Hardware parameters
IDO-SOM2D01 Core board power management
According to the power supply timing requirements of SSD201, the core board leads out two core board power supply pins(SYS_3V3，AVDD_RTC).
VDD_RTC (96PIN core board) must be powered for a long time, and the standby battery is powered for a small current consumption. After shutdown, maintain the internal RTC power supply with a current of 1uA.
VCC_SYS (core board 1PIN) is the main power supply for the core board, with a supply voltage of 3.3V and a peak current of 400mA.
| Power pin | Minimum value | Maximum value | Electric current | Power supply ripple requirement |
|---|---|---|---|---|
| SYS_3V3(INPUT) | 2.97V | 3.63V | peak current 400mA <100mA (standby) |
< 30mVrms |
| AVDD_RTC(INPUT) | 2.9V | 3.63V | < 500uA | < 30mVrms |
Power consumption test
| Test project | Test methods and procedures | The test results | Note |
|---|---|---|---|
| maximum power consumption | Dc3.3v power-on test. After the system starts, test the power supply | 3.3v/400mA |
