At the Embedded World show 2003 in Nuremberg, Infineon Technologies launched its latest microcontroller (MCU) products: a cost-optimised 16-bit microcontroller, and two new members of its 32-bit family of telematics gateway/audio processing microcontrollers.
"Infineon microcontrollers provide electronic intelligence for millions of industrial and automotive products, computer peripherals and consumer goods," said Frank Grobe, senior manager product marketing Microcontrollers, business group automotive and industrial at Infineon. "Many people do not realise how greatly the adoption of these products changes the way we live, by improving the efficiency of motor driven systems and bringing new capabilities to machines and products we use every day."
C164SV
The C164SV is a cost-optimised but powerful microcontroller specifically designed for use in multiphase brushless DC motor controls and smart-drive applications, says Infineon. They are used in white goods, pumps, and fans. This device uses the C166 architecture offering superior realtime performance. The C164SV also features a powerful peripheral set, including a flexible and intelligent pulse width modulation unit that generates tailored signals for power bridges. Those signals include death time generation and several protection mechanisms. The pulse generation including the synchronised ADC conversion works widely autonomously from the CPU, says the manufacturer, while offering fast conversion time to optimise the control algorithm. The combination of those features simplifies control of electrical motors.
The C164SV is pin-compatible to the C164CM, so that the user gains new system development possibilities and is flexible to add features like the CAN-bus without extensive redesign.
TC1910 and TC1912
The TC1910 and TC1912 are two new members of Infineon's family of telematics gateway/audio processing controllers. The products are designed for use in a wide range of automotive and industrial applications. Target platforms include modular and integrated infotainment subsystems like hands free car kit with voice control, communication gateway, remote diagnostics, elevators, airconditioning systems, shutters and alarm equipment which could integrate voice-control in future as well. The TC19xx family also supports digital audio processing, such as decoding MP3 files or Windows media application (WMA) files.
Based on Infineon's 32-bit TriCore unified processor architecture, all TC19xx members combine RISC, CISC and DSP functionality in a single core. An integrated high-performance audio CODEC enables embedded speech processing functions such as acoustic echo cancellation and noise reduction without the need of additional external components. The devices are fully software compatible to the existing TC1920 telematics controller.
In addition to the TC1910, the TC1912 offers an integrated TwinCAN controller and a third asynchronous/synchronous serial interface (UART-like ASC). Key software packages available for the TriCore-based TC19xx family include Bluetooth stacks and profiles, MP3 decoding algorithm, voice and GPS data processing, etc.
