Note 1: Data in the Typical column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only and are not
tested.
2: Incremental current while the module is enabled and running.
3: LCD is enabled and running, no glass is connected; the resistor ladder current is not included.
4: LCD is enabled and running, no glass is connected.
5: This is the module differential current when the USB module is enabled and clocked at 48 MHz, but with no USB cable
attached. When the USB cable is attached, or data is being transmitted, the current consumption may be much higher (see
Section 27.6.4 “USB Transceiver Current Consumption”). During USB Suspend mode (USBEN = 1, SUSPND = 1, bus
in Idle state), the USB module current will be dominated by the D+ or D- pull-up resistor. The integrated pull-up resistors use
“resistor switching” according to the resistor_ecn supplement to the “USB 2.0 Specification” and therefore, may be as low as
900Ω during Idle conditions.

1.6 — 3.6 V A/D monitoring the VBAT pin using
the internal A/D channel
Note 1: Measure A/D value using the A/D represented by the equation (Measured Voltage = ((V
BAT/2)/VDD) * 1024) for
10-bit A/D; Measured Voltage = ((VBAT/2)/VDD) * 4096) for 12-bit A/D.
