Other Parts Discussed in Thread: MCF8315C-Q1, MCF8315C
Tool/software:
Hi support team all.
I have received the following inquiry from my customer.
Q1:
The SPEED/WAKE pin is connected to the AVDD pin.
The speed control is set to analog input.
When the power is turned on, the device does not start any operation.
I cannot access it via I2C.(I cannot read or write.)
Why is this?
At least, I could not find any information on the datasheet.
Is this a specification that is not mentioned in the datasheet?
Q2:
I would like to drive the SPEED pin at 100% duty without controlling it externally.
This is not possible with the MCF8315A, so please tell me a product that can clear this issue.
An additional condition is that the product has the same package size and pin arrangement.
I found the MCF8315C-Q1 on the web.
However, there was no information in the datasheet of this product that could be used to determine whether this is possible.
Best regards,
Higa
