Hi Folks,

I've been having a hard time finding any information about the

electricals of the Dragonball.

Anybody know what the drive capabilities of individual I/O pins are?

Thanks,

Tim

See table 6 of the reference manual.

According to Table 6 (Maximum and Minimum DC Characteristics) of the i.MXL Datasheet (MC9328MXL, Rev. 8, 12/2006) :

VOH - Output high voltage (IOH = 2.0 mA) = 0.7 * VDD as minimum.

This means 2mA of current load as minimum.

VOL - Output low voltage (IOL = -2.5 mA) = 0.4 V as maximum.

That is – 2.5 mA as minimum.
