3.8.1
I/O Pad Current Specifications
The power consumption of an I/O segment depends on the usage of the pins on a particular segment. The
power consumption is the sum of all output pin currents for a particular segment. The output pin current
can be calculated from
Table 10
based on the voltage, frequency, and load on the pin. Use linear scaling to
calculate pin currents for voltage, frequency, and load parameters that fall outside the values given in
Table 10
.
7
High use current measured while running optimized SPE assembly code with all code and data 100% locked in cache (0%
miss rate) with all channels of the eMIOS and eTPU running autonomously, plus the eDMA transferring data continuously from
SRAM to SRAM. Higher currents could be seen if an “idle” loop that crosses cache lines is run from cache. Code should be
written to avoid this condition.
8
Preliminary. Final specification pending characterization.
9
Power requirements for the VDD33 supply are dependent on the frequency of operation and load of all I/O pins, and the
voltages on the I/O segments. See
Table 11
for values to calculate power dissipation for specific operation.
10
Power requirements for each I/O segment are dependent on the frequency of operation and load of the I/O pins on a particular
I/O segment, and the voltage of the I/O segment. See
Table 10
for values to calculate power dissipation for specific operation.
The total power consumption of an I/O segment is the sum of the individual power consumptions for each pin on the segment.

Weak pull up/down inactive. Measured at VDDE = 3.6 V and VDDEH = 5.25 V. Applies to pad types: pad_fc, pad_sh, and
pad_mh.
14
Maximum leakage occurs at maximum operating temperature. Leakage current decreases by approximately one-half for each
8 to 12
o
C, in the ambient temperature range of 50 to 125
o
C. Applies to pad types: pad_a and pad_ae.
15
VSSA refers to both VSSA0 and VSSA1. | VSSA0–VSSA1 | must be < 0.1V
16
Up to 0.6 volts during power up and power down.
