Note 1: Specifications to -40°C are guaranteed by design and are not production tested.
Note 2: Typical value presented for reference only. Do not draw current from this pin.
Note 3: FLL disabled. Crystal connected across HFXIN and HFXOUT. Operating in divide-by-1 mode. Measured on the DVDD pin
and part executing program code from flash. All inputs are connected to GND or DVDD. Outputs do not source/sink any
current. Timer B enabled.
Note 4: This parameter is guaranteed by design and is not production tested.
Note 5: FLL enabled. f
32KIN
= 32.768kHz, HFXIN = disconnected, FLL = 8.39MHz, measured on the DVDD pin, part executing
program code from flash. All inputs are connected to GND or DVDD. Outputs do not source/sink any current. Timer B
enabled.
Note 6: I
STOP
is the total current into the device when the device is in stop mode. This includes both the digital and analog current
(current into DVDD and AVDD).
Note 7: Regulator, brownout monitor, LCD, and RTC disabled.
Note 8: Regulator, brownout monitor, and LCD disabled; RTC enabled.
Note 9: Regulator enabled, brownout monitor enabled, and LCD and RTC disabled.
Note 10: I

OL(MAX)
for all outputs combined should not exceed 35mA to meet the specification.
Note 11: When DVDD is switched off, SDA and SCL may obstruct the line.
