Part Number: MCT8316A
Other Parts Discussed in Thread: MCF8316A

Hi support team.

I received some questions form my customer.

1. Why is there no VDIG_IL specification?

2. How is the maximum electrical frequency of 3kHz calculated?

　I can't find the electrical specifications or description in the datasheet.

Best regards,

Hi Daisuke,

Thanks for posting in MD forum.

Input logic low voltage is 0.25*AVDD

Electrical frequency is calculated based on the bandwidth of the processor.

Hi Aaron-san

Thank you for your reply.

Could you tell me more about how to estimate electrical frequency?

What limits the maximum spec of 3kH?

What is the maximum value of MCF8316A?

And please tell me the reason.

Best Regards,

Higa

Daisuke,

Maximum electrical speed spec is dictated by the processing speed of the controller. Maximum value for MCF8316A is 1500 Hz.

Hi Vishunu-san

Thank you for your reply.

I understand that the controller is the internal processing core, is it right?

Thanks and Best Regards,
