1. T
A
= -40 to 125 °C, no floating I/O, unless otherwise specified.
2. T
A
> 85 °C is valid only for devices with suffix 3 temperature range.
3. Tested in production.
4. ULP=0 or ULP=1 and FWU=1 in the PWR_CSR2 register.
5. Wakeup time until start of interrupt vector fetch.
The first word of interrupt routine is fetched 4 CPU cycles after t
