XM112 Pulsed Coherent Radar (PCR) Module Datasheet, v1.0 Abstract The XM112 module is tailored for customer evaluation and for OEMs who wish to have the shortest time-to-market. The XM112 can be used as a controlled module, application running on external host where XM112 is controlled by register based protocol. The XM112 can also be used as a stand-alone module where customer can embed their application on top of RSS (Radar System Software), using the RSS API (Application Programming Interface).

XM112 Pulsed Coherent Radar (PCR) Module Datasheet, v1.0 3.5 Software options The XM112 module can be used in two regimes: • • Stand-alone module: The module has got no dependency on external controllers. The application is customized to a specific use case by the customer and runs on the embedded MCU. The customers application is accessing the RSS API via a software interface. Controlled module: The module is connected to an external controller where the customer runs their application software.

Note that supply voltage conditions (E.g. slew rate) need to be taken into consideration according to ATSAME70 data sheet, ref [2]. 4.2 System functions The XM112 module supports Running and Sleep system power states, see XM112 Module server User guide, Ref [4] for further information. Module RESET is supported by activating NRST pin (active low).
