A.3 Supply Currents
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
A.3.1 Measurement Conditions
Run current is measured on the VDDX, VDDR
1
, and VDDA
2
pins. It does not include the current to drive
external loads. Unless otherwise noted the currents are measured in special single chip mode and the CPU
code is executed from RAM. For Run and Wait current measurements PLL is on and the reference clock
is the IRC1M trimmed to 1MHz. The bus frequency is 25MHz and the CPU frequency is 50MHz.
Table A-12., Table A-13. and Table A-14. show the configuration of the CPMU module and the
peripherals for Run, Wait and Stop current measurement.
Table A-11. Pin Interrupt Characteristics (Junction Temperature From +150C To +160C)
Conditions are 3.13V < V
DD35
< 5.5 V unless otherwise noted.

1. On some packages VDDR is bonded to VDDX and the pin is named
VDDXR. Refer to Section 1.8, “Device Pinouts” for further details.
2. On some packages VDDA is connected with VDDXR and the common pin
is named VDDXRA.On some packages VSSA is connected to VSSX and the common pin is named
VSSXA. See section Section 1.8, “Device Pinouts” for further details.
