CC2640R2F: Preferred pins for I2C?

Jason Gardner

Part Number: CC2640R2F

Are there any preferred pins for I2C on the CC2640R2FRHB? I notice that on the board file GPIO1 and GPIO0 are used for the UART? Any GPIO pins I should stay away from for I2C or interrupt pins?

Jason,

From the CC2640R2 TRM:

I2C can be mapped to any available I/O. You should take into consideration your board layout as well as if you will need any high drive strength or analog I/O and plan your pinout accordingly. If you are using 4-wire cJTAG, you should not use the corresponding JTAG pins.

Regards,

Daniel
