115 / 153 page  ST72334J/N, ST72314J/N, ST72124J 115/153 SUPPLY CURRENT CHARACTERISTICS (Cont’d) 16.4.3 HALT and ACTIVE-HALT Modes 16.4.4 Supply and Clock Managers The previous current consumption specified for the ST7 functional operating modes over tempera- ture range does not take into account the clock source current consumption. To get the total de- vice consumption, the two current values must be added (except for HALT mode). 16.4.5 On-Chip Peripherals Notes: 1. Typical data are based on TA=25°C. 2. All I/O pins in input mode with a static value at VDD or VSS (no load), CSS and LVD disabled. Data based on charac- terization results, tested in production at VDD max. and fCPU max. 3. Data based on design simulation and/or technology characteristics, not tested in production. All I/O pins in input mode with a static value at VDD or VSS (no load); clock input (OSC1) driven by external square wave, LVD disabled. 4. Data based on characterization results, not tested in production. 5. Data based on characterization results done with the external components specified in Section 16.5.3 and Section 16.5.4, not tested in production. 6. As the oscillator is based on a current source, the consumption does not depend on the voltage. 7. Data based on a differential IDD measurement between reset configuration (timer counter running at fCPU/4) and timer counter stopped (selecting external clock capability). Data valid for one timer. 8. Data based on a differential IDD measurement between reset configuration and a permanent SPI master communica- tion (data sent equal to 55h). 9. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
