AWR2243: AWR2243P : I2C Slave Configuration

user5244356

Part Number: AWR2243

We are developing a 4-chip Cascade Radar.

Previously, the AWR2243P was configured through SPI communication, but now it is intended to be configured through I2C communication.

The current situation is set to Functional I2C Mode through SOP, but I2C Address of AWR2243P can't read.

Of course, the I2C addresses of the four AWR2243P have been set differently in hardware so that they do not collide.

If there is a document that can be guided, please recommend it.

Hi,

Can you please share more details on "Previously, the AWR2243P was configured through SPI communication, but now it is intended to be configured through I2C communication"?

As far as I know there is no change in AWR2243P and AWR2243.

In the past, we set the SOP mode to 001 and used it as a functional SPI mode.
What I'm trying to do now is to set the SOP mode to 111 and use it as a Functional SPI mode, is there a separate guide document?

[SOP2 SOP1 SOP0] = [0 0 1] -> Functional SPI mode
[SOP2 SOP1 SOP0] = [1 0 1] -> Flashing mode
[SOP2 SOP1 SOP0] = [0 1 1] -> debug mode
[SOP2 SOP1 SOP0] = [1 1 1] -> Functional I2C mode

Hi,

So you intend to operate the device in SOP7 mode? Can you please refer the link below?

The above link talks about the single chip mode, Only, but should be similar in cascade mode too.
