This device provides outstanding performance in ultrasonic applications. The embedded programmable micro controller offers maximum flexibility to adapt to various applications.
The advanced and very reliable echo detection in combination with comprehensive digital signal processing (advanced filters, automatic thresholds, echo peak detection, sensitivity time control, ...) optimizes short and long range detection performance. The new ultrasound signal coding realizes high robustness against noise, environmental conditions and other ultrasound sources.
DSI3 communication with up to 444 kbit/s per sensor enables a high payload data transfer to reduce system reaction times. Both point-to-point topology and bus mode are supported.
The powerful 32-bit Arm® Cortex® -M0 offers many features for special analysis, evaluation and debugging purposes (e.g. envelope and raw data output).
