(1)IDDIO current is dependent on the electrical loading on the I/O pins.

(2)The IDD3VFL current indicated in this table is the flash read-current and does not include additional current for erase/write operations. During flash programming, extra current is drawn from the VDD and VDD3VFL rails, as indicated in Table 6-45 . If the user application involves on-board flash programming, this extra current must be taken into account while architecting the power-supply stage.

(3)IDDA18 includes current into VDD1A18 and VDD2A18 pins. In order to realize the IDDA18 currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.

(4)IDDA33 includes current into VDDA2 and VDDAIO pins.

(5)TYP numbers are applicable over room temperature and nominal voltage.

(6)MAX numbers are at 125°C and MAX voltage.

NOTE

The peripheral - I/O multiplexing implemented in the 280x devices prevents all available peripherals from being used at the same time. This is because more than one peripheral function may share an I/O pin. It is, however, possible to turn on the clocks to all the peripherals at the same time, although such a configuration is not useful. If this is done, the current drawn by the device will be more than the numbers specified in the current consumption tables.
