Which MPC5xxx for more computing performance than the MPC5675K

[sebaboard]

For the moment, I use a mpc5675k for an inverter with quite some heavy calculation.

So I use the two cores of the 5675 and two FlexPWM modules in adaptation of the need for a specific hardware topology.

Now, I need more #computing power.

It seems natural to use the mpc5775k (higher speed, 3 cores) but it is not yet available.

Someone has an idea of a good candidate for higher performance and few re-design?

Hi,

Well MPC5775K is intended to be used mainly for ADAS applications.

The MPC5744P is replacement for MPC5675k, but is apply only locksteped z4 core. I am not sure if that is enough computing power for you.

But there are also devices like MPC5777M/C, MPC5746R which brings more computing power, but missing FlexPWM module.

The most reasonable choice I see in latest S32 generation. S32R274 which has a lot of computing power and also FlexPWM and motor control modules. This device is available for mass market.

S32R Radar Microcontroller - S32R27|NXP

Thanks for your answer Peter.

MPC5744P, as you said, would lack of computing power

S32R274 has only one FlexPWM module

So I should wait the MPC5775K or rework my software design in order to use the eTPU or the eMIOS modules :smileysad:
