(1) All IDD measurements taken with suitable decoupling capacitors across the power supply to suppress the transient
switching currents inherent in CMOS designs (see Section 2).
(2) Typical values are at mid point of voltage range and at 25°C only.
(3) RUN and WAIT IDD: measured using an external square-wave clock source, refer to Figure 2-6(c); all inputs 0.2 V
from rail; no DC loads; maximum load on outputs 50pF (20pF on OSC2).
STOP/WAIT IDD: all ports conï¬gured as inputs; VIL = 0.2 V and VIH = VDD â 0.2 V: STOP IDD measured with
OSC1 = VDD. WAIT IDD is affected linearly by the OSC2 capacitance.
(4) fOSC = 8 MHz; fBUS = 4 MHz; fCAN = 4 MHz
(5) fOSC = 4.4 MHz; fBUS = 2.2 MHz; fCAN = 2.2 MHz
(6) These limits are also applicable under the following conditions:
MCU RUN mode/SLOW mode/CAN active
MCU WAIT mode/SLOW mode/CAN active
MCU WAIT mode/CAN active
(7) These limits are also applicable under the following conditions:
MCU WAIT mode/SLOW mode/CAN asleep
(8) These currents are the summation of the MCU current + CAN current (IDD + IDD1)
(9) Current injection is guaranteed but not tested.
Functionality of the MCU is guaranteed during injection of dc current up to the maximum speciï¬ed level.
The maximum speciï¬ed current for each port is the sum of the magnitudes of the currents on each side of the
individual port pins.
Some disturbance of the A/D accuracy is possible during an injection event and is dependent on board layout,
power supply decoupling and reference voltage decoupling conï¬gurations.
