MCF8315A: Please explain differences to MCF8316A

Eric Raquette

Part Number: MCF8315A
Other Parts Discussed in Thread: MCF8316A,

Hello,

I have a board with MCF8316A and was waiting for a new revision of the chip with errata fixes.

Earlier threads said that it would be called MCF8316B.

Now a new chip called MCF8315A is available with lower max current (ok for our motor).

But does MCF8315A have the same errata as MCF8316A or are the I2C issues solved?

Please update the FAQ and/or release errata documents för the different MCT831xx and MCF831xx devices.

Regards,

Eric

Hi Eric,

The I2C issues are solved on the MCF8315A. You can think of both MCF8316B and MCF8315A as having same algorithm ROM. Here is an E2E FAQ that can serve as a selection guide for MCF831x devices and shows the similarities and differences: https://e2e.ti.com/support/motor-drivers-group/motor-drivers---internal/f/motor-drivers---internal-forum/1172043/faq-mcf8316a-selection-guide-for-mcf831x-devices?tisearch=e2e-sitesearch&keymatch=MCF8316A%20FAQ#

You may also notice that the erratas are fixed in "MCF8316B/ MCF8315A" as stated in the FAQ.

Best,

Robert

Hello Robert,

I can not open that link, it is from motor-drivers--internal.

But good to know that the I2C issues are solved at least.
