98 / 123 page  Electrical characteristics ST7FOXU0 98/123 12.4.2 On-chip peripherals 12.5 Clock and timing characteristics Subject to general operating conditions for VDD, fOSC, and TA. 12.5.1 Auto Wake Up from Halt oscillator (AWU) Table 46. On-chip peripheral characteristics Symbol Parameter Conditions Typ Unit IDD(AT) 12-bit Auto-Reload timer supply current(1) 1. Data based on a differential IDD measurement between reset configuration (timer stopped) and a timer running in PWM mode at fcpu= 8 MHz. fCPU=8 MHz VDD=5.0 V 30 µA IDD(ADC) ADC supply current when converting(2) 2. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions. fADC=4 MHz VDD=5.0 V 750 µA Table 47. General timings Symbol Parameter(1) 1. Guaranteed by Design. Not tested in production. Conditions Min Typ(2) 2. Data based on typical application software. Max Unit tc(INST) Instruction cycle time fCPU = 8 MHz 23 12 tCPU 250 375 1500 ns tv(IT) Interrupt reaction time(3) tv(IT) = ∆tc(INST) + 10 3.
