Which Kinetis devices have EzPorts?

chadwilliams — Wed, 11 Mar 2015 14:20:42 GMT

I am considering a design that uses 2 Kinetis processors and having the Master MCU update the firmware on the second MCU via a spare DSPI port.

Usually this would require a custom boot-loader or implementation of JTAG, but the Ezport looks to simplify this task because its SPI.

I'm trying to select a small, low power Kinetis that has Ezport using the Parameter search tool on the Freescale website, but there is no column I can see that indicates whether or not the device is equipped with an EzPort.

Is there a list of devices that have EzPort?

Do any of the MKL ( lower power devices ) have EzPort?

Hello Chad,

regarding MKL devices, only KL33, KL34 and KL43 seems to include EzPort.

Best regards,

Hello Chad Williams:

All of the parts in the Kinetis K family have EzPort, except for K02, which is an entry level MCU.

As for Kinetis L devices, unfortunately none of them have the EzPort interface.
