TC1920

The TC1920 offers a 32 bit TriCore based microcontroller/DSP, which is mainly designed for automotive telematics applications. Due to its high integration, this microcontroller/ DSP offers high system performance at minimized cost. Typical telematics functions processed by RISC-, DSP- and speech- (CODEC) modules are now combined in one component. The combination of dedicated automotive peripherals (CAN, J1850) and standard peripherals (ADC, SSC/SPI, ASC and IIC), makes this microcontroller/DSP the engine tailored for a wide variety of telematics applications such as navigation, emergency call, speech interface or communication interface.

Note: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
During absolute maximum rating overload conditions (V_IN>V_DD or V_IN<V_SS) the voltage on VDD pins with respect to ground (V_SS) must not exceed the values defined by the absolute maximum ratings.
