Notes
1.ESD1 performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 ), ESD2 performed in accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 ).
2.Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device.
3.Freescale's Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.




Description

The 33793A 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.
