159 / 191 page  ST72340, ST72344, ST72345 159/191 13.6.2 On-chip peripherals Notes: 1. Data based on a differential IDD measurement between reset configuration (timer stopped) and a timer running in PWM mode at fcpu=8MHz. 2. Data based on a differential IDD measurement between reset configuration and a permanent SPI master communica- tion (data sent equal to 55h). 3. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions. 4. Data based on a differential IDD measurement between reset configuration (I2C disabled) and a permanent I2C master communication at 100kHz (data sent equal to 55h). This measurement include the pad toggling consumption (27kOhm external pull-up on clock and data lines). 5. Data based on a differential IDD measurement between SCI low power state (SCID=1) and a permanent SCI data trans- mit sequence. Symbol Parameter Conditions Typ Unit IDD(16-b timer) 16-bit Timer supply current 1) fCPU=4MHz VDD=3.0V 20 µA fCPU=8MHz VDD=5.0V 100 IDD(SPI) SPI supply current 2) fCPU=4MHz VDD=3.0V 250 fCPU=8MHz VDD=5.0V 800 IDD(ADC) ADC supply current when converting 3) fADC=2MHz VDD=3.0V 300 fADC=4MHz VDD=5.0V 1000 IDD(I2C) I2C supply current 4) fCPU=4MHz VDD=3.0V 100 fCPU=8MHz VDD=5.0V 500 IDD(SCI) SCI supply current 5) fCPU=4MHz VDD=3.0V 250 fCPU=8MHz VDD=5.0V 800 |
