CC1352P: Questions about CC1352 vs. CC2652

Lauren Mayfield
Expert 7935 points
Part Number: CC1352P

  1. In looking at the Data Sheet for the CC1352, it looks like it has the same capabilities of the CC2652 except the CC1352 also has support for the Sub GHz radio communication (loses a couple of GPIO pins, pinout a little different but the other capabilities are the same) and is non radio firmware work done on the CC2652 (i.e, ADC, ...) compatible with the CC1352?
  2. On the CC1352, can one 'dynamically' switch between using the Sub GHz and 2.4 GHz radios (for the moment, exclude any antenna issues, just when booting the microcontroller, is there a way to indicate which radio you want to use, so one unit could function in either world when configured/selected to do so?
  3. Depending on your answers, we may be ordering a few 1352 based launchpads.  We are pretty sure of this but are the different supported Sub GHz boards(i.e. the P1, P2, ... flavors) because of the antenna that comes with the board?  The data sheet indicates the 1352 radio can be configured in quite a few Sub GHz ranges, the associated launchpad boards indicate support , for instance, a particular range within the Sub GHz => LAUNCHXL-CC1352P-2 – SimpleLink™ multi-band CC1352P wireless MCU LaunchPad™ development kit, 2.4 GHz up to 20 dBm, 868/915 MHz up to 14 dBm.

Thanks,
Lauren

    To simplify: CC2652 is a subset of CC1352. meaning that you both chips can do the same with the exception of CC2652 only supporting 2.4 GHz. The DIO count is a bit different since CC1352 require more pins to the RF interface. The Simplelik software is written to enable to with very small effort be able to move the software between different devices in the family. For CC1352 vs CC2652 the only difference is the RF interface, all the other periphials are equal.

    For a typical use of CC1352 using both sub 1-GHz and 2.4 GHZ the 2.4 GHz part is typically running with a stack (BLE, ZigBee etc). To run more then one protocol at the time, take a look into the DMM (https://dev.ti.com/tirex/explore/node?node=AEKDw4UXFWWpjzogXjgVAQ__pTTHBmu__LATEST) for details.

    The 20 dBm PA supports a wide frequency range. Dependent on the frequency band you want to use the HPA (High PA, 20 dBm) the BOM has to be different and hence different versions of the CC1352P Launchpads.

    If you could provide more information on what you want to test we can point you to the relevant Launchpad to buy.
