Electrical Parameters
Table 16 shows the maximum active current within the device in the reduced voltage
condition of 2.5 V < VDDP < 3.0 V. The active current consumption needs to be below the
specified values as according to the VDDP voltage. If the conditions are not met, a
brownout reset may be triggered.

Table 17 provides the active current consumption of some modules operating at 8 MHz
active mode, 3 V power supply at 25° C. The typical values shown are used as a
reference guide for device operating in reduced voltage conditions.

1) Modules that are controllable by programming the register PMCON1.
2) Not subject to production test, verified by design/characterisation.
3) Baseload current is measured when the device is running in user mode with an endless loop in the flash
memory. All modules in register PMCON1 are disabled.
4) ADC active current is measured with: module enable, ADC analog clock at 8MHz, running in parallel
conversion request in autoscan mode for 4 channels
5) SSC active curremt is measured with: module enabled, running in loop back mode at a baud rate of 1 MBaud
6) CCU6 active current is measured with: module enabled, all timers running in 8 MHz, 6 PWM outputs are
generated.
