dependent functionalities (from Run/active down to standby).
Updated I
DD
(Supply current during wakeup time from Standby
mode) in Table 23: Typical and maximum current consumptions in
Standby mode
The comment "HSE = 16 MHz(2) (PLL ON for fHCLK above 16
MHz)" replaced by "fHSE = fHCLK up to 16 MHz included, fHSE =
fHCLK/2 above 16 MHz (PLL ON)(2)” in Table 19: Current
consumption in Sleep mode
Updated Stop mode current to
1.2 µA in Ultra-low-power platform
Updated entire Section 7: Package characteristics
Removed alternate function “I2C2_SMBA” for GPIO pin “PH2” in
Table 8: STM32L15xxx pin definitions
Updated Table 27: Typical connection diagram using the ADC and
definition of symbol “R
AIN
” in Table 54: ADC characteristics
Removed first sentence in I2C interface characteristics
