Hello,

Please tell me about IMO accuracy for Automotive PSoC4000S CY8C4024LQS-S411.

There is IMO accuracy spec in the datasheet like below.

We can see +/-2%.

But there is IMO accuracy in the Design Wide Resources of PSoC Creator like blow.

We can see +/-4%.

Why??

Ishii-san,

The +-/4% when VDDD(VDD) settings is under 2.0V for PSoC4000S/PSoC4100S is not true. The datasheet is correct.

This rule is only applicable for PSoC 4000 series, not applicable for PSoC 4000S/4100S.

The defect will be fixed in the future in PSoC Creator.

Regards,

Ryan
