AM2612: Drive strength for PSRAM

Manuel Philippin

Part Number: AM2612

Hello team,

what is the default driver strength for AM261 when connected to PSRAM?
Is this set to 50 Ohm?

Does the PHY tuning algorithm adjust to this?

Best regards
Manuel

    PHY tuning algo doesn't compensate for drive strength and drive strength is a parameter in flash/psram config space, controller will only send a control command to set the drive strength to a required value. So you can basically use application to set the same.
