AWR2243: Unused pin connection question

Ltech

Part Number: AWR2243

Can the unused and/or API disabled OSC_CLKOUT (A14), MCU_CLK_OUT (N9), GPIO (N13), BSS_LOGGER (R4), MSS_LOGGER (R3) and RESERVED (G13) pins be connected to GND?

Hello,

If unused you can just leave them floating. I recommend to bring out the logger pins and OSC_CLKOUT pin to test points for debug purposes.

Dear Adrian, there's a desire to ground all these pins. Please answer what the implications of doing it are per pin. Thanks, Lauri

Hello,

You can also ground the pins but I would recommend to do it through a weak pulldown resistor to limit the current consumption.

No, as mentioned you can ground the pins.
