Dear Community,

Could you tell me the DMIPS and CoreMark for the following models of microcontrollers?

・CY9BF218TPMC-GK7E1

・CY9BF106NAPMC-G-JNE1

Can we use SAF-C161PI-LF CA to replace SAF-C161PI-LF 3V CA directly? What's the difference between these two products? Is the difference only working voltage?

• Is it normal for 802 and 803 to be in the same package?

I think I2C timing on Document Numver 002-08542 Rev.*D Page100 for transmit.
Because the document's timing chart include start condition.

I want to know I2C receive timig (data setup time and data hold time).

Please let me know I2C receive timing.

Dear Community.

During the debugging of CY9BF524L, The P5 port did not output when used as I2C,Changing it to GPIO cannot output either.

What special settings do I have if I need to use P5?

thanks!!!

Hi,

The datasheet (002-08541 Rev.*D, page93) describes I2C timing specifications,
but the receive timing could not be verified.

Because the timing chart is from the start condition when SCL=H and SDA is falling,
We recognize that this is a timing specification for transmit data.

Could you please provide the data setup time and hold time for receiving?

Dear Community,

I read the data sheet and checked the requirements for the crystal from the microcontroller. (Page 65, 8. Handling Devices.)
The load capacitance of the crystal unit for sub-clock is listed as 6pF to 7pF.
Is there a recommended load capacitance for the crystal unit for the main clock as well?

Device : S6E2C4AJ0AGB10000A
