5.3.4
Embedded reference voltage
The parameters given in Table 12 are derived from tests performed under ambient
temperature and VDD supply voltage conditions summarized in Table 9.
5.3.5
Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code.
The current consumption is measured as described in Figure 13: Current consumption
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to Dhrystone 2.1 code.
Maximum current consumption
The MCU is placed under the following conditions:
●
All I/O pins are in input mode with a static value at VDD or VSS (no load)
●
All peripherals are disabled except when explicitly mentioned
●
The Flash memory access time is adjusted to the fHCLK frequency (0 wait state from 0
to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states above)
●
Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)
●
When the peripherals are enabled fPCLK1 = fHCLK/2, fPCLK2 = fHCLK
The parameters given in Table 13, Table 14 and Table 15 are derived from tests performed
under ambient temperature and VDD supply voltage conditions summarized in Table 9.
