80 / 93 page

4 Functional Description

• Hardware-triggered automatic temperature monitoring, supporting two wake-up modes

• Configurable temperature offset based on the application scenario for improved accuracy

• Configurable temperature measurement range

• Support for Event Task Matrix (ETM)-related events and tasks

Pin Assignment

The temperature sensor does not directly interact with IOs, so it has no pins assigned.

4.2.3.3 ADC Controller (ADC)

ESP32-P4 integrates two 12-bit successive approximation ADCs (SAR ADCs) for measuring analog signals from

up to 14 pins.

Feature List

• HP ADC and LP ADC controllers can control the SAR ADC via software

• 12-bit resolution

• Analog input sampling from up to 14 pins

• HP ADC controllers:

– Multi-channel sampling control module with configurable channel sampling sequence

– Mode control module supporting dual HP ADC sampling

– Two filters with configurable filter coefficients

– Two threshold monitors that trigger an interrupt when filtered data exceeds a high threshold or falls

below a low threshold

– Continuous transfer of conversion results to memory via the GDMA interface

• LP ADC controllers:

– One-shot sampling mode

– Sampling in sleep mode (e.g., Deep-sleep)

• Event Task Matrix (ETM) support for various events and tasks

Pin Assignment

The pins of the ADC controller are multiplexed with GPIO16–GPIO23, GPIO49–GPIO54, the interfaces of two

analog voltage comparators, and the third RMII interface of EMAC.

4.2.3.4

Analog Voltage Comparator

ESP32-P4 integrates two analog voltage comparators. These comparators rely on special pads that support

voltage comparison functionality to monitor voltage changes on these pads.
