ARM9 microcontroller with CAN and LIN
[1] All parameters are guaranteed over the virtual junction temperature range by design. Pre-testing is performed at T
amb
= 125 °C on wafer
level. Cased products are tested at T
amb
=25°C (final testing). Both pre-testing and final testing use correlated test conditions to cover
the specified temperature and power-supply voltage range.
[2] Leakage current is exponential to temperature; worst-case value is at 125 °C T
vj
. All clocks off. Analog modules and flash powered
down.
[3] For Port 0, pin 0 to pin 15 add maximum 1.5 pF for input capacitance to ADC. For Port 0, pin 16 to pin 31 add maximum 1.0 pF for input
capacitance to ADC.
[4] This value is the minimum drive capability. Maximum short-circuit output current is 33 mA (drive HIGH-level, shorted to ground) or
−38 mA. (drive LOW-level, shorted to V
DD(IO)
). The device will be damaged if multiple outputs are shorted.
[5] C
xtal
is crystal load capacitance and C
ext
are the two external load capacitors.
[6] The power-up reset has a time filter: V
DD(CORE)
must be above V
trip(high)
for 2 µs before reset is de-asserted; V
DD(CORE)
must be below
V
trip(low)
for 11 µs before internal reset is asserted.
[7] Not 5 V-tolerant when pull-up is on.
[8] For I/O Port 0, the maximum input voltage is defined by V
I(ADC)
.
[9] This parameter is not part of production testing or final testing, hence only a typical value is stated. Maximum and minimum values are
based on simulation results.
