Supply current in standby mode

TA = - 40°C

TA = 105°C

TA = 70°C

TA = 25°C

Figure 13. Typical current consumption in standby mode vs. temperature at VDD = 3.3V

Typical current consumption

The MCU is placed under the following conditions:

• All I/O pins are in analog input configuration, and are connected to a static level —- VDD

or VSS (no load).

• All the peripherals are closed, unless otherwise specified.

• The Flash memory access time is adjusted to the fHCLK (0

∼ 24 MHz is 0 waiting period

,24

∼ 48 MHzis 1 waiting period, 48 ∼ 72 MHzis 2 waiting period, 72 ∼ 96 MHzis 3

waiting period ).

• The ambient temperature and VDD supply voltage conditions are summarized in Ta-

ble 10.

• The instruction prefetching function is on. When the peripherals are enabled：

fPCLK1 = fHCLK.

Note: The instruction prefetch function must be set before the clock is set and the bus is divided.

On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 17. The MCU is

placed under the following conditions:

• All I/O pins are in analog input mode, and are connected to a static level —- VDD or VSS

(no load) .

• All peripherals are disabled except when explicitly mentioned.

• The given value is calculated by measuring the current consumption.

– with all peripherals clocked OFF

– with only one peripheral clocked on
