74 / 99 page ![]() Electrical characteristics STLUX385A 74/98 DocID024387 Rev 2 IC low power current consumption The following table summarizes the current consumption measured on V DD /V DDA supply pins in power saving conditions. I DD(WFI2) Flash HSE (5) 16 16 All 3.1 3.8 V DD /V DDA =3.3 V 3.8 5.6 V DD /V DDA =5 V 1. “All” means: I2C, UART, Dali, ITC, GPIO0, SysTimr, WWDG and IWDG peripherals active. 2. f MASTER clock source. 3. HSE frequency provided by external quartz. 4. The peripheral current consumption is supplied by the VCORE voltage (1.8 V). 5. Temperature operating: TA= 25 °C. 6. Data based on characterization results not tested in production. Table 37. Supply base current consumption at VDD/VDDA = 3.3/5 V (continued) Symbol Code Clock Peripheral Consumption(6) Note Table 38. Supply low power consumption at VDD/VDDA = 3.3/5 V Symbol Code Clock Peripheral Consumption(11) Note Op. mode (1)(2) Code area SRC (3) f MASTER f CPU E 2 PROM (6) MVRreg. (5) Typ. (8.10) Max.
