1.VDD = 5.0 Vdc ± 0.5v, VSS = 0 Vdc, TA = –40 °C to TA (MAX), unless otherwise noted.
2.Run (Operating) IDD measured using external square wave clock source (fBUS = 8.4 MHz). All inputs 0.2 V from rail.
No dc loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capaci-
tance linearly affects run IDD. Measured with all modules enabled.
3.Wait IDD measured using external square wave clock source (fBUS = 8.4 MHz). All inputs 0.2 Vdc from rail. No dc
loads. Less than 100 pF on all outputs, CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance
linearly affects wait IDD. Measured with all modules enabled.
4.Stop IDD measured with OSC1 = VSS.
5.Maximum is highest voltage that POR is guaranteed.
6.Maximum is highest voltage that POR is possible.
7.If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until
minimum VDD is reached.
8.See Computer Operating Properly (COP) on page 167. VHI applied to RST.
9.Although IDD is proportional to bus frequency, a current of several mA is present even at very low frequencies.
10.See monitor mode description within Computer Operating Properly (COP) on page 167. VHI applied to IRQ or RST.
11.When subjected to a Human Body Model (HBM) ESD event as specified in AEC Q100-002 these pins may exhibit recov-
erable leakage values within the specification indicated.

1.VDD = 5.0 Vdc ± 0.5v, VSS = 0 Vdc, TA = –40 °C to TA (MAX), unless otherwise noted.
2.Refer to Table 17-2 and Table 22-2 and supporting notes.
3.The minimum period tTLTL or tILIL should not be less than the number of cycles it takes to execute the capture interrupt
service routine plus tcyc.
4. The minimum pulse width to wake up the MSCAN module is guaranteed by design but not tested.
