Part Number: MSP430FR2355

Hello

I am Using MSP430FR2355 Part

In data sheet max current is mentioned Current across the whole chip including IO currents +50(max)

GPIO current not mentioned in data sheet .

I need Help To calculate current consumption .

How should i calculate ?

Please check 5.12.6 Digital I/O Typical Characteristics on MSP430FR235x, MSP430FR215x Mixed-Signal Microcontrollers datasheet (Rev. D)

the max high level and low level output current is ~25mA on digital GPIO.

Thanks

thanks You For Reply

1) 25mA is that Singe pin current or port wise current ?

Hello

Please check the note 1 of Table 5-12: The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop specified.

So, I think 25mA is the singal pin current.

Thanks!
