145 / 189 page  ST72321 145/189 SUPPLY CURRENT CHARACTERISTICS (Cont’d) 12.4.2 Supply and Clock Managers The previous current consumption specified for the ST7 functional operating modes over temperature range does not take into account the clock source current consumption. To get the total device consump- tion, the two current values must be added (except for HALT mode). Notes: 1.. Data based on characterization results done with the external components specified in Section 12.5.3, not tested in production. 2. As the oscillator is based on a current source, the consumption does not depend on the voltage. Symbol Parameter Conditions Typ Max Unit IDD(RCINT) Supply current of internal RC oscillator 625 µA IDD(RES) Supply current of resonator oscillator 1) & 2) see section 12.5.3 on page 148 IDD(PLL) PLL supply current VDD= 5V 360 IDD(LVD) LVD supply current VDD= 5V 150 300 |
