally be controlled by the external module

Note: The bandwidth of a parameter (from minimum to maximum value) covers the
whole operating range (temperature, voltage) as well as process variations. Within
a given device, however, this bandwidth is smaller than the specified range. This
is also due to interdependencies between certain parameters. Some of these
interdependencies are described in additional notes (see standard timing).

Bus Cycle Control with the READY Input
The duration of an external bus cycle can be controlled by the external circuit using the
READY input signal. The polarity of this input signal can be selected.
Synchronous READY permits the shortest possible bus cycle but requires the input
signal to be synchronous to the reference signal CLKOUT.
An asynchronous READY signal puts no timing constraints on the input signal but incurs
a minimum of one waitstate due to the additional synchronization stage. The minimum
duration of an asynchronous READY signal for safe synchronization is one CLKOUT
period plus the input setup time.
An active READY signal can be deactivated in response to the trailing (rising) edge of
the corresponding command (RD or WR).
If the next bus cycle is controlled by READY, an active READY signal must be disabled
before the first valid sample point in the next bus cycle. This sample point depends on
the programmed phases of the next cycle.

1) Device mounted on a 4-layer JEDEC board (according to JESD 51-7) with thermal vias; exposed pad soldered
to the board.
Using this device without the exposed pad soldered or on boards without thermal vias is not recommended.
Note: To improve the EMC behavior, it is recommended to connect the exposed pad to
the board ground, independent of the thermal requirements.
Board layout examples are given in an application note.
Usage in High-Performance Applications
The XC2268I can deliver a high performance to the system. In some cases additional
measures are required to remove the heat from the device.
This may be necessary if the XC2268I is supplied with VDDP = 5 V and is operated at a
high system frequency in a hot environment.
Applications with VDDP = 3.3 V usually require no extra measures.
Package Compatibility Considerations
The XC2268I is a member of the XC2000 Family of microcontrollers. It is also compatible
to a certain extent with members of similar families or subfamilies.
Each package is optimized for the device it houses. Therefore, there may be slight
differences between packages of the same pin-count but for different device types. In
particular, the size of the Exposed Pad (if present) may vary.
If different device types are considered or planned for an application, it must be ensured
that the board layout fits all packages under consideration.

Thermal Considerations
When operating the XC2268I in a system, the total heat generated in the chip must be
dissipated to the ambient environment to prevent overheating and the resulting thermal
damage.
The maximum heat that can be dissipated depends on the package and its integration
into the target board. The “Thermal resistance RΘJA” quantifies these parameters. The
power dissipation must be limited so that the average junction temperature does not
exceed 150 °C.
The difference between junction temperature and ambient temperature is determined by
ΔT = (PINT + PIOSTAT + PIODYN) × RΘJA
The internal power consumption is defined as
PINT = VDDP × IDDP (switching current and leakage current).
The static external power consumption caused by the output drivers is defined as
PIOSTAT = Σ((VDDP-VOH) × IOH) + Σ(VOL × IOL)
The dynamic external power consumption caused by the output drivers (PIODYN) depends
on the capacitive load connected to the respective pins and their switching frequencies.
If the total power dissipation for a given system configuration exceeds the defined limit,
countermeasures must be taken to ensure proper system operation:
•
•
•
•
Reduce VDDP, if possible in the system
Reduce the system frequency
Reduce the number of output pins
Reduce the load on active output drivers
