AM2634-Q1: What is the value of Pull-up/Pull-down resistor for LVCMOS pin?

Will Gao

Part Number: AM2634-Q1

Hi BU experts,

In AM263x datasheet, the LVCMOS pins are almost with pull type of PU/PD. But the PU/PD resistors' value are not mentioned in the datasheet. Please help check internally with this value.

Thanks and Regards,

Will

Hey Will,

Thank you for your patience while OOO last week. I have looped in the associated design experts to provide details. We have also filed the SITARAAPPS-2960 ticket to ensure this information is added to the datasheet.

Best Regards,

Zackary Fleenor

Hey Will,

Thank you for your patience. Proving internal resistor values below. These details will be included in the next release of the datasheet.

Pull-Up Resistor

Min = 13.5 KOhm

Typ = 33 KOhm

Max = 173 KOhm

Pull-Down Resistor
Min = 15.7 KOhm

Typ = 30 KOhm

Max = 64 KOhm
