IWR1443BOOST: IWR1443BOOST vs IWR1642BOOST

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, IWR1642, IWR1843, IWR6843

Hello,

I have purchased the DCA1000EVM, IWR1642BOOST and IWR1443BOOST kits to prototype some proximity measurements at close range (less than a meter). 


The reason I selected both IWR1642 and IWR1443 was due to the application examples available from TI for short range proximity. One example used the on-board DSP and the other did not. The chip will ultimately be interfaced to an FPGA for post processing but an on board DSP could be helpful.

There seems to be a lot of similarity between the radio architectures of the mmWave Radar devices and variations in peripherals. Some assistance on narrowing down the improvements for the 2nd generation chip will be helpful.

Essentially, what are the similarities and differences between the IWR1642 and IWR1443 devices.

Best,

~Alicia 

  • Hi Alicia,

    So the IWR1642 has the on-chip DSP while the IWR1443 instead has a hardware accelerator (HWA). Because of this the IWR1443 consumes substantially less power.

    Although I would IWR6843 for almost all non-automotive applications. It possess both the DSP and HWA and is what most of our latest device software is for. (Similar device is IWR1843 which is in the 77 GHz band which is reserved for mostly automotive applications).
