(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 configured as inputs; VIL = 0.2 V and VIH = VDD – 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) These currents are the summation of the MCU current + CAN current (IDD + IDD1).
Note:
The 4MHz bus frequency is achievable only in divide by 2 and divide by 4 modes. It is
not possible in divide by 10 mode.
