111 / 145 page  ST7263BDx ST7263BHx ST7263BKx ST7263BE 111/145 14.4 Supply current characteristics The following 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 for which the clock is stopped). Notes: 1. Oscillator and watchdog running. All others peripherals disabled. 2. USB Transceiver and ADC are powered down. 3. Not tested in production, guaranteed by characterization. 4. CPU in Halt mode. Current consumption of external pull-up (1.5Kohms to USBVCC) and pull-down (15Kohms to VSSA) not included. Figure 52. Typ. IDD in Run at 4 and 8 MHz fCPU Figure 53. Typ.
