TC1912

The TC1912 offers a 32 bit TriCore based microcontroller/DSP, which is mainly designed or automotive telematics applications. Due to its high integration, this icrocontroller/DSP offers high system performance at minimized cost. Typical elematics functions processed by RISC-, DSP- and speech- (CODEC) modules are now ombined in one component. This combination of the CODEC and standard peripherals SSC/SPI, ASC and IIC), makes this engine tailored for a wide variety of telematics pplications: navigation, emergency call, speech interface or communication interface.

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