CC2640 RSM Package - Simultaneous Serial Protocols/PinMux

_Lina

Hi Team,

Could you describe the serial protocols and how they may be used on the RSM package? Datasheet indidcates just 10 GPIOs rather than specifying pins for communication. For example, can I use UART and I2C simultaneously, or do they share the same pins? The data sheet and TRM are not clear on this (or I missed it).

You can freely route I/O to peripheral modules to any GPIO's on the device.

Follow up,

I did find this in the TRM:

But the pin diagram indicates that pins 13 and 14 are for JTAG. Does that mean its JTAG or I2C on those pins?

From this diagram it looks like all the serial interfaces are separate and it shouldnt be a problem to use I2C and UART at the same time. Please confirm.

Best,
