TMS320F28P650SK: TMS320F28388S vs TMS320F28P650SK for motor controller / servo drive

Part Number: TMS320F28P650SK

Tool/software:

Hello, I am trying to distill and understand the practical trade-offs between the two uCs. The drives will use EtherCAT for field bus and control single axis of motion BLDC.

Hi Matt,

Both devices support EtherCAT and motor control. The PWMs on the F28P650SK have new added features. Speed, performance and throughput for both devices are similar however if you look at the cost efficiency, the F28P650SK is at an advantage. See https://www.ti.com/lit/pdf/spruiz2 for general differences between the two devices.

Regards,

Joseph
