Profile: Infineon Technologies North America Corp. produces devices for applications including memory, power, micro controllers, communications, and consumer products. Our product line includes micro controllers, mobile sensors, wireless communication products, de-modulators and chip cards. TC1791 is one of three premium derivatives of the AUDO MAX family. It's CPU provides high-end microcontroller performance combined with sophisticated DSP capabilities and dedicated safety features. The new TriCoreTM version 1.6 offers a significantly increased floating point unit performance, and an integer division unit in hardware. Furthermore, memory protection is optimized and branch prediction is enhanced by a new buffer system. Equipped with up to 4.0 MByte of embedded flash, and a total of up to 288 KByte SRAM (which now comes with error code correction ECC), our KP10x is a pressure sensor system for the detection of side crashes in passenger cars. In this application, the pressure sensor is assembled in a module located within the car's side doors. When the door is compressed due to a side impact, the KP10x provides a signal pulse which is proportional to the pressure change inside the door. The height of the signal pulse depends on the relative pressure change. Therefore, the output signal is independent of the ambient pressure.
