31.6.2 Temperature sensor/internal reference voltage characteristics
(T
A = −40 to +105°C, 2.4 V ≤ EVDD = VDD ≤ 5.5 V, VSS = EVSS = 0 V, HS (high-speed main) mode)
Parameter Symbol Conditions MIN. TYP. MAX. Unit
Temperature sensor output voltage VTMPS25 Setting ADS register = 80H, TA = +25°C 1.05 V
Internal reference voltage VBGR Setting ADS register = 81H 1.38 1.45 1.5 V

Operation stabilization wait time tAMP 5 μ s
31.6.3 POR circuit characteristics
(T
A = −40 to +105°C, VSS = 0 V)
Parameter Symbol Conditions MIN. TYP. MAX. Unit
Detection voltage VPOR Power supply rise time 1.45 1.51 1.57 V
VPDR Power supply fall time 1.44 1.50 1.56 V
Minimum pulse width TPW 300 μ s
Note Minimum time required for a POR reset when VDD exceeds below VPDR. This is also the minimum time required for a
POR reset from when VDD exceeds below 0.7 V to when VDD exceeds VPOR while STOP mode is entered or the main
system clock is stopped through setting bit 0 (HIOSTOP) and bit 7 (MSTOP) in the clock operation status control
register (CSC).
