FS26 SBC VDDIO pin current

[mogilipuri_harish]

hello team

we are using FS26 in our deigns we need what is load current on VDDIO pin in FS26 SBC.

Hello Harish,

unfortunately we do not have this value. There is many variables influencing the VDDIO current consumption. However, the VDDIO pin is recommended to be supplied from any of the FS26 regulators. Lowest power capabilities have LDO1 and LDO2. 400mA. So you can be sure, that the VDDIO power consumption is never higher, than 400mA.

Hello

we are planning to connect this VDDIO pin from external LDO is it ok?

[A] Yes, you can use external LDO to supply the VDDIO.

hello team

in OTP mode we need VDDIO supply before regulator power on. how is it possible if we connected VDDIO to SBC LDO's regulator output? refer figure 72 in product datasheet (DS616030-FS26 Product Datasheet 3.0(3.0)).

Hello Harish,

the VDDIO pin in the Figure 72. flowchart is meant as external event. Meaning that is valid, when the VDDIO pin is supplied from an external source.
