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, not tested in production.

2. Data based on characterization results done with the external components specified in Section 12.5.3 , not tested in

production.

3. As the oscillator is based on a current source, the consumption does not depend on the voltage.

12.4.3 On-Chip Peripherals

TA = 25°C fCPU=4MHz.

Notes:

1. Data based on a differential IDD measurement between reset configuration (timer counter running at fCPU/4) and timer

counter stopped (only TIMD bit set). Data valid for one timer.

2. Data based on a differential IDD measurement between reset configuration (SPI disabled) and a permanent SPI master

communication at maximum speed (data sent equal to 55h). This measurement includes the pad toggling consump-

tion.

3. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
