33793

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33793/D Rev 10, 07/2003 33793 Distributed System Interface (DSI) Sensor Interface The 33793 is a slave Distributed System Interface (DSI) device that is optimized as a sensor interface. The device contains circuits to power sensors such as accelerometers and to digitize the analog level from the sensor. The device is controlled by commands over the DSI bus and returns measured data over the bus. DISTRIBUTED SYSTEM INTERFACE (DSI) SENSOR INTERFACE Freescale Semiconductor, Inc...
