If IOVDD <2.5V, GPIO VOLTAGE_SELECT registers should be adjusted accordingly. See Section 2.9 for details.

ADC performance will be compromised at voltages below 2.97V
5.4. Power Consumption
The following data shows the current consumption of various power supplies on 3 each of typical (tt), fast (ff) and slow
(ss) corner RP2040 devices, with four different software use-cases.

NOTE
For power consumption of the Raspberry Pi Pico, please see the Raspberry Pi Pico Datasheet.
Firstly, 'Popcorn' (Media player demo) using the VGA, SD Card, and Audio board. This demo uses VGA video, I2S audio
and 4-bit SD Card access, with a system clock frequency of 48MHz.

NOTE
For more details of the VGA board see the Hardware design with RP2040 book.
Secondly, the BOOTSEL mode of RP2040. These measurements are made both with and without USB activity on the
bus, using a Raspberry Pi 4 as a host.
The third use-case uses the hello_dormant binary which puts RP2040 into a low power state, DORMANT mode.
The final use-case uses the hello_sleep binary code which puts RP2040 into a low power state, SLEEP mode.
Table 637 has two columns per power supply, 'Typical Average Current' and 'Maximum Average Current'. The former is
the current averaged over several seconds that you might expect a typical RP2040 to consume at room temperature
and nominal voltage (e.g., DVDD=1.1V, IOVDD=3.3V, etc). The 'Maximum Average Current' is the maximum current
consumption (again averaged over several seconds) you might expect to see on a worst-case RP2040 device, across
the temperature extremes, and maximum voltage (e.g., DVDD=1.21V, etc).

NOTE
The 'Popcorn' consumption measurements are heavily dependant on the video being displayed at the time. The
'Typical' values are obtained over several seconds of video, with varied colour and intensity. The 'Maximum' values
are measured during periods of white video, when the required current is at its highest.
