AM3352: I/O pin maximum input current

Denny%20Yang99373

Part Number: AM3352
Other Parts Discussed in Thread: AM3354

Hi team,

We want to use a external resistor to pull up the IO of am3352.

But we can't decide which value of resistor can been used, could you please help to find what it the maximum input current of I/O?

Like: LCD_PCLK,LCD_VSYNC,GPMC_CS,GPMC_AD....

thanks!

BR,
Denny

I/O pin input currents are listed in section 5.7 of the AM335x Datasheet Rev. J.

Hello,

Please, Are they the maximum input current of I/O ? In the table , IOH/ IOL is only the testing parameter of VOH/VOL, not maximum current.

Look forward to your replay ,thanks !

These are CMOS inputs. There is practically no input current.

I am talking about Input leakage current, not about IOH/IOL, which is output current.

Thank you for your reply.
I want to know the maximum sink current of the IO port as output , Like: LCD_PCLK,LCD_VSYNC,GPMC_CS,GPMC_AD....

because We want to use a external resistor to pull up the IO of AM3354, it will be decided by the maximum sink current of the IO port

6mA.
