high-current drive MKE04Z128VLD4

Thank you for helping.

1. MKE04Z128VLD4 44pin is used.

As you can see, does this package support high current output?

2. “8 PINOUT” in the MKE04P80M48SF0 manual stated “PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0, and PTH1 are high-current drive pins when operated as output.”
I thought I could use that function.

3. In the notes of `` 5.1.1 DC characteristics '', `` 2. Only PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0 (64-pin and 80-pin packages only), and PTH1 (64-pin and 80- pin packages only) support high current output. "
I found that description after creating the board.

I think it ’s very unfriendly.

So far, complaints about confirmation and manual unkindness.

Hi jun,

MKE04Z128VLD4 really has high current pin. PTB4, PTB5, PTD0, PTD1, PTE0, PTE1 still are high current pins.

"Only PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0 (64-pin and 80-pin packages only), and PTH1 (64-pin and 80- pin packages only) support high current output. "

I have to say this sentence looks have problem. I'm sorry for that.

Regards,

Jing

Thank you for your teachings. It is said that Japanese is difficult to understand because the subject is ambiguous, but English has a similar situation. understood. PTH is not a 44-pin type. The understanding was shallow. Other than that, I was relieved to know that it was a 44-pin type.
