ARM9 microcontroller with CAN and LIN
[1] Based on package heat transfer, not device power consumption.
[2] Peak current must be limited at 25 times average current.
[3] For I/O Port 0, the maximum input voltage is defined by V
I(ADC)
.
[4] Only when V
DD(IO)
is present.
[5] Note that pull-up should be off. With pull-up do not exceed 3.6 V.
[6] In accordance with IEC 60747-1. An alternative definition of the virtual junction temperature is: T
vj
=T

+P
tot
× R
th(j-a)
where R
th(j-a)
is
a fixed value; see Section 10
. The rating for T
vj
limits the allowable combinations of power dissipation and ambient temperature.
[7] Human-body model: discharging a 100 pF capacitor via a 10 kΩ series resistor.
[8] Machine model: discharging a 200 pF capacitor via a 0.75 μH series inductance and 10 Ω resistor.
[9] 112 mA per V
DD(IO)
or V
SS(IO)
should not be exceeded.
